The Izu Islands, formerly the De Vries Archipelago, are a group of volcanic islands stretching south and east from the Izu Peninsula of Honshū, Japan. Administratively, they form two towns and six villages; all part of Tokyo Prefecture. The largest is Izu Ōshima, usually called simply Ōshima.
Although usually called the "Seven Islands of Izu", there are in fact more than a dozen islands and islets. Nine among them are currently inhabited.
