Yumoto Onsen Mixed Spring (Register No. Yumoto 12, 72, 84, 89, 99, 112)
Analysis VerifiedThe Yumoto Onsen Mixed Spring (Registers 12, 72, 84, 89, 99, and 112) is a luxurious blend of six distinct sources gushing in the Hakone Yumoto area. Symbolizing the abundant waters of historically renowned Hakone, this spring generously supplies leading local inns, continuously soothing bathers with its stable and comforting mineral qualities.
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.
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.
As the water is used at a high temperature of 60.0°C, please pour water over yourself to adjust before entering. Do not rinse off afterward; simply towel dry to retain the salt's warming veil on your skin.
Rich in sodium (750mg/kg) and chloride (1570mg/kg), this spring forms a delicate veil of salt over the skin, preventing heat loss. The 63.0°C thermal energy and gently alkaline pH of 8.1 will thoroughly warm those suffering from poor circulation and xeroderma from the core.
Avoid bathing if you have an active fever, tuberculosis, advanced malignancies, or severe heart, lung, or kidney conditions. Elderly guests should avoid extended full-body immersion in high temperatures.
