The Japanese archipelago (Japanese: 日本列島, Nihon Rettō) is an archipelagoof14,125 islands that form the country of Japan.[1] It extends over 3,000 km (1,900 mi)[2] from the Sea of Okhotsk in the northeast to the East China and Philippine seas in the southwest along the Pacific coast of the Eurasian continent, and consists of three island arcs from north to south: the Northeastern Japan Arc, the Southwestern Japan Arc, and the Ryukyu Island Arc. The Daitō Islands, the Izu–Bonin–Mariana Arc, the Kuril Islands, and the Nanpō Islands neighbor the archipelago.
Japan is the largest island countryinEast Asia and the fourth-largest island country in the world with 377,975.24 km2 (145,937.06 sq mi).[3][4] It has an exclusive economic zone of 4,470,000 km2 (1,730,000 sq mi).[5]
The term "mainland Japan" is used to distinguish the large islands of the Japanese archipelago from the remote, smaller islands; it refers to the main islands of Hokkaido, Honshu, Kyushu and Shikoku.[6] From 1943 until the end of the Pacific War, Karafuto Prefecture (south Sakhalin) was designated part of the mainland. Geographically speaking the term "mainland" is somewhat inaccurate, as this refers to an expanse of territory that is attached to a continental landmass.
The term "home islands" was used at the end of World War II to define the area where Japanese sovereignty and constitutional rule of its emperor would be restricted.[citation needed] The term is also commonly used today to distinguish the archipelago from Japan's colonies and other territories.[7]
