About Sumoto Kō Lighthouse
Sumoto Kō Lighthouse is a 9-meter white concrete post erected in 1982. It is attached to a 1-story concrete equipment shelter and stands at the end of Sumoto Harbor's west breakwater. The lighthouse emits a single green flash every 4 seconds, visible for nearly 11 nautical miles. Its focal height is 11 meters above the water. This structure serves as a navigational aid within Amakusa city.
Why it matters: The green light clearly marks the termination of the west breakwater, guiding maritime traffic safely into and out of Sumoto Harbor. Its presence helps prevent groundings within the busy port entrance.
