INTRODUCTION 

TDK’s Sustainable Development Policy

Founding Spirit

Corporate Motto
Contribute to culture and industry 
through creativity

In 1935, Dr. Yogoro Kato at the Tokyo 

Institute of Technology received a visit from 
Kenzo Saito, who later founded TDK (initially 
Tokyo Denki Kagaku Kogyo K.K.). Dr. Kato 
expressed the opinion that “all of Japanese 
industry so far relies on borrowing from the 
West. Unless we use our own brain power, it 
cannot really be called Japanese industry. We 
need to apply Japanese creativity to develop our 
own industry.” During the visit, Dr. Kato 
showed Saito a magnetic material called  
“ferrite” that he had developed together with 
Dr. Takeshi Takei. The potential of this  material 
at that point was still a total unknown.

What is ferrite?
A magnetic body sintered with metal oxide 
as the main component. The birth of this 
new material marked the beginning of a dra-
matic evolution in electric and electronic 
technology on a worldwide scale. In 2009, 
the Institute of Electrical and Electronics 
Engineers designated ferrite as an IEEE 
Milestone, recognizing 
it as a development 
with significant 
impact on the 
advancement of 
industry and society.

sively used as a core material for deflection yokes on cathode-

ray tubes. The move toward bigger screens was also supported 

by improved performance of the deflection yoke cores.

TDK, established by Kenzo Saito with the purpose of commercializing this origi-

nal Japanese invention, was one of the original venture enterprises that came out 

of university research. In 1937, the Company was the first worldwide to successfully 
market ferrite cores for use as components in communication equipment. Following 
the turbulent times of WWII and its aftermath, Japan’s reconstruction entered a phase 
of high economic growth. TDK's products played an important role as the sound 
quality of radios and telephones improved and eventually television conquered the 
market. Saito’s stance with regard to technology was to ask what kind of improvement 
it could bring to the development of society. He always strove to create new value 
from the materials level on up. As an embodiment of this founding spirit, TDK has 
continued to reinvent itself and to bring forth innovations that respond to the true 
needs of society.

A new world is coming with advances in the IoT and AI whereby everything will connect via the Internet and behave and be 

upgraded autonomously. In such a world, we expect the following business opportunities to emerge in which we can make use 

of our core technologies.

  Numerous sensors will connect the real world and cyberspace; steady growth is expected in our target non-optical 
sensor market.

  Demand will expand for small, large-capacity, high-reliability batteries supporting the autonomous operation  
of “things.”

  The electrification of automobiles will advance further, with autonomous driving vehicles to appear in the future.

  The IoT will accelerate the digitization of manufacturing and its conversion to a service.

  Renewable energy will spread rapidly.

In our existing businesses, the following changes in the business environment have been clearly observed.

  Shrinking of the HDD market for consumer products, but growth in demand for data centers

  Demand for modularization due to the further enhancement of smartphone functionality

Strengths Sustainably Creating Social Value

Different and difficult to imitate
Materials and Process Technologies

Materials technology elicits raw materials suitable for the targeted properties in a product 
through advanced expertise in complex composition processes and control of additives. 
Process technology maximizes the properties of these materials while also expanding the 
scope of their application in products. Creating “black boxes” for techniques of controlling 
crystal particles at the atomic level, intellectual property, and other know-how makes them 
difficult to imitate overnight.

Achieving our own Monozukuri Innovation
Integrated Production

Integrated production, where everything from materials development to the final product is 
handled in-house, allows TDK to improve its Monozukuri (manufacturing excellence) and 
increase productivity through the introduction of the IoT and robots. Our ability to control 
quality entirely in-house as well gives us a competitive advantage in areas where quality 
requirements are particularly high, including the automotive market.

Foundation of management from a long-term perspective
Customer Base

TDK has built strong relationships with its customers in the automotive, ICT, industrial and 
energy, and other markets. This allows us to more accurately forecast future changes in 
technology trends, and reduces the risks involved in making aggressive R&D and capital 
expenditures.

Innovation foundations and enhanced M&A success rates
Strength of Diversity

TDK has built relationships with the companies it has acquired based not on controlling them 
but on positioning them as equal partners and drawing out their strengths to the greatest 
degree possible. This strength of diversity raises the business portfolio shift success rate, 
promotes the creation of innovation, and serves as a basis for enhancing resiliency against 
climate change.

Capturing business opportunities in global markets
Global Business Base

TDK’s global business base, with an overseas production ratio of 85.4% and an overseas sales 
ratio of 91.8%, not only effectively deepens relationships with customers worldwide and  
distributes risks but also serves as a competitive advantage that will allow us to capture 
business opportunities in the global IoT market.

Future of TDK Suggested  

80 Years Ago by Our  

Pioneering Forefathers

to this challenge, I first asked the question, 

“How was TDK able to shape an 80-year  history 

of growth?” 

  Having been founded in 1935 with the objective 

of realizing industrial applications for the magnetic 

material ferrite, TDK brought ceramic capacitors to 

the market, eventually followed by various passive 

components, magnets, and other products. In this 

way, TDK contributed to the worldwide growth

that was gained through the engagement with  

ferrite helped us enter the field of HDD magnetic 

heads, our materials technology, along with process 

technology for getting the most out of materials, 

formed a solid basis for establishing a wide portfo-

lio of excellent products in a broad range of fields. 

As with these core technologies, the dedication to 

Monozukuri (manufacturing excellence) is a key value 

that dates back to our very beginnings and that will 

continue to enable sustainable and meaningful 

social contributions.

took advantage of the funds from a carve-out of

there are aspects that go beyond the use of funds. 

Expertise in coating technologies from the record-

ing media business, which was shed in the 2000s, 

has found application in such products as lithium 

polymer batteries and functional films. By success-

fully pursuing M&As while retreating from other 

sectors, TDK has kept transforming itself. 

  While thinking about what should serve as a cri-

terion in this transformation process, I found my 

answer in the very motto of our company. In that 

moment, I realized that the founder and the leaders 

that followed him shared the same sense of values 

that I also strongly believe in.

As a result of an increase in the number of parts used on automobiles in conjunction 
with the electrification of vehicles and increased production of HDDs for data centers, 
net sales were ¥1,381.8 billion, a record high, in fiscal 2019. Sales have increased 
over the past 12 years, particularly in Asia, and overseas sales accounted for 91.8% 
of total net sales in fiscal 2019.

As a result of the structural reforms that were initiated in fiscal 2012, we were able 
to establish a firm earnings structure with a good balance among the major seg-
ments. In fiscal 2017, capital gains of ¥144.4 billion were recorded in conjunction 
with the business tie-up with Qualcomm and the agreement to establish a joint 
venture. As a result, operating income in fiscal 2018 fell 57.0% year on year, to ¥89.7 
billion. However, operating income in fiscal 2019 was up from the previous fiscal 
year, and the operating income ratio improved 0.7 percentage points.

ROE and ROA were at low levels following the global economic downturn, but after 
structural reforms were implemented from fiscal 2012, both improved as a result of 
higher net income and other factors. Both indicators were up substantially as a 
result of special factors that resulted in reporting gains on the transfer of business 
to Qualcomm in fiscal 2017 and fell again in fiscal 2018 due to the counteraction to 
those factors, but they increased in fiscal 2019.

The business transfer to Qualcomm in fiscal 2017 resulted in a significant improve-
ment in free cash flow. Funds obtained as compensation for the business transfer 
are being utilized in new M&As in accordance with our growth strategy, and we are 
working to further strengthen our earnings structure. In fiscal 2018, free cash flow 
was negative ¥154.8 billion as a result of active capital expenditures, R&D, and 
M&As, but turned positive in fiscal 2019.

 R&D expenses (left) 

 R&D expenses to net sales ratio (right)

Performance was sluggish from fiscal 2009 due in part to reduced demand for elec-
tronic components resulting from the global economic slowdown and the impact of 
the Great East Japan Earthquake. After structural reforms were implemented begin-
ning in fiscal 2012, however, results gradually improved. As a result of the impact 
from reporting gains from the transfer of business to Qualcomm in fiscal 2017, net 
income in fiscal 2018 fell 56.3% year on year, to ¥63.5 billion, but net income in fiscal 
2019 was up from the previous fiscal year.

Under the three-year Medium-Term Plan covering the period from fiscal 2016 to 
fiscal 2018, TDK made ¥506.9 billion in capital expenditures. Under the current 
Medium-Term Plan, the first year of which was fiscal 2019, TDK is actively pursuing 
capital expenditures aimed at accelerating expansion of core businesses, strengthen-
ing its overseas R&D bases, and accelerating Monozukuri Innovation and expects to 
invest a total of ¥500.0 billion over the three years.

R&D expenses have continuously increased since fiscal 2012, and TDK invested 
¥115.2 billion in R&D in fiscal 2019, a record high, so that it can respond to rapid 
technological innovation in electronics markets and maintain high competitiveness. 
Going forward, we will continue to actively invest in the development of new tech-
nologies and further reinforce our R&D structures.

Compared with fiscal 2010, the overseas production ratio in fiscal 2019 was up 4.9 
percentage points, reaching 85.4%. TDK seeks to establish location-independent 
production systems and is working toward the ability to supply products with the 
same high quality from any location.

The trend of gradual growth has continued since fiscal 2011 due to increases in  
tangible fixed assets and investments. Total assets as of the end of fiscal 2019 
increased 4.6% year on year, to ¥1,992.5 billion. The main positive factors were 
increases in tangible fixed assets of ¥57.5 billion, inventories of ¥19.4 billion, and 
cash and cash equivalents of ¥9.6 billion.

TDK stockholders’ equity was up 6.4% year on year, to ¥877.3 billion, as of the end of 
fiscal 2019. Long-term debt was down ¥86.2 billion year on year and trade payables 
decreased ¥36.9 billion, and as a result, the stockholders’ equity ratio improved 0.7 
percentage points year on year, to 44.0%

TDK implemented personnel optimization measures as a part of the structural 
reforms conducted since fiscal 2012, but has been increasing the number of 
employees to raise competitiveness since fiscal 2016, the first year of the previous 
Medium-Term Plan, and the number of employees reached 104,781 as of the end of 
fiscal 2019. In addition, the overseas employees ratio has been increasing and was 
90.7% as of the end of fiscal 2019.

TDK established the TDK Environmental Vision 2035 and is working to reduce envi-
ronmental load from a life cycle perspective that covers all phases from the use of 
raw materials to the use and disposal of final products. We are aware that CO2 emis-
sions from energy consumption at production sites has a major environmental 
impact within TDK, and we are reducing energy use by implementing energy-saving 
measures through assessment at the time of capital expenditures and creating 
energy management structures.

Structural reforms to bolster integrated production
In Japan, we closed aging passive component manufacturing bases and  
concentrated business sites while adopting in-house production processes 
previously outsourced to collaborating plants. These initiatives focused on 
restoring Monozukuri power through integrated production. Overseas,  
we acted to simplify complex supply chains.

Fruits of structural reforms
Reviewing the results of the previous Medium-Term Plan (fiscal 

2016 to fiscal 2018), sales set record highs each term, with struc-

tural reforms proving effective in strengthening the earnings struc-

ture and operating income also gaining ground. TDK cultivated ATL’s 

lithium polymer batteries and EPCOS’s high-frequency compo-

nents, riding the tailwind of the global expansion of the smartphone 

market. This stance was accompanied by solid efforts to address 

demand for component miniaturization and modularization to keep 

pace with the steady move to higher smartphone functionality, 

honing our underlying technologies to be ready for the next stage 

of evolution.

New strategic positioning to meet  
the next stage of social needs
Against the backdrop of redoubled demand for customization and 

modularization in the smartphone market, needs have grown for 

coordination of the various electronic components mounted in 

those products. To constantly supply customers with optimum 

solutions, TDK moved from traditional in-house self-sufficiency to 

cooperation with IC manufacturers, transferring one portion of our 

high-frequency component business to Qualcomm. Similarly, in 

gearing up to meet the next stage of social needs, from fiscal 2016 

we pursued sensor-focused M&As as a means to field a wide-rang-

ing arsenal of technologies, while solid growth investments were 

advanced to expand sales to the automotive market.

Energy Transformation

Improving energy efficiency

The current world population stands at about 7.7 billion, 

and is expected to surpass 10 billion by 2050.* As the 

consumption of energy rises along with the growth of the 

population, fossil fuels, which so far have been the main 

source of energy, are expected to be depleted, and the 

curbing of global warming has become a global issue. The 

use of renewable energy sources and higher energy effi-

ciency therefore will be pressing concerns.

Products and Technologies for DX

With the rapid evolution of the Internet of Things (IoT),  

big data, artificial intelligence (AI), and robotics,  

along with the information and communication

IoT devices
TDK has the power to meet the pressing needs of the age, such as compatibility with the fifth-
generation mobile communications system (5G) for smartphones, smaller dimensions, lower pro-
files, and higher integration and modularization of IoT devices. TDK has developed sophisticated 
high-frequency components and worked together with IC manufacturers to realize semiconductor 
embedded substrate (SESUB) technology, which enables the design of highly competitive mod-
ules with small dimensions and low profiles. The next generation of electronic components and 
modules with high added value is currently being created in our labs.
  We also contribute sensor solutions in the VR/AR domain. Through the integration of core  
technologies, we are working on bringing next-generation wearable solutions to consumers.

As major efforts are being made particularly in the development of com-
mercial-use drones, the drone market worldwide is expected to rapidly 
expand further. But in order for drones to become actual flying robots, 
improved flight stability along with safety and reliability to prevent colli-
sions and crashes are key issues. Sensors together with software develop-
ment are the major factors in bringing about a true drone innovation. TDK 
has an extensive lineup of non-optical sensor products, and we are also 
globally building a diverse solution business by combining multiple sensors 
and supplementing sensing with software.

In step with 5G
Featuring ultra-high speed, large capacity, multiple simulta-
neous connections, and ultra-low latency, the upcoming fifth 
generation mobile communication system (5G) is attracting 
attention as an infrastructure suited to the IoT society where 
everything is connected to the Internet. Because the millime-
ter waves used by 5G are easily blocked by objects, it will be 
necessary to install a larger number of base stations for small 
cells. According to projections, the share of small cell base 
stations in the total base station count will be around 70% by 
the year 2023. Multi-antennas that support beam forming 
technology, a key aspect of 5G communications, will play an 
important role in such small cell base stations. TDK will be 
supplying so-called LTCC AiP devices, which are proprietary 
antenna in package (AiP) configurations developed by making 
full use of our know-how in low-temperature cofired ceramic 
(LTCC) technology accumulated over many years. In addition, 
we will provide a wide variety of other products and technical 
services that support 5G communication networks, including 
components for communication circuits, sensing applications, 
and noise suppression components, as well as batteries. In 
this way, we will be contributing to the new network 
standard.

In addition to conventional products such as magnetic sensors 
and temperature sensors, we have expanded our lineup of 
non-optical sensors through aggressive acquisitions to meet 
major market needs. In addition, by incorporating IC design 
technology and software technology, we have realized a verti-
cally integrated business model, ranging from the provision  
of materials to advanced composite sensor configurations 
that integrate multiple sensors and ICs. We have linked the 
three business groups “Temperature and Pressure Sensors,” 
“Magnetic Sensors”, and “MEMS Sensors” to create the Sensor 
Systems Business Company* for developing sensor solutions 
on a global basis.

Growth strategy
TDK has devised a growth strategy for expanding the sensor business with a medium- to long-term perspective, and we are 
steadily turning strategy into reality. 
  We will be progressively expanding sales of automotive sensors in a process of organic growth. Redundant sensor configura-
tions combining TMR sensors (benefitting from HDD magnetic head technology) with Hall sensors, temperature and pressure 
sensors, acceleration sensors, gyroscope sensors, time-of-flight (ToF) sensors, and other MEMS sensors will be among the 
growth products. 
  With regard to magnetic sensors in consumer applications including mobile and IoT devices, we are working to capture 
demand for product replacements with TMR sensors offering advantages such as high accuracy and low power consumption. 
For MEMS sensors such as microphones and ultrasonic sensors, we are developing new applications including smart speakers 
and fingerprint authentication.

 The Capability to Provide Social Value 

TDK Contributes to EX  
with Power Electronics Technologies  
Based on Its Magnetics Expertise

In the area of EX (Energy Transformation), the use of renewable energy is, of course, of great importance,  

but it is also essential to realize an infrastructure that minimizes the waste of energy.

This applies to all major stages of EX, namely, the efficient generation, transmission,  

storage, and conversion of energy. TDK’s technologies are at work in all of these areas.

Our portfolio includes film capacitors used for adjusting 
and stabilizing the frequency and voltage of the power 
grid, and which function as output filters for various power 
converters, switches for power grids, circuit breakers for 
substations, and capacitors for medical and industrial 
X-ray imaging equipment. 

Power film capacitors 

Ultra-high voltage

TDK supplies a variety of rechargeable batteries rang-
ing from low-profile batteries in small devices such as 
smartphones to massive high-capacity batteries 
found in wind and solar power generation systems. 
We are especially strong in the field of lithium poly-
mer batteries for smart devices, and are working 
toward a further expansion of their application scope. 
We are also conducting world-leading research into 
surface-mount-type, solid-state batteries.

Lithium polymer batteries

TDK has conducted advanced technical 
research into wireless power transfer with 
not only the electromagnetic induction 
method but also the magnetic resonance 
method. In addition to smart devices, we are 
exploring the commercialization of medium-
capacity wireless power supply systems for 
industrial logistics robots employing the 
magnetic resonance method suitable for 
automated guided vehicles (AGVs), as used 
in factories and warehouses. We are also 
working on wireless power transfer sys-
tems for charging EVs.

We have developed the world’s first chip-type, solid-state battery called 

CeraCharge™, using ceramic electrolyte.

  By harnessing multilayering technology gained in our work with MLCCs, we 

successfully combined high energy density with small dimensions. Instead of 

the liquid electrolyte commonly used in batteries, a solid ceramic electrolyte is 

employed, thereby ensuring a high degree of safety without the risk of electrolyte 

leakage. In the future, the combination with energy harvesting technology will 

eliminate the need for battery replacement, which is expected to result in wide

Three Business Groups that carry TDK’s energy business
TDK’s Energy Solutions Business Company is the command tower for three Business Groups: Power Systems 

Business Group, Energy Devices Business Group, and Energy Systems Business Group.

  TDK entered the energy business in 1974, when ferrite memory cores lost their competitiveness due to the advent 

of semiconductor memory. A successful business transformation of the electronics division was achieved with the 

move to switching power supplies. After the launch of xEVs in the 1990s, we developed a compact, lightweight, high-

efficiency DC-DC converter for HEVs using power ferrite and magnetics technology. Subsequently, we acquired the 

lithium polymer battery manufacturer ATL in 2005, followed by the acquisition of the power supply operations of the 

Lambda Power Group, thereby achieving a full-scale entry into the energy business. In 2018, we formed the Energy 

Solutions Business Company to establish a strong organizational framework for navigating the turbulent EX waters.

Ongoing Improvements in Core Technologies

Since its inception, TDK has grown on the strength of five core technologies: materials technology based on 
ferrite; process technology used to realize materials’ characteristics; evaluation and simulation technology to 
promote development designs; product design technology for merging electronic components into advanced 
and multiple functions; and production technology to support mass output.
  TDK continues to steadily hone this core know-how with the aim of eliminating defects during the pro-
duction process. The goal is the Arubeki-Sugata (ideal process) of Monozukuri through harmony between 
people and robots, moving to realize “Industry 4.0 + Zero Defect.”

Monozukuri Innovation for Sustainable Development

Akita Future Project
Our drive during the 1990s to relocate production sites overseas resulted in 

some issues such as a decreased manufacturing capability, reduced efficiency 

due to movement between sites, and dispersion of core technologies. Since 

around 2016, we have been working on the Akita Future Project, which aims 

to restrengthen manufacturing power through integrated production, accumu-

lating dispersed sites and technologies in Akita Prefecture where TDK was 

founded. The integration of sites for each core technology related to passive 

components minimizes movement between sites, thereby improving effi-

ciency and the fluidity of human resources. Vertically divided business units 

centered on a product-oriented axis, along with horizontal deployment of core 

technologies, make it possible to quickly respond to market changes and 

speed up new product development.

Industry 4.0 + Zero Defect
The combination of Industry 4.0 with our zero-defect product quality con-

cept is a major pillar of the Akita Future Project. In the future, electronics 

are bound to spread to every aspect of people’s daily lives. xEVs (including 

HEVs/PHEVs/EVs) are becoming more widespread, while autonomous 

driving technologies are being readied for practical introduction. In the 

health and wellness sector, remote diagnosis and other advanced tech-

niques are showing high promise. These trends in areas where safety is 

crucial mean that the quality of  electronic components is more important 

than ever. TDK’s “Industry 4.0 + Zero Defect” innovation of industrial pro-

duction combines its drive to eliminate defective products with the 

Industry 4.0 concept.

Pursuit of Industry 4.0 + Zero Defect

Next-generation Monozukuri is becoming a reality
TDK’s quality policy is based on the realization that quality cannot be assured by final inspection. It must be built into the whole 

process, from product design to completion. A multitude of data about the respective production processes is therefore acquired 

and analyzed for quality management, in order to create a production line that does not permit defective output.

In 2016, a model production line based on this approach was completed at our Honjo Factory East Site in Akita Prefecture for 

the fabrication of multilayer ceramic chip capacitors (MLCCs). The design concept of the line involves the utilization of the IoT, 

which makes it possible to autonomously detect pro-

cess problems in real time, so that the line can be 

stopped if necessary, to prevent a defective product 

from reaching the next stage. After verifying the con-

cept at the Honjo Factory East Site, it is to be applied 

to other existing production lines, with the ultimate 

aim of realizing location-independent production, so 

that the same quality level can be achieved at all our 

global sites regardless of physical location. The ideal 

form of a production process that does not allow 

defective output is an example of the Groupwide 

Arubeki-Sugata concept that is being disseminated to 

our sites around the world.

TOPIC

Honjo Factory East Site, Akita Prefecture

Progressively realizing Arubeki-Sugata

The Arubeki-Sugata movement arose out of self-motivated initiatives by employees involved in the 

thin-film coil manufacturing process at the Sakata Factory in Yamagata Prefecture, and it has since 

Inakura Factory  
East Site

spread to all production sites.

  The Inakura Factory East Site in Akita Prefecture 

is our main ferrite core factory that consolidates all 

ferrite core manufacturing processes from other 

factories. After thoroughly analyzing losses in the 

production process and eliminating all factors that 

could negatively affect quality, the process of  

sintering ferrite granules and creating finished prod-

ucts was automated. As a result, a line that formerly 

had a total length of 200 meters is now a mere five 

meters long, while production capacity has 

increased and lead time was significantly shortened. 

Furthermore, quality risks were successfully 

reduced. Another case in point is the Tsuruoka East 

Factory in Yamagata Prefecture where thin-film coils 

(inductors) are manufactured. Processes with inher-

ent quality risks were automated and various other 

initiatives resulted not only in a reduction of quality 

risks but also an increase in productivity by 60%.

  Simply trying to improve yields and reduce costs 

while disregarding remaining quality risks is not the

Promoting development that leverages respective strengths of four global pillars
The R&D activities of the TDK Group are organized in a structure encompassing four geographically different locations, to meet 

the needs of customers in the respective areas. The Technical Center in Japan is the core base of global research and develop-

ment, working on core technologies such as materials technology, passive components, magnets, among others. R&D facilities 

in the United States, Europe, and China are targeting areas related to products that are strong in their respective regions. These 

facilities are also working on product development, applications, and system development. In addition, some regional head-

quarters, which were newly established in an organizational reform, and the Technology and Intellectual Property HQ at the 

headquarters in Japan are collaborating globally to advance research and development beyond the framework of businesses 

and subsidiaries.

Toward being first to market
In research and development, we have been increasing the speed of development by relying on a framework focused on  

specific areas of expertise. The first-to-market principle aimed at being a leader in bringing advanced products to the customer 

requires that development, sales, and production are working in a closely linked arrangement, thereby accelerating the busi-

ness cycle. In order to speedily offer Kotozukuri solutions matched to the actual needs of the market, we have relocated devel-

opment personnel formerly affiliated with the headquarters to the Business Companies.

Lateral deployment of ATL’s speedy development model

ATL strongly dominates the market of lithium polymer batteries for smartphones. The 

secret behind this success is the unrivaled development speed of the company. ATL has 

gained the trust especially of customers who aim to bring products with leading-edge tech-

nologies quickly to the market. By speeding up development, ATL has successfully set itself 

apart from its competitors. We are now actively engaged in laterally deploying this develop-

ment model to the mini cell and power cell sectors as well, in order to create a wide portfolio 

that goes beyond smartphones.

TDK-Lambda, which holds the world’s top share in standardized power supplies 

for industrial equipment, is applying the new paradigm to technology develop-

ment, moving strongly toward being first to market. In addition to using simula-

tion and automated design procedures, the company has integrated its 

development and manufacturing departments, resulting in a drastic shortening 

of development times through designs with a focus on production efficiency.

(BCs) and Business Groups (BGs). By contrast, technologies 

whose practical application is envisioned for five years or more in 

the future are the responsibility of the headquarters. When it 

comes to applying and diverting existing technologies to new

Corporate Governance

Persistently Enhancing Governance Linked to Strategy

Corporate governance reforms

TDK, which first embarked on globalization in the 1960s, remains constantly aware of global standards and 
has worked to strengthen its corporate governance systems. Today, TDK continues to consider measures 
needed to achieve long-term, sustainable improvement in corporate value.

Factors behind strengthening of corporate governance
•  Some businesses will be affected by short-term market fluctuations. At the same time, they can take from several years to as 
long as a decade to see the results of investments in the form of R&D expenses, and management decisions need to be based 
on a medium- to long-term perspective.

•  As a global company, ensuring business moves forward smoothly requires a governance structure that is also compatible with 

the standards of countries in Europe and the Americas.

•  With non-Japanese employees representing in excess of 90% of the workforce on a consolidated basis, TDK needs to consider 

further globalization at the officer level.

Mr. Sumita, who was previously an outside director, has been appointed 

chairman & inside director. Through his experience as an outside 

member of the Audit & Supervisory Board since June 2011 and Outside 

Director since June 2013, he has a deep understanding of TDK’s man-

agement, business portfolio, and so on. From the perspective also of an 

outside stakeholder, he endeavors to make decisions on important mat-

ters and to supervise the performance of duties, as well as to strengthen 

corporate governance.

Reassessing Director composition and  criteria for 
submissions to the Board
The composition of Directors has been reassessed, 
narrowed down to those officers with an overview of 
the entire Company, a shift from the previous inclusion 
of the heads of the individual business divisions. At the 
same time, by changing submission criteria to focus on 
large-scale, companywide investment deals, the Board 
is achieving a deeper level of discussion and more 
rapid decision-making regarding  important deals.

Enhancing Executive Committee Meeting discussions
With the authority delegated to it by the Board of 
Directors in conjunction with the reassessment of 
Board submission criteria, the Executive Committee 
Meeting is now able to engage in deeper discussions on 
management strategy and arrive at decisions quickly.

Reassessing Group administrative structure
A foundation for enhancing business efficiency within 
a global structure has been put in place via a reas-
sessment of Group administrative systems by the 
individual business divisions, headquarters, and 
regional headquarters.

Progress based on the results of primary evaluation by third-party evaluation institution in June 2018

1.  Demonstrating appropriate supervision and advisory functions to steadily achieve the Medium-Term Plan 

In order to steadily achieve the Medium-Term Plan, the Board of Directors has carried out sufficient monitoring and verifica-
tion by reviewing the progress status with Outside Directors and Outside Audit & Supervisory Board Members multiple times 
and in other ways.

2.  Further strengthening the governance and compliance systems 

In order to strengthen the supervisory function in the global business system, the Group management system of each 
Business Division, Headquarters, and Regional Headquarters has been revised by reviewing the organization, job authority, 
and division of duties. It is recognized that the TDK Group’s governance and compliance systems are being established 
through these efforts.

3.  Efficiency of operations of the Board of Directors 

It is thought that the efficiency of operations of the Board of Directors has been enhanced by improving the discussions at 
the Executive Committee Meeting, which is a meeting body prior to the Board of Directors, and revising the criteria for 
agenda items for discussion by the Board of Directors.

Evaluation of the effectiveness by the Board of Directors
Based on the primary evaluation by the third-party evaluation institution, the Board of Directors, after conducting deliberations 
several times, confirmed that the effectiveness of the Board of Directors and its Advisory Committee (Nomination Advisory 
Committee and Compensation Advisory Committee) were sufficiently secured. Also, the Board of Directors confirmed that it is 
continuously enhancing its effectiveness by making improvements based on the results of the Board of Directors’ evaluation in 
the previous fiscal year.

Future issues
(1)  With regard to the Medium-Term Plan, sufficient discussions have been made from the process of formulation to the monitoring 

of the progress, and it is recognized that it is necessary to deepen discussions on longer-term issues in the future.

(2)  It is recognized as a future issue that the Nomination Advisory Committee will deepen discussions on the succession plan (CEO, 
Chairman of the Board, Directors and Audit & Supervisory Board Members, including Outside Directors and Outside Audit & 
Supervisory Board Members) and share basic ideas with the Board of Directors.

Board of Directors’ View of a  
Continuously Evolving TDK

We asked Makoto Sumita, Chairman & Director, and Kazumasa Yoshida, Outside Director,  
to discuss the evolution of TDK’s corporate governance and  
organization as linked to its growth strategy.

of how its decision-making processes and organization 
need to evolve in order to create competitive products. 
Today, I think, they have created a framework that is 
comparable with that of any global company in the 
West, characterized particularly by an increased aware-
ness of the kind of openness and transparency on which 
its overseas members place a premium. They have also 
developed a rapid cycle for reporting to the Board of 
Directors, engaging in transparent discussions, and then 
tying those discussions to solid execution through com-
munication with employees around the world, who in 
turn offer progress reports to the Board.

Mr. Yoshida, tell us how you came to take on an 
Outside Director position?

Yoshida

Since joining Intel Corporation, an American 
company, in 1984, I have consistently worked 
in the field of electronic components. I had been in touch 
with Mr. Sumita during my time at Intel, and he was the 
one who contacted me. As electronic components have 
become a key factor for innovation in hardware, TDK has 
built an extremely broad portfolio, generating a wide 
range of innovations. I thought the opportunity to 
become involved with TDK’s enormous potential was 
highly attractive, and in 2014, I gladly accepted the offer 
to join the Board.

Sumita

At the time, it was clear that the industry was 
moving toward further integration of passive 

components and semiconductors. Then-President 
Takehiro Kamigama came to me to ask if I knew of an 
executive familiar with semiconductors, so I recom-
mended Mr. Yoshida, who had a deep understanding of 
the structure of the semiconductor market and who had 
also distinguished himself as a spokesperson for the 
industry. For TDK, I think his agreement to take the  
position was extremely well-timed.

What is your perspective on the changes in  
governance at TDK since you took up your position?

Sumita

Over the past eight years, I have observed 
TDK from an outside perspective, and I think 

changes in governance began in earnest just in the 
past five years or so. Eight years ago, many Japanese 
companies had yet to acknowledge the importance of 
outside directors. As I recall, the kind of interaction we 
see today, where the business execution side actively 

Makoto Sumita
Chairman & Director

Kazumasa Yoshida
Outside Director

seeks advice from outside directors, was similarly  
lacking at TDK. As momentum grew for governance 
reforms, however, and companies began reevaluating 
the role of the outside director, TDK appointed one of 
its own outside directors as chairman, bringing the 
Company external leadership. These changes have 
entailed more than simple passive acceptance of out-
side demands for a corporate governance code or 
other measures—it may be more correct to see them 
as having actively evolved to take the form needed to 
advance the company’s growth strategy. 

Yoshida

As market conditions have undergone major 
changes, I get the impression that TDK has 

successfully transformed itself while remaining aware 

How are efforts progressing to enhance the opera-
tional efficiency of the Board of Directors, an issue 
pointed out in the Board’s 2018 evaluation of 
effectiveness?

Sumita

We have asked that all important proposals  
go before the Board, and encourage Outside 

Directors and Outside Audit & Supervisory Board 
Members to offer their opinions from the perspective of 
their respective areas of expertise and engage in candid 
discussions. There is a trade-off between conducting 
more fulfilling discussions and efficiency, which we have 
resolved by having the Board focus on larger issues of 
direction, and by using Board meetings as a venue for 

monitoring progress. First, the Executive Committee 
Meeting (ECM), which takes place prior to the Board 
meetings, decided which issues should be discussed by 
the Board and reevaluated criteria for presenting those 
issues thereto. We greatly increased the monetary crite-
ria for capital expenditures and other deals to be 
approved by the Board of Directors, which has led to  
a more careful assessment of the appropriateness and 
effectiveness of large-scale investments based on a 
close examination of their track record and outstanding 
issues. We also reevaluated the composition of our 
Directors. Directors who also serve as the heads of busi-
ness divisions inevitably bring views that are biased in 
favor of their individual businesses. We thus limited 
membership of Directors to those in a position to offer  
a companywide perspective. Meanwhile, we worked to 
delegate authority by having the ECM, consisting pri-
marily of the heads of business divisions, closely discuss 
business-related proposals and submit them to the 
Board. This is how progress was made in enhancing the 
efficiency of Board operations.

Yoshida

Responding to sudden changes in the market 
requires transforming how TDK does business, 

and the traditional decision-making processes need to 
change along with it. At previous Board meetings, the 
business execution side would explain its position using 
vast amounts of documentation. We made the process 
more efficient and more dynamic by intentionally focus-
ing discussion on the issues. For instance, we conduct 
more active discussions by narrowing our focus to ques-
tions such as what issues lie before us in preparing to 
achieve our vision for three years hence and whether 
TDK is capable of solving those issues—and if not, how 
it should go about acquiring those capabilities. Greater 
delegation of authority has led, I feel, to a dramatic 
increase in our decision-making speed.

Business promotion systems also significantly reworked.

Sumita

The most significant aspect of our organiza-
tional reforms was the establishment of 

regional headquarters. Having each region address its 
own financial, accounting, legal, hiring, and compliance 
issues, for example, greatly improves business effi-
ciency. And having our Business Companies in each 
region share their issues leads to improved organiza-
tional strength for TDK as a whole.

Yoshida

Offering proposals based on an integrated  
platform, rather than electronic components 
alone, greatly increases value for the customer. TDK is 
working to integrate a wide range of products, from passive 

62

components to batteries and sensors, providing a common 
platform across a variety of different markets, including 
the automotive, ICT, and industrial and energy markets. 
Organizational reforms, which lead to encouraging lateral 
cooperation, can be seen as a step in that direction.

Sumita

Taking on the risk of entering new businesses is 
important. Still, if this effort to provide a common 
platform moves forward, I believe it is possible to achieve 
what President & CEO Shigenao Ishiguro calls Kotozukuri 
(integrated solutions), even as we work to integrate our 
existing businesses. TDK then has the potential to achieve a 
level of profitability not possible through the sale of indi-
vidual products.

As chairman of the Compensation Advisory 
Committee, Mr. Yoshida, how do you view TDK’s 
compensation system?

Yoshida

With performance and remuneration clearly 
linked and a Compensation Advisory 
Committee—comprising a majority of Outside 
Directors—that conducts transparent evaluations, I 
believe our compensation system is competitive. The 
next step for TDK, where employees overseas represent 
over 90% of total personnel, is to enhance the equitabil-
ity and transparency of its compensation system not 
only at the headquarters but across the Group as a 
whole. While this will not be easily achieved, we are cur-
rently working to correct gaps in the way evaluations 
and remuneration are handled between companies TDK 
has acquired and TDK’s management. If we can do that, 
we can enhance the mobility of our human resources, 
allowing personnel to move laterally between Group 
companies and ensuring an improvement in competi-
tiveness for TDK as a whole.

What about the succession plan?

Sumita

Until last year, I served as chairman of the 
Nomination Advisory Committee, and was 

involved in the nomination of President & CEO Ishiguro.  
I think TDK’s evaluation process—centered on its Outside 
Directors—is effective. That said, with globalization 
advancing to this point, we need to put in place a mech-
anism by which our members overseas can also become 
leaders. TDK has already made progress in compensation-
linked efforts, building a system that allows for side-by-
side comparisons of ability and salary levels. To improve 
the quality of management at TDK, the Nomination 
Advisory Committee also proposed appointing non- 
Japanese and women as Outside Audit & Supervisory 
Board members; one of each was appointed at the end 
of June 2019. Going forward, TDK will continue to 
increase diversity in its Board of Directors.

Yoshida

The members of the Board of Directors are 
highly aware of issues regarding the succes-
sion plan. A framework has been put in place over the 
last year, with Andreas Keller, Corporate Officer and 
General Manager of Human Resources HQ, in charge of 
conducting regular reviews. The Nomination Advisory 
Committee also takes a close look at the experience, 
performance, and career development desires of man-
agement individuals overseas.

How do you view the current Medium-Term Plan 
“Value Creation 2020?”

Sumita

I get the sense that, in the past, people felt 
that a failure to achieve a plan was unavoid-
able in the event of changes in business conditions or 
other assumptions. Under Value Creation 2020, 

however, although business progress may vary from the 
original outlook due to sudden changes in the business 
environment, TDK has a much stronger commitment to 
its financial targets. Rather than revamping the 
Medium-Term Plan in any major way, it focuses instead 
on how to recover from setbacks and still hit its targets, 
as well as on how to expand those businesses with 
growth potential. Even as many companies predict a 
drop in income in fiscal 2020, TDK has presented a plan 
calling for increased income. This is indicative of TDK’s 
attitude that solid achievement of their business plan on 
a single-year basis is crucial to achieving their three-
year plan. I think this has also enhanced their credibility 
in the market.

What about sensors and magnets, where progress 
has fallen behind?

Sumita

Even the MLCC business, which is performing 
strongly today, posted long-term losses until a 

few years ago. By spending the time and funds to inno-
vate production and by setting its sights on the automo-
tive market, the business has been able to achieve high 
profit margins. TDK is looking at sensors and magnets 
with a similarly long-term strategy, but one that assumes 
that, in the short term, up-front investments will con-
tinue. Expanded applications for magnets are seen as a 
certainty, but in terms of market structure, it is also a 
business in which it can be difficult to improve profit-
ability. We are currently investing in the deployment of 
state-of-the-art equipment and automated inspection 
devices, while moving forward with innovations that will 
enable us to offer the market high-value-added prod-
ucts with a variety of features and forms. We expect 
these efforts to contribute to companywide perfor-
mance over the course of the next Medium-Term Plan.

Yoshida

Recognizing that TDK has a track record of 
taking the time to solve difficult issues is what 

enables the Board of Directors to make investment 
decisions. We are confident that sensors will become  
a core technology going forward and want to carefully 
cultivate that potential. The same goes for magnets— 
it may take time, but I think eventually that business will 
also generate solid earnings.

Sumita

In terms of the need to look 10 years ahead 
and view things over an extended time line, 
the same can be said of R&D. With a four-pillar global 
development structure now in place, TDK is currently 
working to leverage each site’s respective strengths, 
collaborating to conduct R&D. We are also developing  
a framework for open R&D utilizing both internal and 
external resources, but it will likely be a while before 
those efforts begin moving forward together.

With Mr. Sumita as chairman of the Board, what 
perspective will you bring to backing TDK’s further 
evolution?

Sumita

For TDK to be successful both in Digital 
Transformation (DX) and Energy Transformation 
(EX), it will require not only moving forward with product 
development but also a dynamic transformation on the 
part of TDK itself. My understanding is that simultane-
ously prompting innovation in these efforts will be an 
important role of the Board of Directors going forward. 
For instance, we currently use business ROA as a means 
of evaluating the profitability of a business, but by 
assessing our businesses in greater detail and present-
ing a target figure for profitability, we believe the busi-
ness divisions and those on the front lines will take it 
upon themselves to effect transformation. This is 
something we hope to discuss as we prepare for the 
next Medium-Term Plan.

Finally, what message do you have for TDK?

Yoshida

Each time I visit the front lines, I am so 
impressed by and proud of how each 
employee takes responsibility for their work and faces 
the challenges they are given head-on. TDK presents a 
very clear story around attempting to discover the 
hidden potential of technology, backed by an equally 
clear-cut message from President & CEO Ishiguro and 
accompanied by action. I hope TDK’s employees will 
continue to work with confidence in their efforts to fur-
ther TDK’s growth. As an Outside Director, I look forward 
to engaging in discussions of an even higher quality 
than before and to contribute to enhancing TDK’s corpo-
rate value.

Sumita

I also believe that TDK’s strength lies in its 
frontline capabilities. It is the individuals work-

ing at the Company’s plants and other sites the world 
over who support TDK through their creativity and inge-
nuity. If the Board of Directors is able to recognize this, 
and bring a similar perspective to their efforts to create 
worker-friendly environments, I think those frontline 
capabilities can be leveraged to an even greater extent, 
in turn significantly expanding TDK’s own potential. With 
that understanding, and as someone who brings an out-
side perspective to the role of Chairman & Director, I will 
encourage proactive interaction both inside and outside 
the Company.

Thank you for your time today.

ROE) in the relevant fiscal year, indicators are set for each division, 
and bonuses vary from 0% to 200% of base salary depending on 
the degree of attainment of targets.
Some stock-linked compensation stock options have a results 
achievement condition attached to them. The results achievement 
condition takes consolidated results under the Medium-Term Plan 
(operating income, ROE) as an index, and varies the number of exer-
cisable options between 0% and 100% of the number of options 
granted, depending on the degree of attainment of targets. TDK has 
established Corporate Stock Ownership Guidelines. TDK makes an 
effort to ensure that eligible Directors and Corporate Officers hold at 
least a certain number of shares in TDK pursuant to their rank, 
including stock-linked compensation stock options.

Promoting diversity in management systems
TDK began encouraging globalization at an early stage, appointing a non- 

Japanese person as a Corporate Officer in 2004 and promoting the global-

ization of management by increasing the number of non-Japanese 

Corporate Officers since then. Today, more than 90% of sales and employ-

ees are derived and based overseas, while 39% of the Company’s Corporate 

Officers are non-Japanese. In recent years, globalization has advanced as 

TDK implemented a number of M&As, and the globalization and diversifi-

cation of management structures is an important issue. We will continue 

to recruit outstanding human resources from around the world under the 

Human Resources HQ established in Germany in 2018.

Framework for Enhancing Corporate Value and Sustainability

Sustainability

Basic Policy

TDK Group Sustainability Vision
As well as aiming to solve social problems through our business on the 

basis of our corporate philosophy, which is our fundamental stance, we 

have formulated a new TDK Group Sustainability Vision. This vision 

proclaims that by fully utilizing TDK’s proprietary core technologies and 

solutions, we will “advance the development of a sustainable society and 

promote the well-being for all people.”

In the formulation of this vision, we again assorted the social 

environment surrounding us from a long-term perspective and studied 

the potential of the TDK Group’s strengths and resources. In the process, 

we heard the opinions of not only management but also external experts. 

  Going forward, we will share this vision throughout the Group, put it 

into practice in our business, and consider and implement specific 

measures toward the realization of a happy society.

In the Value Creation 2020 Medium-Term Plan, which kicked off in 

fiscal 2019, TDK aims for sustained business growth while creating three 

Values. The realization of Social Value, which is one of them, is closely 

related to the United Nations’ Sustainable Development Goals (SDGs).

Technology for the well-being of all people

The TDK Group strives to restore and protect 
the global environment while promoting 
respect for human rights. Through its innova-
tive core technologies and solutions, the Group 
advances the development of sustainable soci-
ety and champions well-being for all people.

The TDK Group’s key CSR issues and the SDGs
The TDK Group seeks to realize a sustainable society, identifying “Contribute to the world through technology,” “Develop human 

resources,” “Consider the societal and environmental impact of the supply chain,” and “Develop and prosper in harmony with the 

global environment” as key issues guiding its CSR activities. TDK’s “Contribute to the world through technology” is based on its 

technologies and products and the external social environment, focusing on fields enabling maximized provided value through 

TDK’s key CSR issues and the SDGs

the SDGs. TDK has clarified social challenges behind the six SDGs below and contributes to the realization of an ideal society in 

which these challenges are solved through its technologies and products. TDK further implements initiatives toward “Develop 

human resources,” “Consider the societal and environmental impact of the supply chain,” and “Develop and prosper in harmony 

with the global environment,” thereby contributing to the various relevant SDGs.

Contributing to the SDGs through technologies and products
TDK contributes to realization of a happy future society through its technologies and products that address six SDGs: Good 

Health and Well-Being (SDG 3), Affordable and Clean Energy (SDG 7), Industry, Innovation, and Infrastructure (SDG 9), 

Sustainable Cities and Communities (SDG 11), Responsible Consumption and Production (SDG 12), and Climate Action (SDG 13).

  These SDGs represent areas in which we feel we can provide maximum value considering the potential of our technologies 

and products to contribute toward solutions to social issues facing us today. In our efforts to draw an ideal society where 

issues are successfully solved, TDK will further develop its technologies and products, thereby contributing toward solutions 

enabling the realization of a happy future society.

Toward the Stage of Utilizing the Strength of Our Diversity

As a result of our advancement overseas, M&A, and other factors, TDK has cultivated a strength of diversity 
formed by diverse human resources from a wide range of regions. Now, TDK is embarking on a global 
human resource strategy to fully display that strength.

The strength of our diversity fostered by 
post-merger integration respecting equality
TDK, which began the overseas expansion of its operations in 
the 1960s, has been actively promoting globalization against 
the background of such factors as the subsequent transfer by 
customers of their manufacturing sites to overseas locations. 
Since the turn of the century, with our eyes on future markets, 
TDK has been boldly carrying out a reform of its business 
structure through M&As. TDK’s post-merger integration 
policy of maintaining relations of equality rather than control 

and respecting corporate cultures has been hugely successful, 
and companies like ATL in Hong Kong and EPCOS (now TDK 
Electronics) in Germany have subsequently come to contrib-
ute enormously to our revenues. In the background lies 
TDK’s thinking that since acquisition targets are companies 
with not only outstanding technologies but also excellent 
managers, human resources, strategies, and operations, the 
probability of success of an M&A increases if these aspects 
are respected and managers of the acquired company are 
delegated authority.

Effectiveness of the strength of  
our diversity
The TDK Group comprises affiliated business companies 
with not just multiple nationalities but also strengths in vari-
ous domains, technologies, know-how, and so on. That is 
the essence of the strength of our diversity. For example, 
while TDK in Japan is strong in passive components, mag-
nets, and magnetic technology, as well as materials technol-
ogy, in which persistent development is conducted from a 
long-term perspective, TDK in the United States, centering 
on InvenSense, has strengths in MEMS sensors, software, 
and so on. In Europe, TDK Electronics (formerly EPCOS) and 
others are strong in industrial sensors and passive compo-
nents, and in China, ATL, for example, has an extremely high 
level of competitiveness in lithium polymer batteries. We are 
building a business model that is best suited to each region 
and product characteristics and ensures exceptionally 
speedy business. Furthermore, this dispersion of regions 
and customers and our wide-ranging product portfolio lead 
to a high degree of resilience against risks of fluctuations in 
the market environment.

Toward the stage of utilizing the strength of 
our diversity
As a result of TDK’s efforts since 2016 to transform its busi-
ness structure through M&As centering on sensors, the 
Company has expanded its business foundations to more 
than 30 countries and regions worldwide. In fiscal 2019, our 
overseas sales ratio was 91.8%, and our overseas employee 
ratio was 90.7%. In the future, in order to supply the best 
solutions through various technologies and products, it will be 
necessary for us to vitalize collaboration among regions and 
among Business Companies. Furthermore, if we can make 
effective use of the different strengths in the TDK Group, we 
will be able to further boost the competitiveness of TDK as a 
whole through the interaction of our fortes. On the basis of 
this approach, as we have been doing so far, TDK will con-
tinue to forcefully promote a global human resource strategy 
aimed at enhancing the fluidity of human resources among 
Business Companies worldwide and discovering and nurtur-
ing human resources beyond national borders, while also 
bolstering the strength of our diversity by maintaining the 
independence of affiliated companies.

Accelerating the advancement of a global  
human resource strategy
Since 2018, TDK has been working on a large-scale reform of its human resource systems. This  

has been driven by the emergence of DX (Digital Transformation) and EX (Energy Transformation), 

two new mega trends that have led us to recognize that gathering human resources from around 

the world who are capable of staying ahead of technological developments, and fostering their 

skills appropriately, is an urgent task if we are to achieve our growth strategy going forward. 

  Specifically, we have set out three core goals—developing the next generation of human 

resources, establishing an efficient global human resource platform, and improving communication—

and have put in place measures and policies aimed at achieving those goals. One of our greatest suc-

cesses to date has been our progress in measuring and visualizing the English and communication 

skills of individual employees across the Group as a whole, and in putting in place various systems 

in conjunction with transnational transfers of personnel. This has allowed for a more flexible 

exchange of human resources on a global scale, while making the process of participating in devel-

opment programs required for advancement and promotion easier and more efficient. During the 

current Medium-Term Plan (covering the period from fiscal 2019 to fiscal 2021), we are primarily  

in the infrastructure-building stage, but we are also making steady progress with more concrete 

efforts, among them developing various Groupwide management development programs for  

management-level and high-potential employees. The main goal is to improve their management 

and leadership skills, which will help foster the development of the existing and next generation  

of strong leaders. Some of the development programs were created in collaboration with various 

state-of-the-art business schools around the world. For the next Medium-Term Plan (covering the 

period from fiscal 2022 to fiscal 2024), we will focus on extending these efforts further into the 

workplace while ensuring the results are carefully validated.

  Obviously, given our current business environment, the need for overwhelmingly rapid transfor-

mation applies to human resource systems as well. In advancing these reforms, we selected individ-

uals from among human resource professionals at Group companies worldwide to be responsible  

for specific areas, including evaluation, training, and hiring. Each of them leveraged their personal 

strengths and exhibited strong leadership in these efforts. As a result, it took us only about two 

years to implement reforms that would normally require four or five years to complete. This may  

be a perfect example of the strength of diversity, an ideal TDK upholds for the entire Company. 

  This kind of global-scale strength of diversity has been demonstrated particularly in recent years 

as we have accelerated our M&A efforts, reinforcing our desire to further solidify this trend through 

our human resource system reforms. By doing so, we hope to help TDK make the leap to being  

recognized for its presence as a truly global company, and a leader among Japanese firms.

nologies and products

TDK continues to pursue new potential and challenges in 
the hope that the application of its unique technologies 
and products will help create a happy future society. This 
enables the realization of Social Value, which is a part of 
TDK’s “Value Creation 2020” Medium-Term Plan and is a

Environmental activities from a life cycle perspective

Groupwide activities from a life cycle perspective
Within TDK Environmental Vision 2035, the declaration is made to reduce the environmental load from a life cycle perspective. This represents 

an initiative not limited to measures at the manufacturing stage in factories and the use stage for customers, aspects outlined in the conven-

tional TDK Environmental Action 2020 policy. To expand in this way, we deem it critical for all TDK Group employees to share the same vision 

and move forward with the same objectives in mind. The “revitalizing and protecting the global environment” expressed in this corporate vision 

refers to the skillful operation of our business hand in hand with the natural environment. Without that commitment, there will be no sustain-

able development on the horizon. The entire Group shares an Arubeki-Sugata (ideal process) and undertakes voluntary initiatives in pursuit of 

that vision.

Initiatives from a life cycle perspective and the concept of environmental load
TDK conducts business on a global scale, and as a result, in order to reduce environmental impact, initiatives are needed that not only reduce 

our own environmental load but also cover the entire value chain. 

  Presented here are the environmental considerations and main initiatives that TDK views from a life cycle perspective and an overview of 

environmental load. Investigations regarding environmental load are being conducted to establish criteria for the TDK Environmental Vision 2035.

Environmental considerations

TDK Environmental Vision 2035
TDK believes that, in order to realize the sustainable development of society, environmental activi-

ties based on a long-term outlook are necessary. In the TDK Environmental Vision 2035, which 

commenced activities in fiscal 2017, toward the realization of our corporate vision, we see our 

Arubeki-Sugata (ideal process) in 2035 to be one of operating with an environmental load that does 

not disturb the natural cycle. Our target, therefore, is “to halve the CO2 emission basic-unit from a 

life cycle perspective by 2035.” This Environmental Vision is based on our recognition that it is the 

duty of a company to minimize the environmental load in business activities, revitalize the natural 

environment, and supply products that contribute to 

customers and society. Moreover, learning from the 

United Nations Framework Convention on Climate 

Change (COP 21) Paris Agreement, which seeks to 

curb global warming by achieving a balance between 

greenhouse gas emissions and absorption sources, 

we are pursuing the TDK ideal of acting to attain our

Society

TDK’s supply chain responsibility
TDK offers high-value-added solutions based on materials and components technologies. As globalization accelerates and we 

expand our target markets, we develop ongoing relationships with a wide range of customers and business partners. Some 

companies are buyers, as well as suppliers, for TDK in certain business areas.

  Responsible management of supply chains is coming under strict scrutiny with the strengthening of legal systems and inter-

national industry initiatives. For example, the United Kingdom passed the Modern Slavery Act in March 2015, and the Electronic 

Industry Citizenship Coalition (EICC) changed its name to the Responsible Business Alliance (RBA) in October 2017. Because 

Important issues at each level of the supply chain

these trends greatly affect TDK’s business environment, it is vital that we take suitable measures in our business supply chains.

  A shared understanding of social issues and common investigative practices is essential for the practical and effective imple-

mentation of CSR in the supply chain. To bring improvements in efficiency to the entire supply chain, TDK is working with other 

organizations from the stage of formulating rules, cooperating with the industry as a whole, and proposing the standardization 

of investigative methods.

Toward zero defects

Zero-defect quality begins in the first stage of development
Zero-defect quality must be designed into our products and processes right from the start. It is our 

responsibility to our customers and to society as a whole that our customers’ products and applications 

function properly and safely for their entire life cycle. Zero-defect quality also means that we manufac-

ture our products without wasting resources, whether we are talking about raw materials, semi-fin-

ished and finished goods in our production, energy, or water. The result is a highly efficient production 

process that contributes to sustainability.

In order to achieve zero-defect quality, we need not only an advanced quality management system 

but also, above all, well-trained and competent staff. That is why we implemented a compulsory train-

ing program for all of our factories at TDK Electronics. We also need perfectly tuned and maintained pro-

duction equipment. We are improving our manufacturing processes with Industry 4.0 methods by 

evaluating production data in real time and employing predictive maintenance to eliminate defect risks 

before they even occur. It is our standard practice to identify and assess such risks during product devel-

opment. Thus, zero-defect quality begins in the first stage of development.

Think for yourself, devise improvements, and implement 
them through team cooperation
As a first step, the risks in 392 operations were methodically identified, result-

ing in a list of 1,702 problems. The Arubeki-Sugata (ideal process) for each prob-

lem and risk was then examined and defined, and a manual to convey the 

information to the manufacturing floor in an easy-to-understand manner was 

created. The aim was a concise, memorable format, with slogans such as “no 

waste, no wobble, no worry.” For example, risks and losses associated with 

transfer operations were reduced (no waste), standardized work operations 

and work layouts were defined to eliminate unevenness (no wobble), and work 

flow lines were designed to enable natural movement without strain (no worry).

  Quality control activities have a particularly important role to play in this 

undertaking. As Tomomichi Hatakeyama, manager of Tsuruoka Higashi Factory, 

puts it, “Think for yourself, devise improvements, and implement them through 

team cooperation.” A wide range of measures has been implemented to that 

end. Staff recite the purpose of their own process daily, to foster a clear under-

standing of the positioning of one’s work within the overall process sequence. 

Tools such as monitors and tablets are used for discussions and to allow 

checking operations via video at any time by anyone. Special areas created 

within the work area are set aside for meetings, allowing teams to get together 

and engage in close communication. “I believe it is only through the steady rep-

etition of diligent actions that zero-defect product quality can be realized.”
