About Oki Kō Breakwater Lighthouse
This cylindrical concrete tower, standing 9.5 meters tall with a focal height of 11 meters, is painted white and marks the western breakwater at Oki Kō, the port of Haha Jima.

The site is open to the public, though the tower itself is closed. It serves as a navigational aid at the harbor entrance.
