Environmental Management
Promotion System
To comply with environmental laws and regulations and promote environmental conservation, our group has established a Central Environmental Committee (held twice a year, with extraordinary meetings as needed), chaired by an executive appointed by the Environmental Officer (President). The Central Environmental Committee reviews the progress of Eco Vision 2030 and the group's environmental issues, and strives for continuous improvement. Important decisions made by the Central Environmental Committee are reported to the Board of Directors through the Management Meeting.
In fiscal year 2025, the Central Environment Committee held two meetings to report and discuss the progress of EcoVision 2030, the promotion of group governance, information on environmental incidents, and the latest developments and future plans for the climate change response roadmap.
Towards achieving EcoVision 2030, each company manages its own targets for business activities, carrying out activities in an integrated manner with its operations. On the other hand, activities such as legal compliance, raising environmental awareness, and communication with local communities are planned and implemented at the district level. In addition, various committees have been established as cross-company organizations to address specialized issues such as carbon neutrality, energy conservation, and chemical substances.
Status of environmental management system development
Our company and nine domestic group companies (as of the end of fiscal year 2025) have obtained ISO 14001 multi-site certification. In addition, one domestic company and 16 overseas companies (as of the end of fiscal year 2024) have obtained ISO 14001 certification through individual company certification.
The percentage of employees in our group who have obtained ISO 14001 certification, both domestically and internationally, has reached 96%.
*Number of companies and employee ratio are as of fiscal year 2025.

Addressing environmental risks
Our group is committed to identifying and mitigating risks to prevent environmental accidents and pollution that may occur as a result of our business activities. We go beyond mere legal compliance and actively promote proactive initiatives.
Where there are regulatory limits for air quality, water quality, noise, vibration, etc., as stipulated by law or agreements with local governments, we set stricter voluntary standards and conduct regular measurements and management. If we deviate from the standards, we take immediate action and thoroughly implement measures to prevent recurrence.
Measures to prevent dust dispersion
In accordance with the Soil Contamination Countermeasures Act, our group installs local exhaust ventilation systems at dust sources in necessary manufacturing processes to ensure reliable suction and collection. The collected dust is passed through high-performance dust collection equipment to minimize its release into the atmosphere. Furthermore, we strive to protect the surrounding environment by thoroughly performing regular filter replacements, inspections, and cleaning to ensure that this equipment always functions properly.
Drainage management
Regarding factory wastewater, it is treated at wastewater treatment facilities at each location before being discharged. We manage it according to our own standards, which are stricter than legal regulations, to prevent the release of pollutants into the environment.
Measures against noise and vibration
We are taking measures to prevent noise from spreading by installing soundproof covers and other measures on equipment that is a source of noise.
Emergency response training
We conduct regular response drills to prepare for emergencies such as sudden accidents. We anticipate potential accidents and their impacts in each department and strive to prevent contamination.
Soil and groundwater investigation and response
Our group conducts necessary investigations in accordance with the Soil Contamination Countermeasures Act. Furthermore, as part of our environmental management, we have been conducting regular voluntary surveys of groundwater contamination at the boundaries of our factory sites since fiscal year 2022. If hazardous substances exceeding the standards of the Soil Contamination Countermeasures Act are detected, we will promptly report this to the relevant authorities and implement appropriate countermeasures in accordance with their guidance.
We also publish information on our website's news section.
PCB management
Our domestic group implements proper management and planned disposal of PCB-containing equipment and waste in accordance with the Special Measures Act on Countermeasures against PCBs, etc. (PCB Special Measures Act). For high-concentration PCBs, we identified target equipment through past surveys and completed the disposal of all equipment by the legally mandated disposal deadline. For low-concentration PCBs, we have also been disposing of equipment identified through past surveys in accordance with the plan. Even if additional low-concentration PCB-containing equipment is detected due to equipment decommissioning, etc., we have established and maintain an internal system and operational flow to complete disposal within the fiscal year in which it was discovered.
Status of compliance with environmental laws and regulations, etc.
Response to violations and complaints in fiscal year 2025
In fiscal year 2025, there were two violations (one of which exceeded the agreed-upon value with the city), zero environmental accidents, and zero complaints. Prompt measures were taken to address the violations and complaints that occurred, and efforts were made to prevent recurrence.
| Company | Situation | Countermeasure | |
|---|---|---|---|
| Violation | Niterra Co., Ltd., Ltd., Komaki Plant | Due to equipment malfunction, untreated wastewater was discharged, and analysis of water samples taken from the septic tank revealed that the SS value (suspended solids) exceeded the value agreed upon with Komaki City (but within legal limits). The alarm system failed to activate, resulting in a delay in detecting the anomaly. |
We updated equipment and reviewed the operation methods of the alarm system. We implemented stricter wastewater monitoring measurement settings within the group to ensure that wastewater levels do not exceed the standard values. |
| Violation | Niterra Co., Ltd., Ltd., Komaki Plant | It was discovered that there had been an underreporting of emissions in compliance with the Fluorocarbon Emission Control Law in 2023. | We developed procedures for complying with the Fluorocarbon Emission Control Law and provided training on these procedures. We also confirmed that there were no other instances of unreported emissions within the group. |
Environmental education
To improve employees' environmental awareness, we conduct environmental education. In addition to hierarchical training, we also offer specialized training such as courses on environmental management systems, procedures for compiling environmentally harmful substances, and environmental laws and regulations (facilities). Starting in fiscal year 2022, we are considering and implementing a shift to video-based training to provide more efficient education tailored to the needs of participants.
To inform employees about EcoVision 2030, we have launched an EcoVision website on our intranet. This site contains information on the background of setting EcoVision 2030, the results that can be expected from achieving the EcoVision goals, specific examples of initiatives, and the monthly/annual environmental performance (CO2 emissions, waste emissions, water usage) of each location and company. We also regularly communicate activity topics and other information to employees through the EcoVision website and email newsletters.
