BATHING TIPS
AI Generated

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.

EFFECT STORY
AI Generated

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.

CAUTIONS

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.
