Hikawa Maru
When Japan surrendered on 15 August "Hikawa Maru" was one of only two Japanese large passenger ships to have survived the war. The other was another hospital ship, "Osaka Shosen Kaisha"s "Takasago Maru". "Hie Maru" and "Heian Maru" had been converted into submarine depot ships and were attacked and sunk in 1943 and '44.
