The Type 1 experimental design led to the Type 2 Ka-Mi, which was based on the Type 95 Ha-Go light tank chassis. The Type 2 Ka-Mi was the first production Japanese amphibious tank, although beginning in 1942 only 182 to 184 units were built. The Type 2 Ka-Mi was first used in combat on Guadalcanal. Later they were encountered by US forces in fighting on the Marshall Islands, and Mariana Islands; particularly on Saipan where they supported the Yokosuka Base Special Naval Landing Forces in its failed amphibious operation. They were also used to support the SNLF during the fighting on the Philippine island of Leyte in late 1944.
