Mugi Kō West Breakwater Lighthouse

Iso White 6s🇯🇵Mugi, JPOperational

This 9.5-meter round concrete lighthouse, first lit in 1981, stands at the end of Mugi's west breakwater. The structure is a white concrete post topped with a lantern, connected to a one-story equipment shelter, with the entire lighthouse painted white. It emits an isophase white light on a 6-second cycle, visible for 11.6 nautical miles. The lighthouse guides vessels into Mugi Port, helping them avoid the breakwater's submerged sections, especially during periods of reduced visibility. The site is accessible to the public, though the tower itself is closed.

Why it matters: This lighthouse is essential for guiding local fishing fleets and other vessels safely into Mugi Port, clearly delineating the end of the west breakwater. Its continuous white light helps prevent groundings and collisions within the busy harbor approach.
