History

During the Edo period, Hachijōjima was known as a place of exile for convicts. This practice ended in the Meiji period, and the island residents developed an economy based on fishing, sericulture, and agriculture. Hachijō Subprefecture was organized on April 1, 1908, and included the villages of Mitsune, Nakanogo, Kashitate, Sueyoshi and Ōkago. The villages of Toruchi and Utsuki on Hachijōkojima were organized on May 3, 1947. The five villages of Hachijōjima merged on October 1, 1954, to form the village of Hachijō. On April 1, 1955, the two villages of Hachijōkojima also merged with the village of Hachijō, which was promoted to town status. However, in March 1966, the residents of Hachijōkojima voted to abandon their island, citing the inaccessibility of basic public services and economic difficulties, and Hachijōkojima became a deserted island from June 1969.

Economy

Fishing and tourism are the mainstays of the economy of Hachijō.
