Environmental Management
The Tokyo Seimitsu Group contributes to the realization of a sustainable society based on the Group’s Basic Environmental Philosophy, which is “Recognizing environmental conservation as an important theme common to all humankind, Tokyo Seimitsu makes environmental conservation an integral element of all product development, design, manufacturing and service activities.”
Basic Environmental Policy
In all business activities, extending from manufacturing products such as semiconductor manufacturing equipment and precision measuring instruments through the provision of services, everyone at Tokyo Seimitsu must always work with the consideration for “Is this action friendly for the earth?” The goal is to reduce our impact on the earth’s environment to the absolute minimum.
Environmental Policy
1.
We will resolutely drive environmental conservation activities by organizing an environmental management structure having “the Environmental Management Committee” as the top, in which all managers play the key role.
2.
We will comply with environmental laws, ordinances and agreements as well as “the Environmental Policy” and establish voluntary goals to grapple with pollution prevention and environmental conservation.
3.
We will strive to develop and improve environmentally responsible products (products contributing to energy and resource conservation, products that do not use harmful substances).
4.
We will establish environmental objectives for the following items concerning the environmental impacts caused by business activities and improve environmental performance by implementing continuous improvement and reviewing the activities by internal audit.
1) Effective use of natural resources by energy conservation, resource conservation and reduction and recycling of wastes
2) Proper management of harmful substances, reduction in their use and the adoption of replacements
3) Prevention of the global warming through the emission control of the greenhouse gas
5.
We will conduct training programs for all employees to raise awareness of environmental protection. Also, we will ask for the understanding and cooperation of suppliers in environmental conservation.
6.
We will make efforts for environmental conservation activities, including use of sustainable resources, mitigation of climate changes and conservation of biodiversity, through individual business operations, strive to achieve a better global environment and contribute to the development of society.
7.
The environmental management system applies to the activities, products, services and environmental conservation activities of the plants relating to the business activities of Semiconductor Company and Metrology Company.
8.
This environmental policy is disclosed internally and externally.
Three Approaches to Environmental Management
Since obtaining ISO 14001 certification in 1998, we have been promoting initiatives to address environmental issues through approaches that are in line with ISO 14001 policies. Through our products and business activities, we aim to reduce our electricity usage and CO₂ emissions, promote resource conservation, control waste generation and total chemical substance emissions, and contribute to the achievement of a sustainable society.
Eco-Factory
As a manufacturing company, more than 99% of our CO₂ emissions come from the electricity used in our factories, and almost all of the environmental impact (water resources, waste generation, etc.) that we cause is from factory operations. Therefore, each plant leads our activities to reduce environmental impact.

Eco-Products
In addition to conducting an LCA*¹ as a mandatory task during new product development screening, we also evaluate the environmental impact of conventional products. We have established “eco-products” as products that are developed, manufactured, and improved according to LCAs and promote activities that reduce environmental impact through related to our products.
*¹ Life Cycle Assessment (LCA)
An assessment method that follows calculation standards for converting emissions to CO₂ at every stage from raw material procurement/product manufacturing to disposal

Eco-Mindset
Tokyo Seimitsu has positioned “eco-mindset” as an initiative to raise the environmental awareness of our employees. By actively providing opportunities for employees to participate in social contribution activities in their daily lives and workplaces, such as the introduction of volunteer activities*² in the training of new employees, we contribute to society through our business activities and take action to solve issues.
*² Volunteer activities
Hachioji “Adopt-A-Road Program” activities, Nakanuki Park cleanup activity, eco-partner agreements, etc.

Environmental Management System
The Company has created an Environmental Management System (EMS) which conforms to ISO 14001. Each Environmental Subcommittee, established as part of the Semiconductor Company and Metrology Company, conducts and evaluates an annual survey of environmental aspects of the organization, products, services, and facilities in accordance with the Environmental Monitoring and Measurement Management Regulations. We prepare, approve, implement, evaluate, and report on our “Environmental Objectives Implementation Plan” and “Environmental Management System Programs” based on legal requirements, our Environmental Policy, and stakeholder requirements.
In addition, while internal audits are conducted twice a year to check the management status of facilities and equipment, the Environment Management Committee confirms that environmental standards are being properly observed, and notifications and reports are appropriately performed. In fiscal 2024, a certification body conducted certification inspections for recertification, including on the Hanno Plant that was completed in July 2023. These inspections have confirmed compliance with the requirements set forth in ISO 14001:2015, including adaptation to climate change (Amendment: February 2024), and that management effectiveness is maintained.
Furthermore, the Furudono Plant, to which some business operations have been transferred from Accretech Powertro System Co., Ltd., maintains its certification status as it was inspected by the same certification body. Going forward, we will seek to have all of our facilities certified, including the Furudono Plant.
Environmental Management Structure（As of March 31st, 2026）
Dissemination of Legal and Environmental Regulatory Information
Each Environmental Subcommittee, established as part of the Semiconductor Company and Metrology Company, delivers legal and environmental regulatory information* from the given company Environmental Secretariat to members of the related Environmental Subcommittee and explains key points. In addition, an environmental internal audit is conducted twice a year to check the laws and regulations that divisions are required to follow as well as level of compliance.
* Main types of legal and environmental regulatory information handled by the Environment Subcommittee in fiscal 2025
Environmental Objectives Implementation Plan/Environmental Management System Programs
The divisions affiliated with each Environmental Subcommittee prepare an Environmental Objectives Implementation Plan that specifies the details of efforts, deadlines, and evaluation methods to achieve the environmental targets of the Semiconductor Company and Metrology Company. Based on this plan, they prepare Environmental Management System Programs that provide annual implementation plan and progress information.
The Environmental Management System Programs for fiscal 2025 were planned mainly to reduce environmental impact by increasing productivity, in addition to implementing energy conservation measures involved in equipment upgrade, operational improvement, and maintenance. The programs were also aimed at reducing packaging materials and prioritizing the use of electric vehicles (EVs). The results of the programs are reported every three months to the heads of relevant divisions and persons responsible for environmental management. In fiscal 2025, we planned programs for 68 items and reached our targets for 62 items (achievement rate of 91.2%).
