About the INOAC group

The INOAC Group began in 1926 as Inoue Rubber Co. (now Inoue Rubber Co., Ltd.). In 1954 it introduced urethane foam technology through a technical tie-up with the German company Bayer AG, becoming the first company in Japan to successfully produce urethane foam. The Group has continued since then to develop a variety of new materials, and has expanded its business across a broad spectrum, ranging from household products to automobiles and high-tech.

The Group also has a long history of business overseas, beginning from exports of inner tubes in 1933 and constructing its first overseas plant in Sri Lanka in 1959, till now it operates some 60 production sites in 14 countries and territories. The networks and partnerships that the Group has built up with people in those countries and territories over the span of more than half a century have become an important asset for the INOAC Group. It is no exaggeration to call INOAC a company nurtured by these numerous partnerships worldwide. We will continue supporting the development of global human resources who can shine on the world stage through INOAC International Education and Scholarship Foundation.
