Sano Gyoko Lighthouse
Location & Light Range
About Sano Gyoko Lighthouse
Established in 1961, this cylindrical concrete lighthouse stands 8.5 meters tall on the north breakwater of Izumisano's yacht harbor. Its focal height reaches 13 meters, casting a green flash every 4 seconds. The structure is a round concrete tower, flaring slightly at the top, connected to a small equipment shelter. It marks the end of the breakwater, offering a geographic range of 11.3 nautical miles. The site is accessible to visitors, though the tower itself remains closed.
Why it matters: This lighthouse is essential for safe navigation into the Sano yacht harbor, marking the north breakwater's end to prevent groundings and collisions, particularly for recreational yachts and fishing boats.
