Safety and Environmental Audits
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 10 nonconformities. The root causes were analyzed and corrective action was promptly taken in response to each issue. The nonconformities were minor issues related to the management systems and would not cause environmental pollution or occupational accidents.

the contractor was inadequate. make sure that chemicals were stored in accordance with the rules and the status of compliance was examined on a regular basis.
Domestic sites: Once every two years Overseas sites: Once every three years
The RBA-VAP audits for FY2024 have been completed at 6 domestic sites and 2 overseas sites.
Internal Site Audits
Audits of site safety and environmental activities at regularly scheduled intervals allow us to compare sites.
In FY2024, we performed site audits to examine the status of compliance with customer requirements; the RBA code of conduct's safety, health, and environmental requirements; the status of implementation of the measures against safety and environmental risks; and the status of maintenance. 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, management of chemical substances, waste, and air/water quality, and education and training.
The audits revealed inadequacies including education and training, management of protective equipment, and management of safety risks.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
Though education and training were conducted, some participants did not understand adequately. The management of gas mask cartridges was inadequate.
There was a risk of stumbling over a package sticking out into a passageway in a warehouse and falling down.
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 25 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 top
management that the management system has been effective in complying with the Taiyo Yuden Group's policies and goals.
On-site inspection of waste disposal contractors (Sites in Japan)
During FY2024, we inspected and audited 34 companies (14 collection, delivery, and intermediate processing companies; and 20 intermediate processing companies). 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.
