This Japanese feighter was sunk in Apra Harbour on August 27th 1943. She had already been attacked by one US submarine seven months earlier and was resting up when the fatal attack was launched by another submarine.
She is large, at over 135m and lies in 35m of water, listing heavily to port. A tordedo blew a hole in the number 3 port cargo hold and it was this damage that almost certainly sunk her. The holds still contain some interesting relics including beds and truck frames. The engine room is enormous and the two engines and catwalks are intact. The deck house at the stern still contains some depth charges - do not attempt to touch these!
One amazing feature of this site is that the Tokai Maru rests next to the SMS Cormoran, a German merchant raider that was scuttled in 1917. The two ships actually touch and this is the only place in the world where two vessels, from different conflicts, do so.
The Cormoran is 90m in length and lies in 35m of water. The best way to approach her is to follow the midsection of the Tokai Maru until you see the vessel at 22m. The hull is intact and the engine room easily accessable through skylights.
