みさかの湯

Misaka no Yu
Sampled at wellhead
湯
Simple
Classification

Sodium spring

A simple thermal spring in Misaka-cho, Fuefuki city. Strongly alkaline at pH 9.34 — slippery on the skin and sitting squarely in Japan's beauty-water family. Lightly mineralized (720 mg/kg dissolved solids), so the chemistry is gentle on the body; the wellhead runs hot at 51.8 °C and is pumped to surface.
