▶
▶

The RBA-VAP audits for FY2023 have been completed at 7 domestic sites and 4 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 FY2023, 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 including label management, emergency preparedness, management of fire extinguishers.
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 of the hazard labels(GHS*) on the chemical containers were inadequate.
The update and management of the first-aid equipment map were inadequate.
Some items on the list of the monthly fire extinguisher self-inspection were inadequate.
* GHS : The Globally Harmonized System of Classification and Labeling of Chemicals

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 36 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 FY2023, we inspected and audited 34 companies (19 collection, delivery, and intermediate processing companies;
and 15 intermediate processing companies). The results showed that all inspected operators are processing and disposing ofwaste appropriately. The operators have also been classified into three ranks from the results of these inspections, with thefrequency of future inspections varying depending on the rank of the operator.

Trends in Environmental Accounting

Environmental Accounting Standards
1.

The sum total of the costs for complying with environment-related laws and regulations,the costs incurred purely for the purpose of improving our environmental impact,
and the EMS operation costs are calculated. However, in cases where environmental
preservation costs partially overlap the costs for other purposes, the latter shall be
deducted and the balance shall be applied.

2.

Depreciation costs shall be the current fiscal year's depreciation expenses at theenvironmental conservation facilities.

3.

If a clear-cut distinction cannot be made between the environmental cost and that forother purposes, if 50% or more of the content is environment-related, the full amount canbe counted as the environmental preservation cost.

4.

The cost-effectiveness by saving energy is yielded from the reduction of either the rated
dissipation or the operating time or both.

5.

The cost-effectiveness by reducing and recycling waste is calculated as follows:

Lowered costs through reducing waste and recycling =[Unit cost of waste treatment in the prior fiscal year (JP¥/ton) – Unit cost of waste
treatment in this fiscal year (JP¥/ton)] × Amount of waste generated (tons)

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.

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. To respond especially to climate change, which is a global issue,
the targets have been set with the aim of achieving carbon neutrality. 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 (Scope1), Indirect emissions from energy use (Scope2) and Indirect emissions other than from energy use(Scope3). 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 FY2023, the GHG emissions by the entire group increased by 22,000 t-CO2e compared to FY2022. Specifically, theemissions by the sites in Japan increased from 168,000 t-CO2e in FY2022 to 173,000 t-CO2e and those by the overseas sites
increased from 228,000 t-CO2e in FY2022 to 245,000 t-CO2e (see G1).
The amount of energy used by the entire group was 273,000 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 FY2023 was 151,256 MWh.

Efforts on Indirect Emissions Other than from Energy Use (Scope3)
In recent years, there has been an increasing demand from our stakeholders to disclose information on Scope3 emissions,in addition to information on Scope1 and Scope2 emissions. In order to respond to such a demand, we are striving to keep
track of our Scope3 emissions. To reduce Scope3 emissions, we started engagement with our suppliers.

Efforts to Address Climate Change 4-1

11

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 of climate change on society, such as frequent storms and floods, is increasing, the role of companies inachieving a decarbonized society is becoming more important. As we aim to improve our corporate value with a focus on
both economic value and social value based on our Medium-term Management Plan 2025. we consider that strengthening
the measures to respond to climate change is one of the most important business challenges.
While we promote manufacturing based on the decarbonization concept to achieve carbon neutrality in order to tackle theglobal issue of climate change, we have set the Medium-term target of reducing GHG emissions by 42% compared to FY2020
by FY2030 based on the SBTs and thoroughly promote energy saving, energy creation, and the utilization of renewableenergy.
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 enhancing
information disclosure in accordance with the TCFD recommendations.

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.
In addition, there are directors who have expertise and experience in ESG and sustainability on the Board 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.

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 21,197 yen will be imposed on each ton of GHG emissions in 2030 and 37,853 yen in 2050, we forecast theeffects on carbon prices. Carbon prices are set based on (IEA World Energy Outlook 2023 (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 700 million yen as of 2030
and by 4.5 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 200,000 t-CO 2 (see G2), and the impact of the carbon price will be about 4.5 billion yen.

G1：Carbon price effectStrategy

G2：GHG emissions trends

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 Scope1 emissions toward the achievement of carbon neutrality.

■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 25 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 are no overseas sites that are currently considered to be at high risk, and there is no change in the grade in the
future. As for storm surges, there are no domestic and overseas sites that are currently considered to be at high risk and there is no change
in the grade in the future.

Risk management
Regarding climate-related risks, we assign Executive Operating Officer who is a responsible director of safety andenvironment, 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 thesocial situation analysis, interviews with customers and suppliers, and ESG-related engagement process with investors as
tools to identify risks and opportunities related to climate change. The impact of these risks has been assessed in relation totheir financial impact and management strategy.

Indicators and targets
GHG emissions
The Taiyo Yuden Group has set the target of reducing GHG emissions through its business activities by 42% by FY2030
compared to FY2020, which is consistent with the 1.5℃ scenario, to contribute to the global initiatives to limit the temperaturerise to 1.5℃. In order to achieve this target, we are steadily promoting the efforts to reduce GHG emissions through measures toimprove production efficiency and to use renewable energy as well as to smoothly move forward with our plan by introducing theenergy-saving measures and photovoltaic facilities. We plan to use electricity generated from 100% renewable energy at the twodomestic sites in FY2024 and further reduce our GHG emissions.

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.

Man
Intensive basic training and fostering “Awareness of safe behavior”
To create a safe workplace culture, we are conducting activities to help employees increase
their knowledge of health and safety so that they can perform their work with such knowledge
in mind.
In FY2023, we worked on the challenges identified on the basis of the results of the analysis of
the fifth Safety Awareness Survey of the employees working at the sites in Japan. As a resultof quantitatively visualizing the effects of protective equipment to workers and strengthening
the training on the right way to wear it, it was confirmed in the sixth Safety Awareness Surveythat improvements had been made. We also conducted the new Safety Awareness Survey ofthe employees working at the overseas employees in FY2023, analyzed the survey results,
and visualized the challenges.
We will continue to conduct the Safety Awareness Survey and improve safety awareness ofeach employee to promote a culture of workplace safety.

Safety Awareness Survey(overseas sites)

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 FY2023, we developed a system that enabled us to identify the cause when trouble
happened, implement measures, and apply them to other sites more consistently andswiftly by putting the identification labels on all equipment to make it easy to check theimplementation status of safety measures of equipment and by centrally managing the resultsof the assessment conducted on the basis of the equipment safety standards.
We will continue our efforts to reduce occupational injuries associated with machines.

MethodThe results of the assessment

Safe work without inconsistencies
We are upgrading and reviewing procedures to standardize them and make them safe and consistent so that employees can work
more safely.
In FY2023, we improved the safety levels in the workplace and the management levels for emergency preparedness by analyzing
customer needs, industry needs, audit findings, verifying and reviewing the effects of the best practices on inspection of the safety
devices of the production facilities and the eye wash stations to be used in an emergency, and standardizing the methods.
We will continue to strive toward promoting a safe working environment from a common perspective.

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 FY2023, as a measure against the risk when cleaning the equipment using organic solvents, we verified and reviewed theorganic solvents to use and the production method and shifted to less harmful substances to mitigate the risk of the handlingchemicals.
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 goneunnoticed).
In FY2023, we verified and reviewed the measures for the risk of falling accidents while
walking at each site. We also made efforts to create a safer workplace by identifying new risks
from a professional perspective and giving instructions on how to make improvements basedon the cases of advanced efforts, as well as confirming the effectiveness of the measures by
having the safety and health staff members conduct on-site audits.
Going forward, we will continue our efforts to deepen the level of checks to create safe andhygienic workplaces.

Health1 Reducing incidences of mental health problems
Taiyo Yuden developed a system*1 to reduce the number of employees with mental health problems and are making efforts toprevent mental health problems.
In addition to conducting statutory stress checks using the new Occupational Stress Simple Questionnaire, we also conduct
surveys on work engagement*2 and the harassment rate in the organization.
As part of the approach to individuals, we made efforts to prevent mental health problems by holding interviews with new
employees and mid-career hires whose living environments had changed to check their physical and mental health and by having
the industrial nursing staff hold interviews with employees who were suspected of being at high risk of mental health problems. In
addition, in this survey, we also conducted the stress check on the employees working at the overseas sites.
As part of the organizational approach, we provided feedback on the results of the group analysis of the stress check results to thepersons in charge of each department and discussed measures to implement to improve the workplace environment in order toenhance psychological safety*3 in the entire organization.
Thanks to these efforts, the incidence rate remains the same as the previous year at 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 and motivation.

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 FY2023, we implemented measures with a special focus on “Exercise” and “Sleep”
in the Focus 5 indicators. As part of the “Exercise” measures, we held an event in which
participants measured their health status using walking form measurement devices and bodycomposition analyzers, under the theme of “walking” that anyone could practice easily at
any time. We visualized participants’ walking form, muscle mass, amount of body fat, andother attributes to provide opportunities for them to improve their lifestyle habits by enhancing
their daily physical activities. As part of the “Sleep” measures, we conducted e-learning forpeople having a desk job so that they could correctly understand sleep and held seminars
on sleep for shift workers and new employees. In addition, as shift workers were likely tohave sleep problems, we conducted a questionnaire survey of all the employees who worked
in shifts to collect information to consider measures for the improvement of the quality ofsleep and visualized the challenges. Other measures we implemented include the efforts toquit smoking, improvement of the canteen, and health promotion measures by the Health
Insurance Society (walking event).
