Our goal is to continually manufacture products that will be needed and trusted in any era.
A business with over 70 years experience in manufacturing outsole and insole materials for Japan-made shoes, our track record of providing materials and unique compounding technology has culminated in the development of insoles for medical use.
Now to go even further, we have concentrated all our knowledge and expertise into one to create the buntaro® brand.
History of buntaro®
We were established in 1948, soon after World War II, in Nagata-ku, Kobe, the birthplace of the rubber industry in Japan.
Today, Nagata is known as a production center for fashion shoes, but its history began after the war as a major production center of rubber shoes, protecting the feet of Japanese people from the burnt-out areas all over Japan.
A major turning point in the company’s history came in 1951 with the invention of the independent foam rubber sponge.
With this invention, which greatly expanded the possibilities of rubber by making it lightweight, waterproof, and cushioning, Nagata grew to become one of Japan’s leading producers of rubber products and the largest footwear industry region in Japan.
In the midst of this history, through the production of rubber shoes, we have been providing materials for over 70 years as a manufacturer of outsole and insole materials for Japan-made shoes.
