The Volcano Islands or Ioretto (火山列島 Kazan Rettō?) is a group of three Japanese islands south of the Bonin Islands that belong to the municipality of Ogasawara. 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 (12.57 sq mi) and a population of 380.
The Volcano Islands are:
- Kita Iwo Jima (北硫黄島 Kita-Iō-jima or Kita-Iō-tō, literally North Sulphur Island), 5.57 square kilometres (2.15 sq mi), 792 metres (2,598 ft) (Sakaki-ga-mine)
- Iwo Jima (硫黄島 Iō-jima or Iō-tō, literally Sulphur Island) 20.60 square kilometres (7.95 sq mi), 166 metres (545 ft) (Suribachi-yama)
- Minami Iwo Jima (南硫黄島 Minami-Iō-jima or Minami-Iō-tō, literally South Sulphur Island) 3.54 square kilometres (1.37 sq mi), 916 metres (3,005 ft)

The first recorded sighting by Europeans was in October 1543 by Spanish navigator Bernardo de la Torre on board of carrack San Juan de Letrán when trying to return from Sarangani to New Spain. Iwo Jima was charted as Sufre, the old Spanish term for sulphur.
The population was about 1,100 in 1939, distributed among five settlements: Higashi, Minami, Nishi, Kita and Motoyama (meaning "East", "South", "West", "North" and "Mountain of Origin", or central mountain) on Iwo Jima; and two settlements on Kita Iwo Jima: Ishino-mura ("Ishino village"; Ishino is a surname) and Nishi-mura ("West village"). The municipal administration office was located in Higashi until 1940, when the municipality was integrated into the administration of Ogasawara, Tokyo.
