“Good products come from a good business environment with a commitment to synergy of Quality, Cost and Human Resources”:

This is the guiding principle of Hokusei Rubber Industry. While creating a solid business foundation by incorporating customers’ needs into our products and focusing on the market, we are leading the industry in our sector.


Since its establishment in 1930, Hokusei Rubber Industry had focused on the manufacturing and sales of rubber footwear until 1972, when its core business shifted completely to the manufacturing of industrial rubber products.

We have since emerged as a leading manufacturer of a comprehensive line of industrial rubber products that cater to the automotive and building construction industries as well as to the civil engineering, roadways, and electrical and chemical sectors. In August 1986, a new plant was constructed, and the "Kanban System," which is centered around the Toyota Production System, was introduced to implement an efficient manufacturing system. We remain committed to fulfilling the diverse variety of requests from our customers.

We aim to scale new heights by strongly promoting quality control and pursuing a sounder management structure.

Our goal is to "contribute to society by offering high-quality products." We will continue striving to become better taking this as the guiding principle. Thank you for your support.

Policy on Procurement of Conflict Minerals

We are concerned that the mineral resources mined in the Democratic Republic of the Congo (DRC) and its nine neighboring countries may be being used to fund the armed forces in the area, leading to human rights violations and environmental destruction. To avoid such tragedies, we are working with our customers and suppliers to review our supply chain to identify anomalous suppliers, so as to ensure that our procurement activities do not result in the acquisition of minerals in support of any armed force.
