Atago Maru was a merchant ship built prior to World War II in Glasgow in 1924 by Lithgows & Sons for Nippon Yusen. One of the first diesel-engined cargo ships in service in Japan, Atago Maru was converted to an oil tanker in 1942. Returning to service in 1943, the ship saw extensive service traveling in convoys during World War II. On 28 November 1944, the vessel was bombed by a United States Army Air Forces bomber while at anchor off Borneo. The shipwreck is a popular diving site in Malaysia.
