Ogawa Spring
Analysis UnverifiedOgawa Onsen is a naturally gushing thermal spring nestled quietly in the mountain villages of Toyama Prefecture, cherished by local residents for generations. This neutral-pH spring envelops the body in a gentle warmth, making it an ideal sanctuary for those seeking respite from daily fatigue or nursing cold sensitivities and digestive complaints.
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 a blend of chloride and bicarbonate mineral waters, Ogawa Onsen feels exceptionally skin-friendly and invites extended soaking—yet note the source temperature reaches a robust 53.5°C. Begin with brief 3–10 minute immersions initially; once acclimated, extend to 15–20 minutes. After bathing, gently pat dry without rinsing away the mineral film, then rest in a warm environment for 30 minutes to lock in the thermal benefit.
With 337 mg/kg sodium and 387 mg/kg chloride content, the spring's minerals coat the skin in a protective film while diffusing warmth deep into the body core, addressing cold sensitivities and peripheral circulation disorders. Bicarbonate ions (363 mg/kg) smooth and refine skin condition, simultaneously supporting fatigue recovery and gastric-intestinal wellness. At a bathing temperature of 42°C, this spring proves especially beneficial for easing chronic joint and muscle stiffness, alleviating everyday stress, and promoting restorative sleep.
Avoid bathing if experiencing fever, active tuberculosis, severe cardiac or renal disease, or gastrointestinal hemorrhage. The facility employs continuous sodium hypochlorite sanitization; guests with sensitive skin are advised to rinse with warm water post-bathing.
