About Shiroshima Saki Lighthouse
Also known as: Shiroshima Saki (Oki Syoto)
The Shiroshima Saki lighthouse, a cylindrical concrete tower standing 16 meters tall, was first lit in 1956. Its lantern and gallery sit atop a keeper's house, also made of concrete. The lighthouse is situated on a summit at the northern tip of Dōgo island, providing a focal height of 258 meters. This elevated position allows its white light to have a geographic range of 37.7 nautical miles. A renovation in 1981 converted the keeper's house into a radio direction finding station. The site is open to the public, though the tower remains closed.
Why it matters: Distinguished as one of the highest lighthouses in Asia, Shiroshima Saki's powerful white flash every 15 seconds offers significant guidance for vessels navigating the waters around Dōgo island.
