The adapted mountain gun, known as the Type 99 7.5 cm Tank Gun, was completed in 1940. By 1942, with the start of World War II, the Japanese army began to encounter the Allied M4 Sherman and M3 Stuart tanks, which they could barely cope with. The design parameters on the Type 2 were then changed to include a tank destroyer role, with its 75 mm gun equipped with armor-piercing shells.
The Type 2 Ho-I utilized the chassis of the Type 1 Chi-He, which was itself a modified Type 97 Chi-Ha.
Production was hampered by material shortages, and by the bombing of Japan in World War II. All thirty existing Type 2 Ho-Is were conversions from existing Type 1 Chi He medium tanks. The Tokyo factory of Mitsubishi Heavy Industries was unable to retool for mass production by the end of 1944, when the program was cancelled. These units were allocated to the Japanese home islands to defend against the projected Allied Invasion. As the cessation occurred before that invasion, the Type 2 Ho-I never saw combat.
