Kizugawa Maru

On April 8, 1944, she was part of a supply convoy from Saipan to the garrison at Woleai,[4] when she was damaged in the port engine room[5] by a torpedo attack by USS Seahorse about 47 kilometres (29 mi) off the eastern coast of Guam at 13°16′N 145°11′E / 13.267°N 145.183°E / 13.267; 145.183.

[4][2] Due to her engine room flooding quickly, she sank straight down and sits upright in northern Apra Harbor.

[10] In 2007, researchers noted a large concrete block had crashed through the bow deck structure, apparently due to an mooring accident.

Due to the depth, recreational divers use Nitrox or are severely limited on the time available at the gun or deck in order to avoid incurring a decompression obligation.

[10] Trained wreck divers considering penetration are further cautioned about plentiful silt, as well as twisted metal around the engine room and holds.
