Kodomari Kō North Breakwater Lighthouse

A red concrete post, 9 meters in height, marks the north breakwater at Kodomari. This post is centered on a square, one-story concrete equipment shelter. The light first became operational in 1935, providing a red flash every 3 seconds. Its focal height reaches 13 meters above sea level, offering a geographic range of 11.3 nautical miles. The structure was relocated in 2015 to accommodate an extension of the breakwater. The site is open to the public, though the tower itself is closed.

Why it matters: This light clearly delineates the extensive north breakwater for vessels entering and exiting Kodomari harbor. Its relocation in 2015 demonstrates its ongoing adaptation to port development.
