It had quite extensive armor protection (from 10 to 50 mm/0.4-1.97 in), it was fitted with a 47 mm (1.85 in) Type 1 gun in the casemate, and a secondary 25 mm (0.98 in) AT light gun Type 1 in the turret, plus two Type 97 machine guns. It weighed 29.1 tons but was slow at 32 km/h (20 mph) on land and 10 km/h (6 mph) on water.

Design

The Type 5 To-Ku was essentially on the same vein as the previous Japanese amphibious tanks, such as the Type 2 Ka-Mi, and the Type 3 Ka-Chi. There was a central hull on which 2 pontoons were added to the bow and rear.

In total, the To-Ku was 35.4 feet long for 11.8 in width and 12.7 in height. It was assembled with welded rolled homogeneous steel plates, 10 to 50 mm (0.4-2 in) in thickness. Total weight, battle ready was 29.1 short tons, for a crew of 5 (driver, commander, gunner, loader, hull gunner/radio operator).

Propulsion was assured by a Water-cooled 12-cylinder Mitsubishi diesel, 240 hp and 8 hp/ton, for a top speed of 32 km/h (20 mph) on land and 10 km/h (6 mph) on water. The drivetrain comprised four bogies with four doubled road wheels each, suspended by Bell cranks.

The turret of the To-Ku was modified from the Chi-Ha Kai. This carried a 25 mm (0.9 in) Type 1 gun, and 2 x 7.7 mm type 97 (0.3 in) machine-guns. The Tank’s main armament was a 47 mm (1.85 in) gun, mounted in the forward hull. The Type 5 To-Ku never saw service.
