The Special Type 2 Launch Ka-Mi was the Imperial Japanese Navy's first amphibious tank. The Type 2 Ka-Mi was based on the Imperial Japanese Army's Type 95 Ha-Go light tank with major modifications, and was a capable armoured fighting vehicle on both land and at sea.
As early as 1928, the Japanese Army had been developing and testing amphibious tanks and created several experimental models such as the SR-II, the Type 1 Mi-Sha and the Type 92 A-I-Go which either never made it off the drawing board or were produced only as one-off prototypes for concept testing. In 1940, The Navy took over development of amphibious vehicles and two years later came up with the Type 2 Ka-Mi. The Type 2 Ka-Mi was designed for the Navy's Special Naval Landing Forces for the amphibious invasion of Pacific Islands without adequate port facilities, and for various special operations missions.
Only 184 units of the Type 2 Ka-Mi were built, beginning in 1942, due to the number of complex components and due to the fact that it had to be nearly completely hand-built.
