Iō Tō (Iwo Jima, Iōjima) Lighthouse Lighthouse

This active lighthouse on Iō Tō, also known historically as Iwo Jima, is a 20-meter cylindrical structure attached to a two-story administration building. Its focal height is 112 meters, providing a geographic range of 26.1 nautical miles. The lighthouse's operational status ensures guidance for vessels in the Pacific Ocean, near the nearest port of Ogasawara, which is 146.7 kilometers away. The site is open to the public, though access to the tower itself is restricted. Its presence contributes to maritime traffic management in this strategically important area.

Why it matters: The lighthouse guides vessels around the historically significant island of Iō Tō, functioning partly as an airport control tower and offering visitors a connection to the island's past and its maritime safety role.
