The Type 2 Ho-I gun tank was designed to provide Japanese tank regiments with a close support weapon to fight alongside the improved Chi-ha medium tanks. These tanks carried a 47mm anti-tank gun, which was a distinct improvement on the earlier 57mm gun in the anti-tank role, but less effective when firing HE shells.
The prototype of the Type 2 Ho-I was built on a Chi-ha medium tank, and saw the 75mm Type 99 L/23 cannon replace the 47mm gun. This gun fired a 6.6kg/ 14.5lb high explosive shell, with a muzzle velocity of 445mps.
A small number of Ho-Is were produced, all of them by converting existing Chi-he medium tanks to carry the new turret. The Type 2 Ho-I does not appear to have been used in combat.
