Doto Onsen Hotel Yugenen Spring
Analysis UnverifiedStruck in the 1980s from a deep well in downtown Obihiro, this spring carries plant-derived humic matter from beneath the Tokachi Plain. Its pale-brown water clings to the skin in fine bubbles within seconds, with a slick, almost webbed-hand smoothness typical of Tokachi's moor springs.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A natural moisturizer also used in skincare lotions. Forms a thin veil on the skin to reduce moisture loss after bathing.
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.
At 43.5°C the bath runs slightly hot, so keep full soaks short and alternate with half-body bathing in the shallow area. The pH 9 alkaline water lifts away skin oils, so moisturize afterward, and sit still to enjoy the fine bubbles.
With pH 9.01 alkalinity, 178.4 mg/kg bicarbonate and 106.0 mg/kg metasilicic acid, this gentle simple spring softens the skin's surface for a silky skin finish, and its mild touch invites deep relaxation at the end of a long day.
The alkaline water makes floors and tub edges slippery, so step carefully. The bath is fairly hot—avoid long soaks, stay hydrated, and moisturize afterward.
