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. The plant, which completed production of truck and bus tires at TB plant in 2017 and was renovated to produce passenger car tires, began production in October 2019, and on October 12, 2019, the opening ceremony and the "Forever Forest" tree planting activity were held simultaneously. In addition, by November 2019, the plant will have achieved 10 million passenger car tires, and is expected to have an annual capacity of 4.46 million tires by 2021, including the renovated plant, as it continues to enhance its presence as a passenger car tire production base in China.

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.”

Organizational Governance

Code of Conduct

A Code of Conduct has been drawn up, which is printed on a card (together with the company’s policy) and distributed to all employees.

Workplace communication

Within the company, corporate decision-making is conducted through the holding of key meetings (including management meetings, cost meetings, safety meetings, environmental meetings, quality meetings, meetings of the human resources committee, minister's meeting, section chief's meeting, general manager's meeting and field morning meeting) on a periodic basis.

Human Rights

CSR education

We implement quarterly compliance training for managers of middle level engineer and above. All employees receive compliance training twice a year. Internal control-related education is provided for internal control team members. We publish a quarterly CSR plant magazine to disseminate knowledge on the subject.This year, we added legal education for specialized operations: for example, education on contract risk management, targeting purchasing and finance. We invited outside lawyers to conduct job crime education for personnel at the elementary engineering master level and above in order to ensure that everyone is upholding the law. CSR training has been conducted once/month for managers at the section manager level and above, as well as for worker representatives.

Grievance resolution

Based on the feedback from the government's environmental department, we are not only complying with emission control standards but also reducing the burden on the local community by improving environmental facilities while taking into consideration the local residents.
In 2021, new environmental facilities (RTO facility at Plant No. 2, deodorizing tower at vulcanization environmental facility, etc.) are being introduced to reduce the impact on the surrounding environment. Environmental facility management standards and standard operating procedures have been developed to improve management capabilities. Since this project has had a positive effect, it is being expanded to Plant No. 1.

Noise and emissions

We conduct measurements four a year in accordance with the regulations of the regional government. With respect to all measurements that have been taken thus far, the environmental regulation values on all items fall within the specified scope.

Furthermore, the company is also working to build up a mutual surveillance structure through the organizing of whistle blowing systems and the installation of suggestions boxes, etc.
In 2021, we implemented the second step of internal control operations, organizing work flow, risk identification, and risk improvement in the product warehouse, equipment warehouse, and raw material procurement section. Currently, we have completed 45 levels of risk improvement.

Besides reporting to the relevant company committees all matters relating to revisions in the law, regulations or ordinances, once such has been scrutinized by the Internal Control Office, the company asks its attorneys for legal advice regarding all matters that relate to various contractual obligations or require specialist know-how.
Regularly collect laws related to company management and send them to relevant departments. Ensure compliance with laws during the implementation of each operation.
