大東群島
The Japanese archipelago (Japanese: 日本列島, "Nihon rettō") is a group of 6,852 islands that form the country of Japan. It extends over 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 four island arcs from north to south: the Sakhalin Island Arc, 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.
