The Tenyo Maru was a 6,843 gross ton passenger cargo ship built by Mitsubishi, Nagasaki for Toyo Kisen Kabushiki Kaisha in 1935. She was chartered to Mitsui and plied the New York route until she was requisitioned on 9 September 1941 by the Imperial Japanese Navy during World War II and converted at the Harima shipyard to a minelayer, which was completed on 31 October 1941.

Assigned to the Mine Division 19, of the Fourth Fleet, she landed troops at Makin Island. As part of the Rabaul invasion fleet, she carried air base construction materials.


On 10 March 1942, during the invasion of Lae-Salamaua, Tenyo Maru suffers two direct bomb hits from SBD's from the United States Navy aircraft carriers USS Lexington and USS Yorktown and breaks in two and sinks off Lae, New Guinea. Tenyo Maru was removed from the Navy List on 1 April 1942.

The bow of the ship was still visible above the water, at the end of the former Lae Airport in the 1970s.
