Developed under the program for improving the maneuverability of the T-26 light tank through redesigning its chassis to a wheeled caterpillar type. The prototype was built in 1935. The vehicle saw service on February 29, 1936 after a series of modifications. At least four vehicles from the experimental batch underwent trials in 1937, but the production was discontinued due to transmission faults and high cost.

Developed by Mitsubishi from 1935 through 1937. The vehicle was mass-produced from 1938 through 1942, alongside an upgraded Shinhoto Chi-Ha for the last two years, with a total of 1,220 vehicles of both types manufactured. The Chi-Ha and Shinhoto Chi-Ha tanks were widely used by Japanese forces in China, and after Japan capitulation, these vehicles were used by both the PLA and Kuomintang forces in the Civil War of 1946.
