Tsushima Maru (対馬丸) was a Japanese passenger/cargo ship that was sunk by the submarine USS Bowfin during World War II, while carrying hundreds of schoolchildren from Okinawa to Kagoshima. On August 22, 1944, at between 10:00 p.m. and 10:30 p.m. local time, Bowfin attacked the convoy in which the Tsushima Maru was sailing and sank her, close to the island of Akusekijima.[3] 1,484 civilians, including 767 schoolchildren, were killed. 59 children survived the sinking.
