Location & Light Range
About Takamatsu Detached Breakwater Southwest Head Lighthouse
This operational lighthouse is situated at the southwest end of Takamatsu's detached breakwater. The structure is an 11-meter tall, cylindrical concrete tower with a flared top and an attached equipment shelter. Its focal height is 13 meters, and it emits an isophase green light on a 6-second cycle, visible for 11.3 nautical miles. The lighthouse is located in Kagawa Prefecture, about 0.3 kilometers from the nearest port, Takamatsu. Access is restricted to boat only, and the site and tower are closed to the public.
Why it matters: This lighthouse warns mariners of the end of the detached breakwater, preventing collisions and safeguarding passage into Takamatsu Port, a busy area within the Seto Inland Sea.
