Yamaichi’s Sustainability

Basic Sustainability Policy

Leveraging the dynamic technological capabilities and imaginative powers developed since its founding, the Yamaichi Electronics Group has always responded to the current requirements of its customers. Moving forward, we will further broaden our commitment to sustainability as we collaborate with stakeholders to establish sustainable societies and build a better future.

In pursuit of these goals, we will apply the principles of our management philosophy (“People: Our most Important Assets”, “Create Value”, “Commitment to Quality”, “Technology Innovation Makes a Difference” and “Contribution to Communities and the Environment”) to create a beneficial, self-perpetuating, and social value creating cycle through which we enhance the economic values of our products by providing technologies that facilitate the resolution of social issues.

Yamaichi Electronics Group will continue contributing to a sustainable future by ambitiously establishing strong connections between people, companies, society, and the Earth.

Sustainability Promotion System

In March 2023, we established the Sustainability Committee, which is chaired by the President.
The Sustainability Committee deliberates on issues such as tackling climate change, and the committee has a system for reporting its decisions to the Board of Directors.

In order to manage whether we are steadily fulfilling our targets, the Sustainability Committee will play a central role in working toward achieving these targets when there is a discrepancy between targets and actual values, or when there is room for improvement.

Sustainability Management

Through our Test Solution Business, Connector Solution Business, and Optical-related Business, we aim to integrate financial and non-financial strategies by contributing to solving social issues and conducting corporate activities based on ESG. The Sustainability Committee will play a central role in setting targets and indicators for materiality (priority issues).
