History of Toyoda Gosei

Product history

The origins of Toyoda Gosei date back to the rubber research department established in Toyoda Automatic Loom Works in 1934. The aim was to manufacture retreaded tires for a move into the automotive industry by Kiichiro Toyoda, the eldest son of world-renowned inventor Sakichi Toyoda and the founder of Toyota Motor Company. During World War II, the business was integrated into Kokka Kogyo and moved to the plant of the former Kikui Shokufu, becoming Kokka Kogyo’s Nagoya Plant. After the war, the main operations of Kokka Kogyo were separated into independent companies. At the decision of Kiichiro, the Nagoya Plant also become independent in 1949, starting out as Nagoya Rubber.
