Safety and Environmental Audits

04

Triple audits evaluate each site’s compliance, accident risk management, and the environmental impact situation aimed at
producing continuous improvement.

External Audits

ISO14001 certification audits by certification authorities

Sites with ISO14001 certification underwent the audits required to update or maintain such certification. These audits
uncovered 2 nonconformities. The root causes were analyzed and corrective action was promptly taken in response toeach issue. The nonconformities were minor issues relating to our management systems, and were not directly linked withenvironmental pollution or occupational accidents.

We displaid labels on waste containers andconducted training to ensure that employees
label waste containers in accordance with theregulations.

ACTIONThe RBA-VAP audits for FY2022 have been completed at seven domestic sites and one overseas sites.

Internal Site Audits

Audits of site safety and environmental activities atregularly scheduled intervals allow us to compare sites.

Domestic sites: Once every two years
Overseas sites: Once every three years

In FY2022, we performed site audits to examine the status of compliance with customer requirements, the RBA code of
conduct’s safety, health, and environmental requirements.
In each audit, auditors checked documents and performed on-site audits on matters related to customer requirements/RBA
requirements such as risk management against potential hazards, management of required protective equipment, emergency
preparedness, and management of chemical substances, waste, and air/water quality.
The audits revealed inadequacies in areas such as warning signs, emergency preparedness, and management of chemical
substances.
Countermeasures were implemented for validated inadequacies found during the site audits, and verified its effectiveness.
We aim to improve the level of health, safety, and environmental protection activities for the whole group by globally
incorporating societal requirements in a timely manner and sharing the results after benchmarking products from all sites.
Issue Examples
Some hazard labels in a used fluorescent lamp storage area were not sufficient.
Some eye wash equipment for emergency use was not inspected.
Some chemical subdivision containers were not provided with secondary containment.

Internal Audits

Audits targeting site departments on observance of safety
and environment laws, target achievement, and performance.

Once or twice every year

All sites conducted internal audits of their departments in accordance with their management systems. Priority areas were
determined for each site, and 42 nonconformities were uncovered as a result of conducting internal audits (at sites in Japan).
Corrective action was completed in all cases without delay, and after a follow-up check, it was reported to the managers thatthe management system has been effective in complying with the Taiyo Yuden Group’s policies and goals.

Other Audits
On-site inspection of waste disposal contractors (Sites in Japan)
During FY2022, we inspected and audited 12 companies (4 collection, delivery, and intermediate processing companies; and8 intermediate processing companies). The travel restrictions due to the COVID-19 pandemic prevented us from auditingsome contractors on site. We changed the audit procedures to self-audits for them using documents and photographs(for 7 contractors). The results showed that all inspected operators are processing and disposing of waste appropriately.
The operators have also been classified into three ranks from the results of these inspections, with the frequency of future
inspections varying depending on the rank of the operator.

Determining Environmental Impact ofCorporate Activities

08

Detailed understanding and analysis of the environmental impact of corporate activities is a prerequisite to devising various
measures to improve this.

Material Balance
The Taiyo Yuden Group primarily produces electronic components for delivery to our customers, set manufacturers. Theseelectronic components have a life cycle with only a small environmental impact during use. The bulk is during production, with themain environmental impact arising from energy and water consumption, emissions (including CO2) in the course of manufacture,
waste and wastewater. The Taiyo Yuden Group is striving to improve our environmental impact by first identifying and analyzing
in detail this environmental impact and then taking such measures as minimizing the resources applied and conserving otherenergy and resources by improving production processes. The Taiyo Yuden Group products are used in electrical and electronicequipment, automobiles, and other products which become waste once their product lifetime is over. We are therefore also striving
to remove hazardous substances from these products.

Achievement Levels for
Medium-Term Environmental Targets

09

We set medium-term environmental targets for the Group, and all sites pursue environment impact improvement.

Taiyo Yuden Group Environmental Targets and Results“Strengthening responses to climate change” and “efficiently using resources and helping to build a recycling-based society”
have been set as the materialities of environmental efforts. Especially for climate change, a global issue, we have formulated
targets to achieve carbon neutrality by 2050. To achieve these targets, we will be diligent at saving, generating, and re-using
the energy that drives our manufacturing based on the principle of decarbonization.
To reduce the absolute value of GHG emissions, we set target values in accordance with the SBTs (Science-Based Targets).

Curbing Global Warming

10

There are three categories for greenhouse gases (GHG) emitted during the course of business activities: Direct emissions
from use of energy (SCOPE 1), Indirect emissions from energy use (SCOPE 2) and Indirect emissions other than fromenergy use (SCOPE 3). GHG emissions cannot be easily measured, so we concentrate on energy use and reducing energy
consumption.

Results of Efforts to Reduce Greenhouse Gases and Energy Consumption
In FY2022, the amount of GHGs emitted by the entire group decreased by 63,000 t-CO2e compared to FY2021. Specifically,
the domestic sites reduced their emissions from 195,000 t-CO2e in FY2021 to 168,000 t-CO2e, and overseas sites reduced
theirs from 264,000 t-CO2e in FY2021 to 228,000 t-CO2e (see G1).
The amount of energy used by the entire group was 252,000 kL (crude oil equivalent).
We will continue to review production processes, with a focus on core products, to further improve production efficiency andreduce energy use.
Furthermore, we have been promoting the incorporation of renewable energy in our efforts to combat global warming. The
renewable energy used in FY2022 was 123,212 MWh.
* The following conversion factors were used for these calculations. [Electric power] Japan: factors released by the Ministry of the Environment; overseas: factors provided by the International Energy Agency (IEA); [Fuel] Japan/overseas: factors released by the GHG Protocol.

In response to the recommendations of the Task Force on Climate-related Financial Disclosure (TCFD), we are proceedingwith a scenario analysis of the risks and opportunities that climate change issues pose to society and business, andconsider business strategies based on the results.

Efforts to Address TCFD
As the impact on society of climate-related physical risks, such as frequent storms and floods is increasing, the role ofcompanies in achieving a carbon-free society is becoming more important.
We consider that strengthening the implementation of climate adaptation measures is one of the most important businesschallenges.
To tackle the global issue of climate change, we thoroughly promote planning and working on energy efficiency &conservation, energy creation, and the utilization of renewable energy through manufacturing based on the decarbonization
concept to achieve carbon neutrality by 2050. We have set a reduction target of absolute GHG emissions based on the SBT.
We aim to contribute to the achievement of the international goals set forth in the SDGs and the Paris Agreement throughcollaboration with a wide range of stakeholders. We also recognize the importance of climate-related financial information
disclosure, endorse the TCFD, and are expanding information disclosure in line with the TCFD.

GovernanceWe recognize climate change as one of the important management issues and aim to promote activities for sustainability
issues through business activities throughout the company, and since FY2021, we have held the Sustainability Committee (fourtimes a year) chaired by the President and Chief Executive Officer.
The Committee deliberates on setting materialities sharing of issues, and measures to resolve issues, and reports to theBoard of Directors.
The Environmental Promotion Committee, a sub-committee of the Sustainability Committee sets quantitative targets forclimate change and monitors the status of achievement.
If the targets are not achieved or may not be achieved, the Environmental Promotion Committee needs to investigate thecause and take corrective measures for improvement. The deliberations and decisions by the Environmental Promotion
Committee are reported to the Sustainability Committee, which is its superior committee.

Strategy
１ Identification of risks and opportunities
In order to identify climate-related risks and opportunities that affect our business, we used climate scenarios such as the IEA
and the IPCC to identify them, qualitatively evaluated their characteristics, and conducted scenario analysis.

3 Scenario analysis results■Transition risks: Financial impact of introducing carbon prices on operating costs
Risk

Impact of carbon prices on operating costs in 2030 and 2050

Our climate scenario
analysis prerequisites

Assuming that a carbon price of 18,340 yen will be imposed on each ton of GHG emissions in 2030 and 32,750 yen in 2050, we forecast theeffects on carbon prices. Carbon prices are set based on (IEA World Energy Outlook 2022 (Net Zero Emissions by 2050 Scenario,
Stated Policies Scenario).

Analysis result

We forecast future GHG emissions trends and the financial impact on operating costs if carbon prices were introduced. Under the 1.5°C
scenario, if GHG emissions reduction measures were implemented, costs would have been reduced by about 900 million yen as of 2030
and by 2.4 billion yen as of 2050 compared with the scenario where no measures are taken (see G1). In addition, although we are promoting
the introduction of renewable energy, even if the power is 100% renewable energy, the remaining SCOPE1 emissions in the 1.5°C scenario
will be 260,000 t-CO 2 (see G2), and the impact of the carbon price will be about 7.4 billion yen.

In order to reduce energy consumption, we believe that it is necessary to improve production efficiency by reviewing our production
processes, focusing on our core products, along with promoting the introduction of renewable energy. In addition, we plan to consider
measures to reduce the remaining Scope 1 emissions toward the achievement of carbon neutrality in 2050.

■Physical risks: Impact of intensified extreme weather disasters on sites (Floods and Storm Surges)

Impact of increased weather disasters associated with climate change on our manufacturing sites at the middle and end of this century

Our climate
scenario analysis
prerequisites

We assessed 26 sites inside and outside Japan based on public hazard information and various information obtained for climate change
impact assessment.

Analysis result

We assessed the potential for manufacturing site damage due to intensifying extreme floods and storm surges, and screened sites that
require priority investigation of the impact of physical risks.
We independently graded baseline (current) flood and storm surge risks and assessed the changes in the current to mid-century or end-ofcentury grades based on the RCP2.6 and RCP8.5 climate scenarios.
Regarding floodings, there is one site in Japan that seemed to be at high risk at present, but there was no change in the grade in the future.
On the other hand, there were no sites overseas that were currently considered to be at high risk, but for one site, the risk was assessed toincrease compared to the baseline by 2050 and 2085. Regarding storm surges, there are currently no sites that are considered to be highrisk, and there was no change in the grade in the future.

Risk management
Regarding climate-related risks, we assign Executive Vice President who is a responsible director of safety and environment,
reports and deliberates these issues at the the Internal Control Committee through the Compliance Subcommittee and the
Risk Management Subcommittee in accordance with the group management system.
We refer to social analysis, interviews with customers and suppliers, and ESG engagement with investors as tools for
identifying climate-related risks. The impact of these risks has been assessed in relation to their financial impact andmanagement strategy.

Indicators and targets
GHG emissions
The Taiyo Yuden Group has set targets for GHG emissions; a 42% reduction by FY2030 compared to FY2020 to achieve carbon
neutrality by 2050. In order to achieve these targets, we will steadily promote efforts to reduce GHG emissions through measures
such as the use of renewable energy and the improvement of production efficiency. As part of our measures, we will convert
100% of the electricity used at our R&D center to renewable energy in FY2024.

We strive to reduce environmental effect on biodiversity while coexisting with nature, and we use the 3Rs(reduce, reuse, recycle) to reduce waste and make effective use of water resources.

Results of Reducing Waste
The amount of waste generated in FY2022 by the entire group decreased to 26,300 tons from 28,900 tons in FY2021(see G1).
The waste (including valuables) mainly consists of waste plastic, waste oil, and sludge (see G2).
The domestic final disposal volume increased to 56 tons from 54 tons in FY2021. The waste recycling rate reached 99.5% (see G3).
The overseas final disposal volume decreased to 2,000 tons from 2,300 tons in FY2021 (see G4).
We will continue working to reduce waste volumes, boost in-house recycling rates, and recycle waste into resources at ouroverseas sites.

All employees participate in health and safety efforts based on the Fundamental Principle of Health and Safety outlined in
the Taiyo Yuden Group Safety and Environment Charter and implemented according to
the Occupational Health and Safety Management System (OHSMS).

Fundamental Principle of Health and Safety, and Targets
In order to realize our health and safety philosophy of “creating a workplace where employees can work without anxiety,”
the Taiyo Yuden Group has drawn up group-wide medium-term plans. The medium-term plan is set to prevent industrial
accidents by clarifying action targets for each 5Ms (Man, Machine, Method, Material, Measurement) and by setting a target
incidence rate of injuries and illness for numerically evaluating the result of such efforts.

Principle ofHealth & Safety

In order to ensure the well-being of our workers, who are an important resource of the company, we shall pursue workplaces which always
maintain safety and where employees can work in confidence while maintaining the health of our workers.

continued to promote efforts to make work safer by verifying and reviewing risk measures in
non-routine work. We have also strengthened education based on basic education materials
that have systematically organized items to be followed when performing relatively high-riskwork. In the 5th Safety Awareness Survey conducted in FY2022, we confirmed that most ofitems were improved as the result.
We will continue to conduct the Safety Awareness Survey and improve safety awareness ofeach employee to promote a culture of workplace safety.

Basic Education

MachineEnhancing the level of facility safety design for designers
With the objective of ensuring our machine safety activities conform to global standards (ISOand IEC), we are reviewing the Safety Standards for Group Machines, which define measuresagainst risks common to production machines to enhance safety measures for them.
In FY2022, we carried out appropriate equipment safety assessments and measures for nextgeneration industrial robots that are advancing in sophistication and complexity. In addition,in order to build a safe work environment in which people and robots can cooperate, we
promoted the training of equipment safety experts (R-SA: Robot Safety Assessors) with safetyknowledge about industrial robots, and promoted the standardization of equipment safetymeasures for the introduction of industrial robots. We also regularly held workshops aimed at
upgrading the skills of equipment safety experts (SA: Safety Accessors and SSA: Safety SubAssessors).
We will continue our efforts to reduce occupational injuries associated with machines.

MethodSafe work without inconsistencies
We are upgrading and reviewing procedures to standardize them and make them safe and consistentso that employees can work more safely.
In FY2022, we verified and reviewed the risks of all heavy object handling work and the measures forthese works, and took measures to strengthen measures. Regarding heavy object handling work, we
promoted conversion from management measures to mechanization, and took measures to reduce
heavy manual work and reduce human intervention as much as possible. For heavy lifting that isdifficult to mechanize, we verified various types of back pain prevention equipment, selected themost effective protective equipment, and trained employees on correct wearing methods and work
methods.
We will continue to strive toward promoting a safe working environment from a common perspective.

object handling work

Material
Minimization of toxicity and danger of chemical substances
To minimize the hazards and dangers of chemical substances, we are continuously taking measures against risks associatedwith tasks that require workers to handle chemical substances.
In FY2022, as a measure for the risk of cleaning jigs using organic solvents, we promoted switching to less harmful
substances and mechanization of the work to minimize the risk of handling chemical substances.
We will continue to work toward minimizing the hazards and dangers of chemical substances.

Measurement
Strengthening of checking system
To provide safe and hygienic workplaces, we are working to raise check levels by upgrading and improving the methods for
identifying invisible hazards (or those that have gone unnoticed).
In FY2022, we standardized workplace patrol procedures (checklists) to reduce and minimize the variation in checks during
workplace patrols. In addition, on-site staff had performed the role of checkers to conduct regular workplace patrols until
then, but we started a system whereby health and safety specialists from other sites conduct workplace patrols of eachother’s sites. This has led to the identification of new issues and improvement measures referring to best-practices.
Going forward, we will continue our efforts to deepen the level of checks to create safe and hygienic workplaces.

Health1 Reducing incidences of mental health problems
The Taiyo Yuden Group has developed a system*1 for reducing incidences of mental healthproblems and is conducting preventive activities.
In addition to conducting statutory stress checks using the Occupational Stress Simple
Questionnaire, we also conduct surveys on work engagement*2 and the harassment rate in theorganization.
In the approach to individuals, the industrial nursing staff conducted individual interviews with
Harassment prevention training
employees who were concerned about the risk of mental disorders, and made efforts to prevent
mental disorders. We conducted self-care training to teach stress relief methods and avoidance
methods for individuals identified as suffering from high stress by the stress checks.
In the approach to the organization, we shared the results of the group analysis with the management of the organization, andeach department judged the necessity of training leaders to care about the mental health of their employees and anti-harassment
training to enhance psychological safety*3.
These activities reduced the incidence to 0.73% (see G1). We will continue to enhance training, work closely with industrial doctors,
psychiatrists, and industrial counselors, and work on mental health care so that all employees can work with peace of mind andmotivation.

2 Establishing a healthy lifestyle
Under the management philosophy, “Employee Well-being,” Taiyo Yuden sees employee
health management as a management issue, and is committed to health management
in order to create a foundation for safe and secure work, create an organization where
employees are motivated, and contribute to productivity and creativity. Within this, to advancethese activities both strategically and systematically, we have set health indicators (Focus5:
Food, non-smoking, exercise, sleep, and stress) and established targets, and have beenendeavoring to implement specific health measures to achieve these targets.
In FY2022, we prioritized Exercise and Sleep in the Focus5 indicators as key items andpromoted efforts.
As, for Exercise measures, we carried out efforts to foster employees’ motivation for daily
exercise, such as distributing stretch videos produced in-house, holding stretching and yoga
classes by external instructors, and visualizing the physical condition of employees using awearable device app.
For Sleep measures, we conducted e-learning for desk workers to correctly understandsleep, and held seminars for shift workers and new employees on the topic of sleep disorders.
For other measures, we implemented initiatives to quit smoking, enhanced employee
canteens, and implemented health promotion measures health insurance union and labor
union by (walking events, RIZAP seminars).
As a result, in terms of external recognition, we were selected for the Ministry of Economy,
Trade and Industry’s system Health and Productivity Management Organization 2023
-White 500*4 for the three consecutive years. In addition, as a company that actively works topromote sports activities to promote the health of employees, we were certified by the JapanSports Agency as a Sports Encouragement Company 2023*5 for the three consecutive years.
We will continue to pursue both mentally and physically healthier work environments thatenable our employees to work with vigor.
