Lat N 24°16'  Long E 154°00'  Marcus Island is a small island located in the northwest Pacific Ocean, the most easterly island of Japan. Located 1,148 miles east of Tokyo. The nearest land is East Island in the Maug Islands in the Mariana Islands. In Japanese, known as "Minamitorishima", "Minami Tori Shima" or "Minami-Tori-shima" meaning Southern Bird Island.

On July 19, 1898 Marcus Island was initially claimed by Japan. In 1935, the Japanese Navy established a meteorological station on the island, and built the airfield. A channel was cut through the reef on the northwest side of the island.

Wartime History
At the start of the Pacific War the garrison included the 742 man Minamitorishima Guard Unit, under the command of Rear-Admiral Masata Matsubara and the 2,005 man 12th Independent Mixed Regiment, under the command of Colonel Yoshiichi Sakata.

At the height of the war, over 4,000 Japanese soldiers were stationed on the island. Defended by trench system and beach defenses around the perimeter of the island plus light and heavy anti-aircraft batteries.

Between March 1942 until July 1945 Marcus Island was attacked by American carrier aircraft and bombers and was bypassed, leaving the garrison isolated and cut off from resupply, aside from submarine or rescue.

At the end of the war, the surviving garrison officially surrendered on August 31, 1945 to US Army General Whiting.

In 1951, the Treaty of San Francisco placed the island under American jurisdiction. In 1964 the U. S. Coast Guard opened a LORAN-C navigation station on Marcus, whose mast was until 1985 one of the tallest structures in the Pacific area. In the 1980s the Loran station was maintained by twenty-three US Coast Guard personnel.

In 1968, Marcus was returned to Japan. Today. the island is administratively considered part of Ogasawara, Tokyo.
