The “Ka Mi” was the first amphibious tank used by the Imperial Japanese Navy (IJN), and it was based on the Type 95 “Ha-Go”light tank. It was designed for Japanese landing forces performing amphibious invasions of Pacific islands and regular port facilities. Production of the Type 2 commenced in 1942 and a total of 184 amphibious tanks were made, although the design was too late to participate in Japan’s island-hopping campaign. When used in water, large pontoons were attached to the glacis plate and rear deck to give it a top speed of 10km/h in water. These pontoons could be shed as soon as the vehicle reached land.
