Hinazakura
Analysis UnverifiedThe Hinazakura source is one of several springs pumped from the national forest at the far end of Nyuto Onsen, an area named for the crabs that live in its mountain streams. Here each bathhouse draws on its own source, so the waters share a type yet differ subtly in their minerals. Rare among Nyuto's milky springs, this one runs clear, with a slight silkiness, drifting white mineral flakes and a gentle sulfur scent that soothe the skin, a spring for anyone who wants to linger quietly above the beech forest.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
The aroma typical of sulfur springs, with circulatory and antibacterial effects.
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.
Mildly alkaline at pH 8.3, the water feels soft and suits a slow, unhurried soak. Remove silver jewelry because of the sulfur, and moisturize afterward to keep the smooth feel on the skin.
A simple sulfur spring with 3.0 mg/kg of hydrosulfide ion, it is traditionally associated with immune system stimulation, while its mildly alkaline pH 8.3 may support silky skin by softening the outer layer of the skin.
Check the temperature before entering since the source is hot, and avoid long soaks or poorly ventilated spaces because of the hydrogen sulfide.
