The Japanese archipelago (Japanese: 日本列島, Nihon rettō) is a group of 6,852 islands that form the country of Japan as well as the Russian island of Sakhalin. It extends over 3,000 km (1,900 mi) [1] from the Sea of Okhotsk in the northwest to the East China and Philippine Seas in the southwest along the Pacific Ocean coast of the Eurasian continent, and consists of three island arcs from north to south: the Northeastern and Southwestern Japan Arcs, and the Ryukyu Island Arc. The Kuril Island Arc, the Daitō Islands, and the Nanpō Islands are not parts of the archipelago.[ clarification needed ]

Japan is the largest island country in East Asia and the fourth-largest island country in the world with 377,975.24 km2 (145,937.06 sq mi). [2] [3] It has an exclusive economic zone of 4,470,000 km2 (1,730,000 sq mi). [4]

Terminology

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. [5] From 1943 until the end of the Pacific War, Karafuto Prefecture was designated part of the mainland.

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. [6]

Names of Okinawa

Okinawa (沖縄) is a name with multiple referents. The endonym prototypically refers to Okinawa Island in southwestern Japan. Today it can cover some surrounding islands and, more importantly, can refer to Okinawa Prefecture, a much larger administrative division of Japan, although the people from the Miyako and Yaeyama Islands still feel a strong sense of otherness to Okinawa.

Due to changes in sea level, Japan has at various times been connected to the continent by land bridges, with continental Russia to the north via the Sōya Strait, Sakhalin, and the Mamiya Strait, and with the Korean Peninsula to the southwest, via the Tsushima Strait and Korea Strait. Land bridges also connected the Japanese Islands with each other. These land bridges enabled the migration of terrestrial fauna from the continent and their dispersal within Japan.
