Rausu Kō South (No. 1) Breakwater Lighthouse

Structure: The Rausu Kō South (No. 1) Breakwater light guides mariners into the bustling fishing port of Rausu, nestled on the Shiretoko Peninsula in Hokkaido, Japan. Established in 1964, this light has been a constant presence for local fishing fleets navigating the often-challenging waters of the Nemuro Strait. The port itself is a vibrant hub, particularly known for its rich fishing grounds, including kelp, sea urchins, and various fish species. The light's green flash, appearing every three seconds, offers a clear signal to vessels approaching the harbor entrance, especially crucial during the region's frequent fogs or the long, dark winter nights. While the site around the breakwater is accessible, allowing visitors to observe the working port environment and the light from a distance, the tower itself remains closed to the public, serving its operational purpose without interruption. It continues its vital role in ensuring safe passage for the fishing boats that are the lifeblood of Rausu's economy.
