Classification
Sodium Bicarbonate spring
A cold-mineral source at 19.5 degrees in the Ryujin area of Tanabe, Wakayama, heated for bathing. The water is alkaline at pH 8.7 and lightly mineralized at 712 mg/kg dissolved solids — bicarbonate is the dominant anion (around 77 percent by mval) and sodium the dominant cation, but every value sits below the therapeutic-spring thresholds, so the certificate qualifies the source as an onsen under the Article 2 fluoride and sodium-bicarbonate provisions rather than as a therapeutic spring. Colorless, odorless and tasteless at the wellhead, with a fine sparkle of bubbles on emergence.
