About Owari Ō Iso Lighthouse
Owari Ō Iso is a cylindrical concrete tower standing 9 meters tall, painted yellow with a single black horizontal band. It is situated on a reef at the entrance to Atsumi Bay, marking the passage between Saku Shima and Himaka Shima. The light emits a white flash every 15 seconds from a focal height of 10 meters, with a geographic range of 10.4 nautical miles. The site is open to visitors, but the tower itself is closed to the public. The nearest port is Shinojima, approximately 2 kilometers away.
Why it matters: This lighthouse is essential for safe navigation through the narrow passage between Saku Shima and Himaka Shima, directly at the entrance to Atsumi Bay, warning mariners of the reef it marks.
