The Myoko Maru (Kanji:妙高丸) was a 4,103-gross register ton cargo ship built by Mitsubishi Jukogyo Kabushiki Kaisha, Yokohama for Nippon Yusen Kabushiki Kaisha in 1939. She was transferred to Toa Kaiun Kabushiki Kaisha in 1939 and was requisitioned in 1941 by the Imperial Japanese Army during World War II.
On 7 January 1943, Myoko Maru was damaged by United States aircraft of the 49th Fighter Group off Lae, New Guinea, whereupon it was steered up on the beach near Malahang at 06°49'S, 147°04'E, where it was bombed again the next day and destroyed; it became known as the "Malahang wreck". During the war, the ship provided accommodation for thousands of American and Australian troops moving north. After the war the ship was used by John F. Hoile, who turned the hull of the ship into an engineering workshop. By this time the ship was entirely beached.[2]
