Hot Spring & Bath Information

Ryusenji Onsen

TypeNatural Hot Spring

When you immerse yourself in the water gushing from 2,000 meters underground, the blackish, smooth texture gently envelops your entire body, and your breathing becomes slow and deep. The water temperature powerfully warms your core, and even after getting out, the warmth continues as if a fire is lit inside. The chloride-rich water supports heat retention and moisturization, helping to alleviate coldness and stiffness, recover from fatigue, and reset stress-related discomforts, leaving your skin calm and moist after bathing. If you soak in the open-air rock bath or waist bath while feeling the breeze, your mind and body will quietly relax, making you feel at ease even in the city.

Men's

An entertainment-style sauna where an automatic löyly is activated every hour on the hour and at 30 minutes past, causing heat and steam to rush into the room. Although the set temperature is around 90°C, the perceived temperature during löyly activation is even higher. The upper seats have such an impact that expressions like 'feels like getting burned' are used, and after experiencing the intense heat wave, you can aim for the pinnacle of 'totonou' through alternating with cold water baths.

Men's

An ultra-low temperature single cold plunge bath that instantly drags your body, heated thoroughly in the sauna, into silence. The water temperature is set in the single-digit range, and when you submerge up to your shoulders, a cold stimulus that feels like it pierces your skin rushes through, cooling you down to your core.

With a milder temperature range compared to the single, it plays the role of gradually calming your body temperature. By using it before and after the intense single cold plunge bath, it softens the shock to your body, allowing you to enjoy the sauna more comfortably for a longer period.
