Gani-yu Hot Spring, a symbol of Nagayu Onsen town, is steeped in the legend of a crab who fell in love with a human daughter. This free, mixed-gender open-air bath along the river offers a liberating natural experience. Changing rooms are located under the bridge, and swimsuits are allowed for women. While open 24 hours, visitors should bring their own towels and amenities. Be aware that the bath's temperature can be cool, especially in winter. It's a unique spot for a quick dip or foot bath while exploring Nagayu Onsen.
