A sodium- and magnesium-led bicarbonate spring, with the soda-water softness of the jūsō-sen family layered with magnesium body. Weakly alkaline at pH 7.6 and soft on the skin, it sits in the Japanese beauty-water family. A generous 243 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards. At the wellhead the water is pale yellow and clear, with a faint metallic, iron-like note on the tongue and nose.

111. Beppu Hosenso, Beppu Visited for higaeri (listed hours 15:00-21:00) for 500 in the indoor bath. Stamp given. Inside there's a large old standard hotel bath. Clear water, temperature is hot. Breathing is tolerable. There also seem to be private baths available by separate reservation — didn't go for one. Unless you're going for stamps, you can skip this one.
