A sodium-led bicarbonate spring — the classic juso-sen (soda-water) style, soft on the skin. At the wellhead it runs colorless and clear with abundant gas evolution, and in the lab it carries a faint hydrogen sulfide note. Weakly alkaline at pH 8.4, it sits in the Japanese beauty-water family thanks to its bicarbonate dominance and slippery feel.
