This is a really neat one. A big tank for the Japanese and amphibious — although to be amphibious pontoons had to be fitted for and aft. The tank was actually the amphibious version of the Type 95 Ha-Ho with some additional modification. The tank was operated by the Imperial Japanese Navy and interestingly, the only amphibous tank vs amphibious tank battle occurred off the coast at Leyte where several Ka-Mis were destroyed by US LVT-1s — both vehicles having similar armour.
There is a surviving Type 2 Ka-Mi at the Russian Kubinka Tank Museum just outside of Moscow – a place I would like to visit one day, if only to see the only surviving PzKpfw VIII Maus.
