Message from the President
Tomoyuki Okuno
Suzhou is famous for its rice, tea and freshwater crabs, known as Shanghai crabs in Japan, as well as its abundance of fish. Thus, many people from Japan also come here on sightseeing tours.
The plant began operations in 2008 as a truck and bus tire plant and added passenger car tire production in 2014.
In 2017, the TB factory finished producing tires for trucks and buses, and has since been renovated into a tire factory for passenger cars.
Since then, we have continued to improve our production capacity, reaching 20,000 bottles per day in 2023.
As a result, the cumulative production of passenger car tires has reached 27 million units as of the end of 2023.
Our goal is to be a company that coexists in harmony with the local community by engaging in activities that contribute to the local community and take root in the community in this rich land. On the other hand, due to its affluent location, it is highly sensitive to the environment and its regulations are much higher than Japan's. Environmental measures for odors and VOCs are required at a high level. In addition, we will continue to participate in the release of fry into the lake, continue our tree planting activities in the Forever Forest, and promote biodiversity activities in the region.
Through our health and safety activities, we will help our employees feel that their safety is a family's happiness, and all of us will strive to become a company that is admired and trusted by everyone to achieve the goal of "becoming a “company that is attractive to both employees and regional communities.”

Grievance resolution
In 2023, we have significantly improved our environmentally friendly facilities.
