Examples of environmental activities

Climate Change Action Plan

Reducing CO₂ Emissions

We have three initiatives as a base for our plans to reduce CO₂ emissions.
First, we are developing energy-saving solutions that all employees can participate in, starting from our offices. In addition to clarifying and displaying the temperature settings and light-off times for air conditioners and lighting, we are also spreading awareness throughout the company regarding energy conservation. Furthermore, we are creating an energy-saving environment by adopting energy-saving equipment as an option for new installments and renewals of equipment.
The second initiative is aimed at reducing emissions by improving the productivity of production lines. As an example of a particularly successful case this fiscal year, we were able to make a significant improvement in reducing in-process defects by going to the site, making a direct observation, and taking immediate action. As a result, we were able to reduce the amount of waste as well as the amount of energy usage. In addition, activities to improve the operation rate, such as reducing equipment downtime, have eliminated losses from idling and resulted in energy savings.
The third initiative was the introduction of CO₂free green electricity in cooperation with the KITZ Group. We have made significant contribution in the reduction of emissions by using 100% renewable energy.

Examples of social contribution activities

Participation in Lake Suwa cleanup by employee volunteers

In FY2021, six in-house volunteers participated in the Lake Suwa cleanup, which was part of the Adopt Program sponsored by the Japanese Trade Union Confederation of Suwa (RENGO Nagano). In August, 25 employees participated in the KITZ Microfilter Clean Campaign, picking up trash along sidewalks near the office. Participating employees commented that they wanted to protect the environment they live in for the future, and that they were surprised and pleased at the large number of people who participated.

Cooperation in Internships (Work Experience) for Local High School Students

We cooperate with local high schools, junior high schools, and elementary schools in their internship programs. We accepted five students in 2021 and seven students in 2022 for work experience. The students commented that they became interested in manufacturing and gained insight for their future careers. They also said it made them happy to think that the products they worked on would be useful somewhere.
