A full-fledged Finnish-style self-löyly sauna that was renovated for both men and women in January 2024. The seating and walls are all wrapped in the warmth of wood, and guests can enjoy luxurious self-löyly using rosemary water from Higashikawa. As the steam rises throughout the room, humidity is kept high, allowing even those who do not like saunas that are too hot to breathe comfortably while enjoying a generous sweat from deep within the body.

A new-style cold plunge bath inspired by the famous Ginga Falls and Ryusei Falls of Sounkyo Onsen, featuring a waterfall installation that pours down from a height of about 2 meters. By receiving cool water from above, you can rapidly cool down your heated body after the sauna and feel instantly refreshed. The open-air bath area is equipped with deck chairs for outdoor air bathing, letting you relax in a prime seat with sweeping views of the majestic Daisetsuzan mountains.
