Environmental Management

Acquisition of ISO 14001 certification

In order to properly operate environmental management, the Group has acquired ISO 14001 certification for each department and has constructed an “Environmental Management System.”

Each plant carries out environmental activities for continuous improvement based on the Environmental Management System.

  • *Plants that have acquired ISO 14001: Sagamihara Plant, Tochigi Plant, Hiroshima Plant, Gifu Plant, Topre Kyushu (Kurume Plant), overseas plants

Environmental Audits

Our Environmental Management System is subject to regular internal audits at plants and external audits by certification/registration bodies. If items are pointed out by the audits, the cause(s) and countermeasures(s) are established and prompt corrective action is taken. Our internal auditors also conduct systematic education and pursue high-quality audits.

Environmental Management Review

In order to ensure continuous improvement, appropriateness, validity, and effectiveness of the Environmental Management System, it is regularly reviewed by the top management of the plants.

Implementation of Environmental Improvement Committee

The Environmental Improvement Committee meets once a month to discuss, develop, and report on the environmental activities of each department, and to continuously improve environmental conservation activities.


Each plant regularly evaluates and reports on the status of compliance with environmental laws and checks that there are no violations. Furthermore, the Sagamihara Environmental Secretariat conducts regular audits regarding the compliance status of each plant.

Waste management

The waste generated from each plant is thoroughly sorted and properly treated to preserve the environment and improve the public’s health, as well as to carry out resource recycling and reduction of waste.

Management of chemical substances

Regarding newly purchased substances, we ask the environmental management department to evaluate the intended use, toxicity, and amount of use of the chemical substances, and we carry out reliable management with a purchasing system after the evaluations are completed.


Self-awareness education

We educate all employees about global environmental issues, the outline of ISO 14001, our environmental policy and environmental improvement plan, and the environmental impact of the people in charge of each department.

Responding to emergencies

Each department has established procedures for the prevention and mitigation of environmental impacts in the case of an emergency as necessary, and conduct training once a year.
