Environmental management


Fundamental environmental policy

At Hamamatsu Photonics K.K., we've formulated a "Fundamental Environmental Policy" as a companywide policy, and are actively involved in environmental management activities.


Hamamatsu Photonics, as a company that contributes to society through photonics technology, aims to realize a sustainable society toward a future with balance among all forms of life, whilst considering the importance to harmonize environment with society and economy.


  1. Providing environmentally friendly products
    Manage chemical substances contained in products, as well as develop and provide products that contribute to environmental improvement and reduce the burden throughout the product life cycle.
  2. Actions to address environmental activities
    Encourage all our employees to take environmentally friendly actions, achieving our environmental goals based on the identification of risks and opportunities that can influence our business activities, products and services.
  3. Protection of the environment, prevention of pollution
    Address energy saving, global warming prevention, waste reduction, sustainable resource use, chemical management, biodiversity protection, conserving water and preventing pollution.
  4. Compliance of environmental regulations
    Comply with domestic and international legal requirements, individual agreements and other requirements to which we subscribe voluntary.
  5. Continual improvement of environmental management system
    Make efforts to improve our environmental performance by the continual improvement of our environmental management system, through the evaluation of the environmental impact at regular intervals.
  6. Promoting environmental communication
    Promote environmental consciousness and friendly communication with stakeholders and our employees by widely disclosing environmental information both internally and externally.

Environmental management system

Under the Hamamatsu Photonics Fundamental Environmental Policy, each fiscal year we set environmental goals and targets for our environmental management system(EMS), we evaluate the results from our activity, and work to constantly improve our EMS on the basis of management review.

To ensure that the cycle described above runs smoothly, we have established a Headquarters Environmental Committee, the decision-making body of the EMS chaired by the General Environmental Management Representative (environmental management executive officer) under the Sustainability Management Committee. This Committee is an umbrella group composed of the five environmental working groups, the environmental committees in each business domain, and the Headquarters Environmental Committee Secretariats. By establishing similar structures in each business domain, we enable the execution of comprehensive environmental activities.

The environmental working groups and the issues they primarily deal with are listed below.

  • Energy saving working group: Reduction of use of electricity, fuel and other forms of energy; advancement of use of renewable energy; prevention of global warming
  • Waste working group: Appropriate management of waste, “Reduce, Reuse, Recycle” (3R Activities)
  • Chemicals working group: Appropriate management of chemicals, management of shipment and receipt of chemicals
  • Conservation working group: Pollution prevention and other environmental maintenance; maintenance of biodiversity; prevention of global warming
  • Product assessment working group: Advancement of environment-friendly and environmentally contributing products; management of chemicals included in products; green procurement

Certification under ISO 14001

Every business location of Hamamatsu Photonics is certified under ISO 14001:2015 and is striving to maintain and improve its environmental performance. To deepen each employee’s understanding of the EMS, Hamamatsu Photonics conducts a wide range of employee training programs, including new-employee training, internal-auditor training and specialist environmental training.


The Company also conducts annual environmental internal audits. Through these audits, all employees work together to improve the EMS, not only identifying failing processes but also optimizing operation through pointing out areas for possible improvement, and sharing information.


Today ISO 14001 certification covers 100 % of Hamamatsu Photonics on a production-site basis and 98.1 % of the Company on an employee basis.

Hamamatsu Photonics is planning to expand the range of certification.

Compliance with environmental laws and regulations

Hamamatsu Photonics works hard to prevent pollution of the living environment in all forms, including air, water, noise, soil and odor pollution. We also strive to reduce our environmental impact and manage waste responsibly. On a regular basis, the Company measures and analyzes outputs such as wastewater, noise and vibration, and conducts on-site inspection of its waste-disposal contractors. When problems are discovered, we take appropriate measures and takes every precaution to ensure that it complies strictly with environmental laws and regulations. At the meetings of the Headquarters Conservation Working Group and Headquarters Waste Working Group, we observe environmental preservation facilities and the status of waste management at each business location.

There were no violations of environmental laws and regulations, environment-related fines or major environmental accidents at Hamamatsu Photonics during the period under review.
