About Sugashima Kō South Breakwater Lighthouse

This 8.5-meter white concrete post, topped with a focal height of 12 meters, stands on a round, one-story equipment room. It is situated on a breakwater marking the southern entrance to Suga Shima's harbor in Toba, Mie Prefecture, Japan. The light emits a green signal, characterized by an occulting green flash every 6 seconds, visible for 11 nautical miles. The site is accessible, though the tower itself is closed to visitors. This structure serves as a navigational aid for vessels entering and exiting the local port.

Why it matters: The light's placement directly on the breakwater clearly defines the harbor entrance, aiding local shipping and fishing fleets in safe navigation.
