A simple weak-radon spring rising in a residential pocket of Morioka. Strongly alkaline at pH 9.9, it has the slippery feel of the Japanese beauty-water family. Light overall mineralization (234 mg/kg dissolved solids) is offset by a notable radon load — 121 Bq/kg, well into the hormesis-tradition range. The wellhead runs at 31 C, so the bath is reheated for soaking.
