Ogasawara Subprefecture (小笠原支庁, Ogasawara-shichō) is a subprefecture of Tokyo Metropolis, Japan. The subprefecture covers the Bonin Islands and includes the village of Ogasawara; and the prefectural government maintains a main office on Chichijima and a branch office on Hahajima.

The subprefecture covers 104.41 square km and 2,415 people.
The Ogasawara Islands refer to a scattered group of islands in the Northwest Pacific south of the Japanese main island of Honshū. They consist of the Ogasawara archipelago, the Volcano (Io or Iwo) Islands and several isolated islands.
History
Until 1830, the Ogasawara Islands were uninhabited and thus called "Muninjima" (meaning "uninhabited island"). This Japanese name was transliterated or transformed into the more widely known English name—the Bonin Islands.
These Bonin Islands (the Ogasawara archipelago) are composed of the three island groups:
These main island clusters are encompassed within the Tokyo prefectural administrative area known as the Ogasawara Subprefecture; but only the islands of the Ogasawara archipelago are traditionally considered to be the Bonin Islands. These geologically older and larger islands are traditionally considered distinct from the administratively-related but geologically newer and smaller island clusters and other isolated outcroppings in this part of the Pacific.
Okinotorishima was added to the subprefecture in 1930.
The current Japanese administrative structure has its historical organizational roots in the post-war occupation of these strategically positioned Pacific islands. In the 23 years that UN Trust Territory was administered by the Americans, the region was known as the Bonin-Volcano Islands. Prior to repatriation in 1968, this military strategic area remained under the control of U.S. military occupation forces.
Geography
The three main groups which comprise the Bonin Islands are at the northern end of the archipelago. All the islands together comprise only 61 square kilometers; and they are:
Development
Lessons learned the hard way from the experience of the Galapagos Islands are potentially paradoxical. The ecosystem fragility is well documented; and it suggests comparisons with the cautious development history of the Galapagos.
The islanders also stress the uniquely multicultural roots of the Ogasawara life, where roughly one-tenth of the Japanese population is descended from early European and American settlers, with some families going back up to seven generations.
