Japanese submarines in the Pacific War consisted of 169 boats of the Imperial Japanese Navy. During the war Japanese submarines sunk two US aircraft carriers, a cruiser and numerous other warships. Later they became used to resupply isolated island garrisons. The Japanese began the war with an advanced submarine torpedo design, the Type 95.

I-402, was one of three completed Sen Toku I-400 class submarine aircraft carriers of the Imperial Japanese Navy. These submarines were the largest built prior to nuclear submarine development. Each were able to carry three Aichi M6A Seiran floatplanes.In 1942, 18 of these vessels were planned intended for attacks on the eastern seaboard of the United States and the eastern locks of the Panama Canal. However after increased shipping losses and the rising scarcity of alloys, only five were expected to be built. By 1944, only three had been completed (I-400 at Kure, I-401 and I-402 at Sasebo).Entering service late in the war, I-402 never saw combat and was captured by the US at the end of the war.
