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.
