Kidachi Onsen Yugashima No. 23
Analysis UnverifiedKidachi Onsen Yugashima No. 23 takes its name from a legend that Minamoto no Yoritomo, spotting steam among the rocks while hunting, pried them up with a wooden sword and released the water. Set beside the Kano River in literary Amagi-Yugashima, its calcium and sodium share the cations almost equally while sulfate and bicarbonate balance the anions. Clear, tasteless and odorless, it is a quiet, unassuming water.
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.
This mild simple spring suits long, unhurried soaks at a gentle temperature. The source is only 32.5°C, so check the heated bath first, then rehydrate and dress promptly afterward.
At pH 8.17 with just 0.189 g/kg of minerals, this gentle simple spring is easy on skin and body, ideal for deep relaxation to the sound of the river, and may support quiet rejuvenation after a day of travel.
Though mild, avoid overly long soaks and dehydration; people with contraindications such as active tuberculosis, serious heart disease or severe anemia should refrain.
