Conserving Water

A large amount of water is used in the semiconductor manufacturing process. Water availability is a global issue, and we continue our efforts to reduce water consumption and give consideration to our impact on local ecosystems.

Water Resource Conservation

In Japan we save water resources by actively recycling and reutilizing water. In 2019, the total amount of water used in our factories in Japan was 23,113 thousand m3, the annual amount of water supplied was 14,783 thousand m3, and the recycling rate was 36.0%.


Yamaguchi Factory: Forests for Conserving Water

The Yamaguchi Prefecture in Japan is working to create a healthy and diverse range of forests in order to demonstrate the multi-faceted, sustainable effects of forests, such as the cultivation of water sources, the prevention of disasters in mountainous area, and the prevention of global warming. In order to support the forests which are shared by the Yamaguchi Prefecture and its inhabitants, the 12th “Activity to Develop Water-Protecting Forests” was held in November 2019 with the aim of promoting voluntary activities by corporations. A total of 199 employees and administrative officials from neighboring companies participated, and 8 employees from our Yamaguchi Factory also took part. In this activity, we prepared forests around the Akiyoshidai Kazokuryoko village, which is located north of our Yamaguchi factory and which is also a source of water for the Atsugashi River, which our factory takes water from for production use.
