Nozawa Kama Mixed Spring (Marugama, Yudegama, Takenoshigama, Shimogama, Ontake no Yu)
Analysis UnverifiedDrawn from Ogama, the boiling pools where villagers still cook vegetables and eggs, this clear water carries a strong sulfur scent and flakes of white mineral bloom. Sulfate-rich and alkaline, it warms deeply and feels smooth on the skin: a hard-working spring that has served village life for centuries.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A natural moisturizer also used in skincare lotions. Forms a thin veil on the skin to reduce moisture loss after bathing.
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.
The source runs at 77.0°C, so test the water and keep clear of the inlet. The sulfur smell is strong: bathe with good ventilation, remove silver jewelry, and moisturize after soaking in this pH 8.96 water.
With 529.0 mg/kg sulfate, the water warms the body steadily and suits relieving pain in stiff muscles and joints, while 5.2 mg/kg hydrosulfide sulfur boosts circulation for restorative warmth.
The 77.0°C source can scald near inlets. Ventilate well because of the hydrogen sulfide, avoid long soaks, skip bathing when unwell or after alcohol, and stay hydrated.
