Akitsu Maru (あきつ丸?) was a Japanese landing craft depot ship and escort aircraft carrier operated by the Imperial Japanese Army (IJA). 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. Contrary to many secondary sources, the Nigitsu Maru was not fitted with a flight deck.
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. Although, in July 1944, KX arresting gear was fitted on the flight deck. 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 was essentially an aircraft ferry.
On Thursday 18 November 1943 Akitsu Maru, while in company with the torpedo boat Tomozuru, was torpedoed off the entrance to Manila Bay by the United States submarine Crevalle. Crevalle incorrectly reported Akitsu Maru as sunk.
Akitsu Maru was sunk by the United States submarine Queenfish 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 on 12 January 1944, with the loss of 574 men.
