The Type 5 To-Ku amphibious tank was the biggest of all of Japan’s amphibious tanks. It weighed 29 tons.

Because of its size, it could carry more powerful armament than the Ka-Chi amphibious tank.

The To-Ku mounted a 0.98 inch (25mm) cannon and a coaxial machine gun in the turret.  The front hull contained a 1.85 inch (47mm) gun and an additional machine gun.
