Minamitorishima (南鳥島, lit. 'Southern Bird Island'), also known as Marcus Island, is an isolated Japanese coral atoll in the northwestern Pacific Ocean, located some 1,848 kilometers (1,148 mi) southeast of Tokyo and 1,267 km (787 mi) east of the closest Japanese island, South Iwo Jima of the Ogasawara Islands, and nearly on a straight line between mainland Tokyo and Wake Island, 1,415 km (879 mi) further to the east-southeast. The closest island to Minamitorishima is East Island in the Mariana Islands, which is 1,015 km (631 mi) to the west-southwest. It is the easternmost territory belonging to Japan, and the only Japanese territory on the Pacific Plate, past the Japan Trench. Although small (1.51 km2 (1 sq mi)) it is of strategic importance, as it enables Japan to claim a 428,875 square kilometers (165,589.6 sq mi) exclusive economic zone in the surrounding waters. It is also the easternmost territory of Tokyo, being administratively part of Ogasawara village. There is no civilian population, except personnel of the Japan Meteorological Agency, JSDF, and Japan Coast Guard serving temporary tours of duty on the island. (Source: Wikipedia.org, CC BY-SA)
