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, USS Bowfin attacked the convoy in which Tsushima Maru was sailing and sank her, close to the island of Akusekijima.[3][4] Tsushima Maru Commemoration Association Survey Data (As of August 27, 2005), reported a total of 1,661 civilian evacuees, including 834 schoolchildren (of which 775 were killed and approximately 59 survived the sinking).[5] Shortly after the sinking a "gag order" was enforced and families and survivors rarely spoke about the incident. The number of victims that have been identified by name, based on notifications from bereaved families (As of August 22, 2012), include 780 schoolchildren.[6]

The ship was part of Convoy Namo 103, which consisted of the following ships:[4]

  • Tsushima Maru (passenger / cargo vessel)
  • Kazuura Maru (listed as Waura Maru in some sources, assumed to be a cargo vessel)
  • Gyōkū Maru (cargo vessel)
  • Destroyer Hasu (Momi class)
  • Gunboat Uji

Its wreck was located and identified in December 1997.
