Developed by the ČKD company for the Czechoslovakian Army in 1938. During the German occupation, the vehicle saw service in the Wehrmacht and was used in the Polish and French Campaigns, as well as on the Eastern Front. The tank saw combat on the front line until the middle of 1942. Approximately 1,400 vehicles in eight modifications (Ausf. A/B/C/D/E/F/S/G) were manufactured.

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.

A further modification of the Ha-Go developed by Hino Jidosha Kogyo. Despite the improved dynamic characteristics, the tank did not replace the Ha-Go. About 100 tanks were manufactured by Mitsubishi and Hino.
