The Volcano Islands are a group of three Japanese-governed islands in Micronesia. They lie south of the Ogasawara Islands. The islands are all active volcanoes lying atop an island arc that stretches south to the Marianas. They have an area of 32.55 square kilometres, and a population of 380.
The Volcano Islands have a subtropical climate. They are part of the Ogasawara subtropical moist forests ecoregion and are home to unique and diverse plants and animals, including many endemic species. They have been recognised as forming an Important Bird Area by BirdLife International because they support populations of red-tailed tropicbirds, Japanese wood pigeons and Matsudaira's storm petrels.
