Minamitori-shima

sometimes Minami-Tori-shima or Minami-Torishima, also known as Marcus Island, is an isolated Japanese coral atoll in the northwestern Pacific Ocean, located some southeast of Tokyo and east of the closest Japanese island, South Iwo Jima of the Volcano Islands, and nearly on a straight line between mainland Tokyo and Wake Island, further to the east-southeast. The closest island to Minamitorishima is East Island in the Mariana Islands, which is 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 (), it is of strategic importance, as it enables Japan to claim a exclusive economic zone in the surrounding waters. It is also the easternmost territory of Tokyo, being administratively part of Ogasawara Subprefecture. No civilians live there, except personnel of the Japan Meteorological Agency, Japan Self-Defense Forces (JSDF), and Japan Coast Guard serving temporary tours of duty on the island. The island is off limits to civilians except for Japan Meteorological Agency staff, although reporters, documentary makers, and scientific researchers can sometimes get an entry permit. No commercial boat tours or flights visit the island, and civilians are currently not allowed access to Minamitorishima for tours or sightseeing, due to its use by the JSDF as an observation station. Because of its isolation, it is of some interest to amateur radio hobbyists, since the island is counted as a separate country for amateur radio awards based on station contacts. Minamitorishima is very isolated. There is no other land for over in any direction. The island is triangular in shape, and has a saucer-like profile, with a raised outer rim of between above sea level. The central area of the island is below sea level. Minamitorishima is surrounded by fringing reefs, which range from in width, enclosing a shallow lagoon, which is connected with the open ocean by narrow passages on the southern and northeastern sides.
