Yokohama Rubber assigns departmental representatives to dual roles within the Compliance Promotion Office to ensure effective compliance management.
These representatives are responsible for workplace education and awareness. Furthermore, they provide the Compliance Promotion Office with monthly reports on compliance status across various risk areas—ranging from interpersonal issues like harassment and information management to labor hours, health and safety, and antitrust compliance.
Through this process, the Compliance Promotion Office monitors the status of each department and implements corrective actions and measures to prevent recurrence whenever concerns or risks are identified.
The same framework is applied across our domestic and overseas Group companies, where Compliance Promotion Officers have been assigned to lead these activities.

We conduct an annual operational audit by our Audit Office. This audit covers 11 areas, ranging from accounting to safety, environment, industrial waste management, and our code of conduct and compliance. We use audit procedures based on our rules and guidelines to ensure that operations are conducted in accordance with these standards. We then issue recommendations and suggestions for improvement, aiming to prevent irregularities and errors. In fiscal year 2023, we conducted audits at 20 locations and issued 495 recommendations and suggestions.

We conduct compliance trainings using topics such as past company compliance issues and socially problematic matters. We categorize the content into general topics intended for broad employee awareness and specific topics for particular departments or positions. We also customize delivery methods by utilizing material distribution, workplace group learning, and group training sessions.
In 2024, we continued training related to harassment and quality fraud, and focused on topics such as mental health, management of appropriate work hours, and handling of entertainment expenses.

The Yokohama Rubber Group Code of Conduct declares the following;
We will not only comply with laws and regulations but also with social norms.
We will not engage in any act that violates competition laws, bribery, or any act that deviates from the law or business practices.
We will maintain sound relationships with political and administrative entities, both inside and outside the country, and will not engage in bribery.
We do not entertain, give gifts or give money to our business partners for the purpose of gaining unfair advantage.
It refers to actions against business partners as well as public officials.
The Anti-Bribery Policy also prohibits the act of bribery for the following "officers and employees of a private company subject to commercial bribery, and any other person who may be a guest of any bribery offense".
Furthermore, regarding the approval procedures for delicate transactions (gifts, entertainment, etc.), we are processing these in accordance with the "Points to Note When Disbursing Funds, etc." and "Points to Note When Receiving Funds, etc." sections of this policy.
We are working to ensure compliance through awareness and education of Yokohama Rubber Group members, and through the CSR Procurement Guidelines for third-party suppliers.
The global whistleblower system is designed to provide an external point of contact to prevent "bribery" as well as "competition law violations" from occurring as quickly as possible.
To ensure the effectiveness of the system, we are making every effort to educate all employees at planned subsidiaries overseas prior to implementation.
In Indonesia, where the system was introduced in 2024, we also conducted training for all employees.

We strictly manage employees’ personal information by obtaining prior consent by quoting the purpose of its usage. We understand the importance of employees’ personal information and ensure its proper treatment; we also let our employees know, through our internal intranet, that we continue to take measures to protect their personal information.
