About Yu Shima Lighthouse
Yu Shima Lighthouse stands on the westernmost point of a small, roughly one-kilometer-diameter island in Ariake Bay. Established and first lit in 1916, the lighthouse features a white, round cylindrical concrete tower topped with a lantern and gallery. It rises 11.5 meters, with its light positioned 39 meters above sea level. The characteristic is a single white flash every 3 seconds, visible for nearly 17 nautical miles. The site is accessible to the public, though the tower itself remains closed.
Why it matters: This lighthouse is important for guiding vessels, including passenger ferries, through Ariake Bay, marking the western edge of the island.
