Contributing to a Sustainable Future through the Wonders of Science

In today's world we are required to address a range of social challenges, including combating climate change and creating a society with greater diversity. To meet this requirement, we need to demonstrate creativity and foster innovation for the transformation of society. Based on this recognition, TAIYO YUDEN aims to contribute to solving various social issues and to bettering society through its activities to increase both its economic and social value, the two components of its corporate value.

TAIYO YUDEN has been delivering new value to an always-changing world ever since its founding. We will continue to support the further advancement of leading-edge technologies based on our ability to manufacture high-efficiency and high-quality electronic components, while creating solutions that help people lead secure, comfortable and convenient lives. As a new type of business solution that also contributes to solving social issues, our regenerative electric-assist system helps reduce the environmental impact of electric-assist bicycles by making it possible for the bicycles to be recharged while they are running. As another example, our river monitoring system contributes to disaster control and mitigation through the real-time monitoring of water levels and other conditions.

For TAIYO YUDEN, employees who have diverse characteristics are a source of value creation, but to create such value they must be in good health and provided with opportunities to make meaningful contributions. In order to promote diversity in our workplaces, we set targets for the proportion of women among new graduates hired by the company and in managerial positions. We also regularly conduct an employee engagement survey toward implementing measures to increase employees' interest in and satisfaction with their jobs. TAIYO YUDEN also focuses on the solution of environmental issues and sets its own reduction targets for greenhouse gas (GHG) emissions, waste generation and water consumption. Especially for GHG emissions, with an eye to contributing to the achievement of the so-called 1.5 degrees Celsius target agreed at COP26*, we will further foster our energy conservation and creation measures as well as the use of renewable energy toward the realization of a decarbonized society, while also enhancing the disclosure of related information.

We are intensively conducting these activities as part of our issues of materiality set under the Medium-term Management Plan 2025 by backcasting from 2030. Going forward, TAIYO YUDEN will continue to make contributions to a sustainable future.
