Ike no Yu
Ike no Yu onsen is a mixed natural hot spring facing Lake Kussharo. The hot spring looks like a big pond and gives you a sense of openness and superb restoration as if you have become one with nature. On fine days, you can enjoy the water surface sparkling golden. The water temperature is quite tepid at 38°C, so summer is the best time for a soak. There are separate changing rooms for men and women.
