Kuraoki, Kajika and Senju Mixed Source
Analysis UnverifiedTanigawa Onsen rises along a clear mountain stream at the foot of Mount Tanigawa and has long been called "Mimosuso no Yu", after a legend that the goddess Konohanasakuya-hime turned the river into hot water by washing the hem of her robe. This water is a blend of three pumped sources of differing temperatures. Clear and colourless, balanced between sulfate and chloride, it wraps the body softly and suits those who wish to soak quietly while gazing at snowy or verdant river views.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A trace component with gentle antibacterial and anti-inflammatory action.
Scores are calculated from mineral analysis data based on the Mineral Spring Analysis Guidelines (Ministry of Environment, Japan). They are unrelated to facility atmosphere or service quality.
▸Note
The temperature, pH and component values shown here are based on the hot spring analysis (source). Actual values in the bath may differ depending on heating, dilution, recycling and filtration. Please check current usage status at the facility.
With a source temperature of 41.4°C, close to body heat, the water suits slow 15–20 minute soaks. Its chloride content keeps warmth lingering afterward, so towel off promptly and rehydrate.
Rich in 682 mg/kg of sulfate and 259 mg/kg of calcium, sulfate springs have long been valued for balneotherapy. Chloride forms a light film on the skin, offering restorative warmth that lingers long after you leave the bath on snowy Tanigawa nights.
This mildly alkaline water is gentle, but its chloride keeps the body warm after bathing, so avoid overly long soaks and stay hydrated. The water may be heated in winter.
