About Naha City Lighthouses Lighthouse

This concrete post structure, standing 10 meters tall, was erected in 2009 and is situated at the extremity of Naha's detached south breakwater. It features a red tower with a yellow checkerboard pattern and is attached to a single-story equipment building. The light emits a single red flash every 4 seconds, visible for 12.4 nautical miles from a focal height of 17 meters. The site is accessible, but the tower itself is closed to visitors. It is located 1.2 kilometers from the port of Naha.

Why it matters: This lighthouse marks the end of the detached south breakwater, guiding vessels safely into Naha's traditional harbor and preventing them from striking the structure.
