Sinking History
On September 24, 1944 at 9:05am, attacked by thirty US Navy aircraft from Task Force 38 (TF-38) in Coron Bay. Hit by two bombs midship and by 9:15 listed heavily to the starboard. Another bomb hit the stern catapult causing a large explosion of aviation fuel aboard and blew out the port quarter, nearly breaking the ship into two pieces. Soon afterwards, capsized and sunk at roughly 11°59′N 120°02′E. In the sinking, four officers and 82 men were lost.

After the sinking, Minesweeper # 41 and naval transport T-102 rescued Captain Fujimaki, 25 officers, and most of the crew including 25 wounded. Others swim to shore.

On August 25, 1945 salvage teams from USS Chanticleer discovered the wreckage of Akitsushima in Coron Bay at 108' with a 90 degree port list. More wreckage was found to have been blown 50 feet astern.

The shipwreck is located between Culion Island and Busuanga Island, both near Manglet Island. Underwater, the catastrophic damage from the stern explosion is clearly evident with only the keel and plates on the starboard side attaching the stern to the rest of the ship and massive internal damage.

The seaplane crane is intact. The crane is lying on the sandy bottom and attracts schools of giant batfish and barracudas. One mounting of a tripple Type 96 tripple anti-aircraft gun is present at the front of the flying boat tracks.

Due to depth and hazards within the shipwreck, no penetration is allowed without proper certification and supervision. Wreck divers can make an impressive penetration into the engine room to see the ship's four engines. The gears and machinery for operating the crane are the main objects of interest for a penetration into the stern.
