About Yanagi Kō Lighthouse
Built in 1976, this lighthouse stands at the end of Yanagi harbor's west breakwater. The structure is an 8.5-meter white concrete post topped with a lantern, attached to a 1-story concrete equipment shelter. Its focal height reaches 12 meters above sea level. The lighthouse emits a green light, flashing every 4 seconds, with a geographic range of 11 nautical miles. The site is open to the public, though the tower itself is closed.
Why it matters: This lighthouse serves as a clear marker for vessels entering Yanagi harbor, guiding them around the west breakwater and preventing groundings in the port environment.
