Fair Operating Practices



In order for Yokohama Rubber to be a company that continues providing value to society, partnerships with suppliers based on strong trust relationships are essential. In addition, the scope of corporate social responsibility has expanded to not only include one’s own company, but also suppliers for the procurement of raw materials, goods, and services required for business activities, and we believe that it is necessary for Yokohama Rubber to promote CSR that improves corporate value for suppliers so that it is a win-win relationship for both companies. In particular, because there are suppliers from emerging and developing countries in the upstream of the supply chain for our business, we also recognize the importance of assessment from a social and environmental perspective.
This stance is declared in the Basic Procurement Policy, and the actions that should be taken by employees are stipulated in the Yokohama Rubber Group Action Guidelines.

Message from a manager

The Yokohama Rubber Group’s Procurement Policy is “to build relationships of trust based on equitable and fair trade in its aim for co-existence, prosperity, and mutual development” and to select suppliers based on economical reasonability under consideration of comprehensive perspectives; their quality, price, stable supply, ability for technology development, and consideration to the environment, human rights, and occupational safety and health. We believe that true CSR consists of expanding business with suppliers that can understand and support our policies in the areas near our production bases and working towards co-prosperity with the region rather than as a single company. We hold Supplier Study Meetings.

Indirect Materials Procurement Department, Global Procurement Division

Vision for FY 2023

  • We will further collaborate with the procurement departments of our overseas subsidiaries to promote and expand CSR activities that are unified across the YRC Group.

Grievance Mechanisms for Impacts on Society

In Japan, the Compliance Promotion Department has established two contact points, which it calls the "Corporate Compliance Hotline" and the "General Counseling Room”. In addition, a "Compliance Promotion Manager" has been assigned to every division and affiliated subsidiary. The Compliance Promotion Manager absorbs complaints and consultations from constituents.
In February 2018, the Global Whistle-blower System was successively introduced at overseas bases, starting in Asia.
The Compliance Officers in procurement and sales departments gather complaints and inquiries from suppliers concerning business transactions through the CSR procurement contact point and other organizations.
Complaints concerning social impact are jointly resolved by the Corporate Compliance Department, Legal Department and HR departments in addition to the responsible department.
The Corporate Compliance Department confirms the facts related to the consultation by the whistle-blower. The necessary measures are taken in consultation with the procurement departments and sale & marketing departments.
The results are directly reported to the whistle-blower if they have disclosed their name. Reminders are issued within the company as necessary if the whistle-blower is anonymous.
Please see “Compliance”.
