Akitsu Maru (あきつ丸?) was a Japanese landing craft depot ship and escort aircraft carrier operated by the Imperial Japanese Army. In some sources Akitsu Maru and her sister ship Nigitsu Maru (にぎつ丸?) are also considered to be the first amphibious assault ships.
Akitsu Maru was a passenger liner taken over before completion by the Imperial Japanese Army. The ship was fitted with a flight deck above the hull, but had no hangar so the aircraft were stored below the flight deck on the original main deck. Conventional aircraft were able to fly off from her deck but could not land aboard due to the short deck length and lack of landing mechanisms. The Kokusai Ki-76 and Kayaba Ka-1 were flown off Akitsu Maru, as the former was a small, slow aircraft that could land on its short deck and the latter was an autogyro which could even more easily land on a short deck without assistance. She could also carry 27 Daihatsu class landing craft.
Akitsu Maru's planned role was to provide aircover during amphibious and landing operations; in practice the ship and her sister ship the Nigitsu Maru were essentially aircraft ferries.
On Thursday 18 November 1943 Akitsu Maru, while in company with large torpedo boat Tomozuru, was torpedoed off the entrance to Manila Bay by the United States submarine Crevalle (SS-291). The Crevalle incorrectly reported the Akitsu Maru as sunk.
The Akitsu Maru was sunk by the submarine Queenfish (SS-393) on 15 November 1944. There were 2,046 men, mainly of the IJA's 64th Infantry Regiment, who were killed. Her sister ship Nigitsu Maru was sunk by the submarine Hake (SS-256) on 12 January 1944, with the loss of 574 men.
