About To Shima Breakwater Lighthouse
Also known as: Toshima
This red, cylindrical concrete tower stands 7 meters tall and emits a red light with a focal height of 10 meters. Its distinctive warning signal consists of a single red flash every 3 seconds. Located at the seaward end of the To Shima Breakwater, it marks the harbor's entrance. The lighthouse has a geographic range of 10.4 nautical miles. The site is open to the public, though the tower itself is closed.
Why it matters: The lighthouse is essential for the safe navigation of local vessels entering and exiting the harbor. Its red flash warns mariners of the breakwater's end, preventing groundings or collisions in this busy coastal area.
