Atolls of Japan

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.
