Efforts and Status
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 FY2025, we addressed issues identified on the basis of the analysis results of the Seventh Safety Awareness Survey as a core theme across the organization. To ensure that common rules for all employees are firmly established, we strengthened the improvement cycle by continuing to conduct individual feedback and follow-up training by issue, in addition to on-site verification. We also conducted risk prediction training a total of eight times for employees at sites in Japan and overseas with the aim of firmly establishing highly effective safety behaviors and improving risk sensitivity. As a result, the Eighth Safety Awareness Survey confirmed further improvement in employees’ safety awareness.
We will continue to conduct the Safety Awareness Survey and improve safety awareness of each employee to promote a culture of workplace safety.
Machine
- Enhancing the level of facility safety design for designers
- With the objective of ensuring our machine safety
activities conform to global standards (ISO and IEC), we are reviewing the Safety Standards
for Group Machines, which define measures against risks common to production machines to
enhance safety measures for them.
In FY2025, in light of the growing use of next-generation industrial robots such as collaborative robots, we focused on developing equipment safety experts (R-SA: Robot Safety Assessors) who are capable of properly implementing and evaluating robot safety measures, in order to build workplace environments where employees can work with peace of mind. Through these efforts, we strengthened our organizational framework. In addition to developing equipment safety experts (SA: Safety Assessors and SSA: Safety Sub-Assessors) who have advanced expertise in equipment safety design, we are also developing designers and persons in charge (SBA: Safety Basic Assessors), thereby continuously strengthening our framework.
We will continue our efforts to reduce occupational injuries associated with machines.
Method
- 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 FY2025, in addition to implementing risk countermeasures for work in hot environments, we reassessed procedures for confirming the condition of employees suspected of heatstroke, reporting such cases, and providing first aid. We then made improvements to ensure safer and more reliable responses to the issues identified.
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 associated with tasks that require workers to handle
chemical substances.
In FY2025, we conducted verification testing by an external specialized organization with the aim of reducing the risk of heat generation and ignition caused by waste contaminated with chemical substances. Based on the findings obtained, we verified storage methods for waste that may generate heat or ignite and reviewed management procedures, thereby further enhancing safety.
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 FY2025, to improve the effectiveness of occupational health and safety training, we checked employees’ understanding immediately after training and conducted regular on-site monitoring to assess whether what they had learned was being put into practice. By continuously confirming the process from knowledge retention to behavioral change, we enhanced the effectiveness of training.
Going forward, we will continue our efforts to deepen the level of checks to create safe and hygienic workplaces.
Health
- 1 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 to prevent mental health problems.
In addition to conducting legally required stress checks using the New Brief Job Stress Questionnaire, we also conduct surveys on presenteeism*2 and the incidence of harassment within the organization.- 【Approach to individuals】
-
-
We provided regular advice and guidance to new graduates and mid-career hires who had experienced changes in their living environments.
-
We provided support and guidance to employees identified as having a high level of presenteeism.
-
We conducted stress checks for employees assigned overseas and also recommended counseling.
-
- 【Organizational approach】
-
-
We conducted surveys based on the results of group analyses of stress check results.
-
We provided feedback on the survey results to the managers responsible for each department and implemented measures to improve the workplace environment in order to enhance psychological safety.*3
-
In addition to these initiatives, we launched seminars aimed at improving each employee’s self-care capabilities.
The incidence rate was 0.71%, achieving the lowest level in the past five years (see G1).
We will continue to enhance training, work closely with industrial physicians, psychiatrists, and industrial counselors, and work on mental health care so that all employees can work with peace of mind and motivation.Mental Healthcare System
G1: Incidence rate

Under its management philosophy of “Employee Well-Being,” Taiyo Yuden is committed to health and productivity management in order to help improve productivity and creativity by building a foundation for safe and secure work and creating an organization where employees can work with vitality. As part of these efforts, we have established health indicators, known as Focus 5, diet, nonsmoking, exercise, sleep and stress, along with target values, and are implementing various measures to achieve these targets.
In FY2025, we implemented the following health measures in line with each item of the Focus 5 health indicators.-
[Diet]We continued to measure vegetable intake.
-
[Nonsmoking]We promoted efforts to reduce the smoking rate.
-
[Exercise]In addition to measuring lower-limb muscle strength, we supported the establishment of exercise habits by offering courses on exercises that can be continued without difficulty and streaming videos on improving walking posture.
-
[Sleep]Analysis of an employee survey revealed that the main cause of insufficient sleep was stress. Accordingly, we implemented measures focusing on the relationship between stress and sleep.
-
[Stress]We implemented preventive activities through individual and organizational approaches.
In external evaluations, these initiatives were evaluated, and we received the following certification.
