Classification

Sodium Bicarbonate spring

A hot (43.9 °C) sodium bicarbonate-chloride spring — the soft, skin-smoothing 'jūsō-sen' style with a salty chloride finish layered in. Neutral pH and a moderate 2,356 mg/kg of dissolved solids give it body without heaviness, and 65 mg/kg of metasilicic acid sits firmly in beauty-water territory, leaving skin noticeably smoother after a soak.

One bath at temperature around 42, the second at 40. Breathing is fine. Outside: stone bath with clear water, temperature around 40. Separate stone cold bath.
