About Sagiura Lighthouse

Located on a promontory west of Sagiura Bay's entrance in Japan's Shimane Prefecture, the Sagiura lighthouse is a white, cylindrical concrete tower built in 2015. It stands 8 meters tall with a focal height of 57 meters, emitting a white flash every 4 seconds. This structure replaced an earlier lighthouse first established in 1959. The site is open to the public, though the tower itself is closed. The nearest port is Kawashimo, 3.7 kilometers away.

Why it matters: The Sagiura lighthouse is significant for guiding vessels entering and exiting Sagiura Bay, preventing groundings on the promontory.
