Nanpō Islands
The Nanpō Islands is a collective term for the groups of islands that are located to the south of the Japanese Archipelago. They extend from the Izu Peninsula west of Tokyo Bay southward for about, to within of the Mariana Islands. The Nanpō Islands are all administered by Tokyo Metropolis.
The Hydrographic and Oceanographic Department of the Japan Coast Guard defines the Nanpō Shotō as follows:Nanpō Shotō
- * Izu Shotō
- * Ogasawara Guntō
- ** Mukojima Rettō
- ** Chichijima Rettō
- ** Hahajima Rettō
- * Kazan Rettō
- ** Kita Iwo Jima
- ** Iwo Jima
- ** Minami Iwo Jima
- ** Nishinoshima
- * Okinotorishima
- * Minamitorishima
Archeological evidence has since revealed that some of the islands were prehistorically inhabited by members of an unknown Micronesian ethnicity. The Japanese claim to have discovered the islands in 1593; however, many of the islands were known by the Spanish sailors that went from Philippines to New Spain since Bernardo de la Torre's voyage in 1543, while the British claimed the islands in 1827. However, neither Japan nor Britain developed the Nanpō Islands, although a small colony of Bonin Islanders was established at Chichi-jima.
Some Japanese began migrating to the islands in 1853, and the Shogunate government attempted to claim the islands in 1861. In 1876, the Meji government of Japan formally incorporated Ogasawara islands into the territory with the consent of the Western powers, placing them under the administration of the Tokyo Prefecture. And in 1891 Japan incorporated the more southerly and then-uninhabited Volcano Islands as part of Ogasawara Subprefecture.
By the mid-1930s the islands were closed to foreigners and a small Imperial Japanese Navy base was established at Chichi-jima. As the war intensified and U.S. forces approached in 1944, most of the civilians living on the islands were forced to evacuate.
After World War II, the islands were administered by the United States under Article III of the Treaty of San Francisco until they were returned to Japan in 1968. In 2011, the Ogasawara Islands were included on UNESCO’s World Heritage list.
