About Mitarai Ōshima Lighthouse
This concrete lighthouse, built and first lit in 1975, stands 9 meters tall. Its round white tower has a focal height of 11 meters and emits a single white flash every 3 seconds. The structure includes a square, single-story equipment shelter. Mitarai Ōshima lighthouse is situated on the northern point of an island, located off the northeast point of Osaki Shimo-jima. It marks the entrance to a narrow passage and has a geographic range of 10.7 nautical miles. The site is open to the public, but the tower itself is closed.
Why it matters: This lighthouse is essential for safe navigation through the narrow passage it marks, a critical route for local maritime traffic around Osaki Shimo-jima. Its consistent white flash provides a reliable reference point, preventing groundings and collisions in a complex island environment.
