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 and CSR and Environment Contribution Awards as part of our aim to conduct CSR activities together.
