In recent years the demands of the market have become increasingly high. At the same time, companies have been looking for new directions in areas such as the environment.

Naigai Rubber was established in 1913, and thanks to some foresight cornered the domestic market in automobile tires. Since then, we have been trusted as a pioneer in the rubber industry, and in careful accordance with the needs of the time, we have expanded to produce tire tubes, industrial products, sports gear, shoes, and other footwear. The high quality of our products, their ease of use, and their excellent performance... those special qualities which our customers have experienced are the result of many years of work. But not content to rest on our laurels, we stress our skill, experience, and reliability, and work towards even better results, while playing a useful part in society.

While harking to the call of this era of increasing speed and diversification, we wish to offer extremely reliable high added-value products, in order to make our contribution to society.
