An acidic calcium sulfate-chloride spring fed by a steam-generated blend from Owakudani. At pH 2.1 the water is sharply acidic, prickling slightly on the skin, and it carries a faint milky turbidity with a light hydrogen sulfide note. A generous 157 mg/kg of metasilicic acid leaves the kind of thin silica film that makes skin feel smoother. It is served without heating, recirculation, disinfection, or bath additives — only diluted with water for temperature control.

About

Mount View Hakone sits in the Sengokuhara area of Hakone and is known for its milky-white sulfur water, which is relatively rare among ryokan in the Kanto region. The shared outdoor baths (Kawara-no-yu, 川涌の湯) are separated by gender and run free-flowing. There are also three private rotenburo that guests can reserve on the day of arrival. An indoor bath rounds out the bathing options. Day-use soaking in the shared baths is available.

172. Mount View Hakone ★ I went for a day-use visit for 1200. The listed hours are 11:00 to 15:00. The website also says there are private baths from 11:00 to 14:00 for 4000 (I did not use them). It is in the northern part of Hakone. Judging by the water temperature, it seems to have a special summer schedule. Inside, there is a bath with clear water, and the temperature is 34-36. It is comfortable to breathe inside. The outdoor bath is set in stone, with a pleasant view of greenery and a bit of bamboo. There were two insect traps that smelled bad. The water is different from the indoor bath, cloudy white with fine white mineral deposits, and the temperature is 41.5 (the staff member's grandfather took the measurement). The photo of the bath itself is from the website, and it matches. A good place, with different water in the baths and a nice outdoor bath. 11.07.2024
