A sodium-dominant bicarbonate spring in the classic soda-water (juso-sen) style — sodium accounts for close to 88 percent of the cations and bicarbonate for 93 percent of the anions. It runs neutral and soft on the skin, which places it squarely in Japan's beauty-water family, and at 2,457 mg/kg of dissolved solids it carries enough mineral body to feel substantial rather than thin. Straight from the wellhead the water is colorless and clear but carries a faint metallic tang and a trace of sulfur on the nose; by the time the sample reached the lab a day later, the smell had gone.
