A 6,886-ton freighter, Arisan Maru was one of Imperial Japan's World War II hell ships. The hell ships were floating prisoner of war (POW) camps used to move them and to use the POWs as human shields.

On October 24, 1944, Arisan Maru was transporting 1,781 US and Allied military and civilian POWs when she was hit by a torpedo from an American submarine (either USS Shark or USS Snook), at about 5 p.m.; finally sinking at about 7 p.m.

No POWs were killed by the torpedo strikes and nearly all were able to leave the ship's hold, but the Japanese did not rescue any of the POWs. Only nine of the prisoners aboard survived the event.
