A sodium-chloride strong saline hot spring that wells up from underground. With a high salt concentration, the bathwater has a salty film-like feel, warming the body from the core with excellent heat retention.

Sauna & Cold Bath Information
Hot Air Sauna
A three-tiered tower sauna with wide steps on each tier, allowing you to sit comfortably with your legs stretched out. The sauna stones use ceramic artificial stones called "KERKES," and automatic löyly operates every 30 minutes, spreading heat waves throughout the room with ventilation. The men's bath features an "IKI" stove with a large capacity for sauna stones, while the women's bath has a high-performance "ZIEL" stove. The room is illuminated with colored lights, creating a space where you can relax and sweat despite the high temperature. The humidity is high, enveloping the entire body in heat and steam.
Finnish Sauna
A convection-type löyly sauna where water is poured over Mount Fuji lava stones heated to high temperatures. Automatic löyly is performed every 20 minutes, and the far-infrared effect and steam from the lava stones spread throughout the room. The humidity is high, allowing you to warm up thoroughly from the core with a quality of heat that is gentle. It is a three-tiered sauna that can accommodate about 20 people, equipped with a TV, allowing you to enjoy the sauna leisurely. It has a milder temperature range than the hot air sauna, making it suitable for long sweating sessions.
Natural Cold Water Bath
A cold water bath using natural water drawn from underground, characterized by its smooth texture. It lacks the chlorine smell of tap water, with a soft water quality that tightens pores and prevents heat from escaping. It is ideal for cooling down after heating up in the sauna, offering a refreshing cool-down. The pleasantness unique to natural water makes you want to enter repeatedly due to its excellent water quality. Outdoors, there is a covered relaxation space with sun loungers where you can thoroughly enjoy an outdoor air bath.
