Aone Onsen Mixed Source (Shinmyogo, Hanabusa, Shin-yu, Yama-no-yu, Zao-no-yu and Oyu)
Analysis UnverifiedAone Onsen is said to have opened in 1528 and served as the palace bath of the Date clan of the Sendai domain. This 49.8°C blend of six sources flows into the tubs without added water or heating: a clear, light simple spring. With moderate sulfate and bicarbonate, it leaves the skin feeling fresh and light. Gentle and slowly warming, it suits those who wish to sink quietly into historic stone and wooden tubs in the snowy mountains of Zao.
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.
This gentle simple spring can run around 43°C near the spout. Pour water over yourself first, start with about five minutes, rest between soaks, and drink water after bathing.
With 824.5 mg/kg of dissolved solids, this mild simple spring is easy on the body. Its 223.4 mg/kg of sulfate brings a lingering warmth, suited to days when a stiff body needs loosening or when you simply want to ease fatigue slowly.
Though gentle, avoid lightheadedness from long soaks; those with heart or blood-pressure concerns should keep baths short.
