Classification
Sodium Bicarbonate-Chloride spring
A blend of Totsukawa Onsen's No.2 and No.7 wells, this is a sodium-led bicarbonate spring — the classic jūsō-sen style — with a salt-tinged finish from a chloride sub-type. Soft on the skin, it sits in the Japanese beauty-water family, the water colorless and clear but carrying a faint sulfur note at the source. It emerges hot, at 58 °C, among the warmer natural sources.
