A steam-generated blended spring fed by the volcanic vapours of Hakone's Owakudani — a hot (source 60.6 °C) acidic calcium sulfate-chloride water. At pH 2.1 it is strongly acidic, sharp enough to sting slightly on contact and long associated with stubborn skin conditions. The water is slightly milky white with a faint hydrogen sulfide note, and a generous 157 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother.

About

Shirayu no Yado Yamadaya (白湯の宿 山田家) sits in Hakone's Gora area and draws its water from the Owakudani volcanic source. The spring runs milky white and faintly sulfurous, and the indoor baths flow fresh without recirculation. Two large bath halls on different floors swap between men's and women's sides a couple of times daily, so staying guests can catch both layouts. On the top floor, a private open-air bath called Ubu-yu (うぶ湯) is available to reserve. The outdoor baths look out over the surrounding mountains and are decorated with Hakone yosegi-zaiku (寄木細工) marquetry woodwork. Meals are served in-room in kaiseki style. No elevator.

182. Yamadaya, Hakone I went for a day-use visit to the baths on the 3rd floor. Day-use is listed from 12:00 to 16:00. On the 4th floor, as I understood it, there are also some private baths. Inside, there is a square bath with milky water and white mineral deposits. The temperature was hot. It was easy to breathe inside. Outside, there are two single-person baths, one round and one oval. I used the round bath, and the temperature there was odd. The overall temperature was hot, but the water at the bottom felt cooler, while the water flowing in near my shoulder was hotter, which was uncomfortable. The ryokan itself looks interesting inside, but overall the baths did not really appeal to me. 12.07.2024
