1920s - 1950s :

Komatsu Iron Works was established by Takeuchi Mining Industry as a subsidiary to make industrial tools for the parent company. Komatsu ultimately developed into large enough to sell to the public, and was spun off on May 13, 1921 as Komatsu Ltd.

In 1924, Komatsu built its first press, a 450-ton sheet-forming press. Komatsu manufactured its first agricultural tractor prototype in 1931. Through the 1930s, Komatsu also manufactured military tractors for the Japanese military, as well as bulldozers, tanks and howitzers. It began production of its first diesel engine in 1949. Its growth as a company was aided by the strong demand for its bulldozers during Japan's post-war reconstruction in the 1950s.
