About Nakira Kō Lighthouse

Also known as: Nakira Kō (Inner Breakwater)

Built in 1928, the Nakira Kō lighthouse is a cylindrical concrete tower standing 9 meters tall, painted white. It is situated on a short pier at Nakira, a harbor sheltered by Daio Saki. The light emits a single green flash every 3 seconds, visible for 11.3 nautical miles. Originally serving as a guide into the harbor, its navigational significance has diminished following extensions to the port's breakwaters. Although the tower is closed to the public, the site remains accessible, offering a view of this historic structure.

Why it matters: The lighthouse is recognized as a historical landmark for the Nakira community, representing a connection to the harbor's past maritime activities.
