An alkaline simple-sulfur spring drawn at 50.9 °C — high-temperature class. The water is near-colorless and clear at the wellhead but carries an unmistakable hydrogen sulfide note, and the 12.4 mg/kg of HS⁻ comfortably clears the sulfur-spring threshold. At pH 8.8 it sits in the alkaline band, soft on the skin in the classic Bessho beauty-water style.

About

Kashiwaya Honten spreads its bathing across three separate areas: a rock-lined indoor bath and a cypress rotenburo (露天風呂) in the main building, two all-cypress indoor baths in the annex, and a free private bath, a stone open-air tub paired with a cypress indoor one, that guests can reserve for a 40-minute soak at check-in. The water is sulfur-scented and known locally for leaving skin silky-smooth, and it can be sipped on request at the front desk. Four of the twelve guest rooms have their own open-air bath and two have an indoor tub, so a soak in private is possible without leaving the room. The ryokan stands right next to Kitamuki Kannon (北向観音), the temple traditionally paired with Zenkoji (善光寺) in Nagano, in Bessho Onsen (別所温泉), an old hot-spring town said to get a mention in the classical Pillow Book (枕草子). Run by the same family for over a hundred years, it keeps a quiet, old-fashioned feel around a small courtyard garden, with kaiseki dinner and breakfast served in private dining rooms.

信州別所温泉 かしわや本店 Рёкан с онсеном. Несколько ванн внутренних, одна снаружи, расписание меняется по сложному графику (на фото). Приватные ванны (внутренняя + наружная) можно бесплатно забронировать при заселении. Часть номеров с ванной на террасе. Вода щелочная, pH 8.8, заметно пахнет сероводородом, в приватной внутренней ванне - хлопья 😅 Дышать во внутренних ванных тяжеловато. Вода горячая, как по мне, особенно внутри, снаружи полегче - и дышать и находиться в воде. Ажиотажа нет вообще, оба раза была в общественных ваннах одна. Сам рёкан - один из лучших, где я была, абсолютно правильное и внимательное отношение - персональная встреча на станции (без бронирования, просто ждут каждый поезд), настоящая матча со сладостями при заселении, подарочки при выселении. Приставили к нам на два дня персонально японку, которая хорошо говорит по-английски, она нам весь кайсеки подробно рассказала и объяснила. Еда в плане гармонии, свежести и сезональности ингредиентов - пять из пяти.
