Beyond its striking presence, the soothing sound of the clear stream offers a sense of tranquility. If you wish to fully immerse yourself in the vast beauty of nature while enjoying an Onsen, this is undoubtedly a highly recommended choice.
This was my first visit.Above all, the open-air bath with its wonderful sense of openness surrounded by beautiful nature, and the atmosphere throughout the property, were truly lovely. I would definitely like to return in a different season.I was very satisfied.
今日も晴天 6/14/2026This was my fourth stay. When the bus I planned to take was delayed, you kindly accommodated changes to the Shuttle Service, for which I am truly grateful. As always, staying at the snow-covered Onsen warmed both my body and soul.
