A sodium-led bicarbonate spring with a salty chloride edge, of the classic jūsō-sen (soda-water) family. At the source the water carries a faint yellow-brown tint, a slightly salty taste, and a faint hydrogen sulfide note. With 153.7 mg/kg of metasilicic acid it leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
