The Ogasawara Islands (小笠原諸島) are an archipelago of over 30 subtropical islands some 1000 km directly south of central Tokyo, Japan. Administratively, they are a part of Tokyo. The islands are also known as the Bonin Islands, and the southernmost (uninhabited) group is known as the Volcano Islands.
The only inhabited islands are Chichi-jima (父島, lit. "Father Island") and Haha-jima (母島, "Mother Island"). Access to these islands is possible only via a single weekly overnight ferry from Tokyo, although there are plans to open an airport. Tourists are attracted to the islands by scuba diving and whale watching.
The uninhabited Iō-jima (硫黄島, "Sulphur Island"), better known in English as Iwo Jima, is a part of the Volcano Islands. Access to the island requires special permission.

The volcano can be extremely violent, and destroyed several towns in the 1950s, yet the area at its foot is densely populated, with vineyards, orchards, and orange groves.

Most volcanoes occur on plate margins (see plate tectonics), where the movements of plates generate magma or allow it to rise from the mantle beneath.
