Classification
Sodium Bicarbonate spring
A sodium bicarbonate spring of the jūsō-sen family, blended from two wellheads (Kaminoyu and Shimonoyu) and emerging hot at 43.3 °C. Weakly alkaline at pH 7.8 with a generous bicarbonate load, it sits squarely in Japan's beauty-water tradition — soft, slippery on the skin even though the water itself is colorless, tasteless, and odorless at the source. Moderately mineralized at 1,502 mg/kg dissolved solids, it is the kind of gentle, skin-smoothing water that earned Ryujin its place among Japan's three celebrated bijin-no-yu springs.
