The Ho-Ri I was a more powerful tank destroyer (gun tank) using a 105 mm cannon in place of the 75 mm gun design and an additional 37 mm gun in the front armored plate.
The armor was to be 30 mm thick and it was to have a crew of six.
It used the Type 5 Chi-Ri tank chassis.
The superstructure for the main gun was placed at the rear, the engine was positioned in the center area of the chassis and the driver's station was in the front hull section; all similar in design to the German Ferdinand/Elefant heavy tank destroyer.
According to "The National Institute for Defense Studies, Ministry of Defense, Military Administration of Munitions Mobilization, Production Chart of January to April of 1945", the plan was to produce a total of 5 Ho-Ri gun tanks by March 1945.
However, no prototypes are known to have been completed.
 Another variant of the Ho-Ri was to have a twin 25 mm anti-aircraft gun on top of the rear casemate superstructure in a "swivel mount".

A second version planned was the Ho-Ri II heavy tank destroyer.
It was to use the Type 5 Chi-Ri tank chassis.
The boxy superstructure for the main gun was completely integral with the hull's sides and placed at the center of the chassis (similar in design to the German Jagdtiger).
The engine compartment was moved in the rear area of the chassis.
It also was to use a 105 mm cannon as its main armament.
