"Maebashi Onsen Kua-i Therme" is a rare medical-partnership hot spring facility in Japan, attached to an orthopedic clinic. The spring water, gushing from 1,500m underground, is a rich sodium-chloride hot spring with a strong oily aroma and salty taste, and it flows fresh into the baths without any dilution. The sauna is a full-fledged dry sauna with four tiers of tower-style seating, offering powerful heat on the top level and a gentler, more gradual warming on the lower levels. The cold plunge bath is set at a comfortable temperature, making it ideal for alternating between hot spring bathing and cold immersion. There are also extensive health-focused facilities such as walking baths and jacuzzis, making this a famed hot spring loved by those seeking deep healing like a therapeutic stay.
