About Izu Misaki Lighthouse

Built in 1909, the Izu Misaki Lighthouse is a 10-meter cylindrical stone tower. Its light flashes white once every five seconds, visible for 14.1 nautical miles. The structure was originally painted white, but in 2023 its lower two-thirds were painted black, creating a distinct appearance. The lighthouse's focal plane is 24 meters above sea level. The site is open to the public, though the tower itself is closed.

Why it matters: The lighthouse's design, using roughly cut stone blocks, represents a rare surviving example from an early period of Japanese lighthouse construction.
