Lake Toya Onsen
A gentle and abundant natural hot spring that allows you to take in a panoramic view of the scenic Lake Toya right before your eyes. The spring quality is sodium-calcium bicarbonate, sulfate, and chloride hot spring, and while it has a smooth texture, it leaves your skin astonishingly moist after bathing, making it a true beauty bath. At Hoshi no Yu on the top floor, you can enjoy a special bathing experience that combines spectacular views and a famous hot spring, including an infinity open-air bath that seems to blend into the lake surface, and at Tsuki no Yu, a garden-style bath featuring a giant famous stone.
