Kurami No. 3
Analysis UnverifiedKurami No. 3 is a spring of Kurami Onsen, tucked into the hills of northern Kakegawa, where some 10.7 liters per minute well up naturally. Kurami No. 3 emerges nearly colorless with a faint whiff of hydrogen sulfide, and its pH 9.5 alkalinity gives the water a silky, slippery touch that lingers on the skin after bathing. It suits anyone hoping to unwind quietly in a mountain village while caring for their skin.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
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 pH 9.5 alkalinity that lifts away oils and old skin cells, go easy on soap and soak for about ten minutes at a time. Moisturize afterward so the silky smoothness lasts longer, and take off silver jewelry first.
At pH 9.5, with 33.7 mg/kg of carbonate ions, the water softens dull skin and may support the silky skin feel bathers prize. Sulfur springs like this one, carrying 7.2 mg/kg of hydrosulfide, are traditionally associated with balneotherapy, and suit days spent quietly caring for yourself and your skin.
Sulfur can tarnish metal jewelry, and alkaline water may dry sensitive skin, so remove accessories before bathing and moisturize well afterward.
