Management System

Management System Overview, Promotion Structure

Our group-wide Safety and Environmental Management System keeps individual activities proceeding toward common goals under a common philosophy.

System Overview

This management system consists of long- and short-cycle activities.
In the long-cycle activities, which are designed for the entire group, we are making continuous improvements based on common goals and criteria by checking achievements based on reports about site audits and from sites and by reviewing the management system.
For site-specific short-cycle activities, we have an ISO 14001-compliant management system and the Occupational Health and Safety Management System (OHSMS) in place.

Taiyo Yuden Management Philosophy The CSR Charter and Code of Conduct will be defined, measured, and analyzed based on the Taiyo Yuden Group Safety and Environmental Charter, and based on that, we will improve and control. And we will strive for continuous improvement. Additionally, each site will establish a Plan, Do, Check, Action safety and environmental management system. For each site, the group safety, health and environment organization will respond to the group's safety, health and environment medium-term goals, operational standards, group safety and environment documents, laws and regulations, and major risks. Each site submits an accident/performance report, and site safety and environmental audits verify each site and the content of the report. Management View also discloses activity results to outside the company.

Promotion Structure

The officer in charge of safety and environmental affairs appointed by the President and Chief Executive Officer has overall responsibility for building and managing the promotion structure for Taiyo Yuden's Safety and Environmental Management System.
Safety and Environmental MS Committee, the Environmental Promotion Committee debate and decide policies and issues to be addressed. Each manager of sites then converts his/her decisions into actual plans matching the characteristics of each site, and takes charge of publicizing, enforcing and promoting these concrete targets.

Audit

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 8 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 directly cause environmental pollution or occupational accidents.

Number of Nonconformity Instances Found with External Audits

A pie chart showing that 1PLAN (plan), 6DO (do), 1CHECK (check), and 0ACTION (review) were performed for a total of 8 cases.

Nonconformity Examples

Details of nonconformities
The procedures for reviewing the emergency response drills that had been conducted were insufficient.
Corrective/remedial actions taken
The relevant rules were revised to ensure that emergency response procedures are reliably reviewed, and training was implemented to the personnel concerned.

Details of nonconformities
Some waste containers had deficiencies in their identification labels.
Corrective/remedial actions taken
The rules on identification labels for waste containers were revised, and training was implemented to the personnel concerned.

The RBA-VAP audits for FY2025 have been completed at 5 domestic sites and 3 overseas sites.

Internal Site Audits

Audits of site safety and environmental activities at regularly scheduled intervals allow us to compare sites.
(Domestic sites: Once every two years, Overseas sites: Once every three years)
In FY2025, site audits were conducted to verify compliance with customer requirements and the safety, health, and environmental requirements of the RBA Code of Conduct, as well as the implementation status and maintenance of safety and environmental risk countermeasures.
During the audits, auditors reviewed documents and conducted on-site inspections regarding such matters as the controls for potential hazards based on customer and RBA requirements, management of required protective equipment, emergency preparedness, management of chemical substances, waste, air quality, and water quality, and education and training.
The audits revealed deficiencies in the areas of protective equipment management, fire extinguisher management, and labeling management.
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

  • There were some deficiencies in the management of protective equipment inspection records.
  • Materials placed around some fire extinguishers obstructed access to them in the event of use.
  • Some deficiencies were found in the information shown on the GHS* labels on waste liquid containers.

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 20 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.

Other Audits

On-site inspection of waste disposal contractors (Sites in Japan)

During FY2025, we inspected and audited 22 companies (5 collection, delivery, and intermediate processing companies; and 17 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.
