About Kikuma Kō Lighthouse

This concrete lighthouse was first lit in 1930 and stands at 9.5 meters tall. Its construction consists of a concrete post attached to a single-story square equipment building. The tower, painted red, emits a single red flash every 6 seconds. It is situated at the end of the main breakwater for Kikuma, a fishing harbor located in southwestern Imabari within the Ehime Prefecture. The geographic range of its light is 10.7 nautical miles. While the site is accessible to the public, the tower itself remains closed.

Why it matters: This lighthouse is essential for the local fishing fleet, providing critical navigation guidance for vessels entering and exiting Kikuma harbor. Its specific location at the end of the main breakwater directly prevents groundings and collisions in this busy port.
