Coexisting with Nature and Conserving Biodiversity
Modern society is maintained by receiving a variety of ecosystem “services” from nature, including circulation and regeneration of materials in the atmosphere, water, and soil.
Based on our Basic Environmental Policy, the Tsubaki Group is reducing its environmental impact through products and manufacturing that are in harmony with the global environment. At Group companies in Japan and overseas, we are also actively participating in the greening of business sites and regional environmental conservation efforts.
Going forward, we will promote these activities and contribute to preserving biodiversity and realizing a society that coexists with nature.
Greening Initiatives in Factories
The Group is focused on expanding green areas and environmental facilities at our 11 business sites in Japan. The “greening rate” based on the area of green space and the “total greening rate” based on the area of green space plus the area related to environmental facilities are shown in the table below, as of May 31, 2025.

Examples of Activities at Overseas Group Companies
Tsubaki Kabelschlepp GmbH (TKG, Germany)
TKG is carrying out initiatives that combine maintaining biodiversity with the welfare of employees. The company regenerated 5,100 m2 of land that was impacted during the construction of the TKG premises. It created a “grassland area of wilderness” by planting grassy areas filled with fruits trees and other plants and creating ponds, as well as setting up a rooftop garden. And it even set up beehives in the grassland area, which have become homes for about 160,000 bees. There are also benches and walking paths in the grassland area, making it a pleasant place of rest and relaxation for employees.
Tsubakimoto Automotive (Thailand) Co., Ltd. (TAT)
With the objective of conserving the natural environment, tree planting projects at TAT have been ongoing since FY 2008. They are centered around Chonburi province, Thailand, and about 45,000 trees have been planted to date. These include mangrove and perennial trees, which are suited to the local environment. Around 40 to 50 employees support these projects by participating each year.
