It is the first tank that was mass-produced in Japan. It was influenced by Vikers C, but its design is utterly original. The model Ko had a gasoline engine and and the model Otsu had a diesel engine.

This tank was used for infantry support mainly in China before WWII, but some were also used in the Philippines during WWII.
