Yakushi-no-Yu — the name invokes Yakushi, the medicine buddha — is a simple sulfur spring. The water runs almost colorless and clear, yet carries the faint rotten-egg note of hydrogen sulfide and a trace of sulfur on the tongue. It is alkaline enough for the slippery beauty-water feel, and metasilicic acid is high enough to leave a thin silica film that makes skin feel smoother. Mineralization is light, so the bath stays gentle rather than heavy. The certificate's spring-type indications point squarely at stubborn skin conditions: atopic dermatitis, psoriasis vulgaris, chronic eczema and pyoderma.

About

Kiyotsukan sits right at Kiyotsukyo, a gorge in the Niigata mountains, and its baths lean into that setting. The indoor bath, Yakushi-no-yu (薬師の湯), is a simple sulfur spring with separate rooms for men and women, open to lodging guests at any hour. The outdoor bath sits over the gorge stream and is a private, reservation-only soak booked at check-in, drawing on two separate springs at different temperatures; in winter you can bathe in the falling snow. It's an 11-room ryokan that describes itself as unpretentious and no-frills, guests are welcomed at an irori hearth in the lobby before anything else. The bath's name has a story behind it: it's named for a Yakushi Nyorai statue tied to the Sengoku-era lord Uesugi Kenshin, and the innkeeper's family says they found the spring in 1968 after tracing a faint sulfur smell the statue seemed to point them toward. Kiyotsukan also belongs to Nihon Hitou wo Mamoru Kai (日本秘湯を守る会), an association of secluded hot-spring inns. There's no day-use bathing here, only overnight stays.

The only ryokan in Kiyotsukyō Gorge, famous for the Tunnel of Light, an art installation that tourists are bused in from Tokyo to see. Meanwhile, the ryokan is one of the oldest, and is part of Hitō (hidden hot springs). Everything is traditional, and the staff are Japanese only. More than that, almost everyone there is family, the owners. Dinner is only at 18:00, again, traditionally. The rooms are clean, beautiful, spacious, and there are only 11 in the whole ryokan. The interior is full of old artifacts, photos of visitors from the Imperial Family, and so on. The entrance to that same art tunnel is literally 5 minutes away. Guests do not need a reservation, but they do need a ticket. That is a huge benefit, because you can manage to pop in before the crowds and take great photos. 100% recommended.

Baths. In the ryokan building there is one indoor bath. It closes early at 23:00. Hot, 42. There is a place to wash, there are hair dryers, local drinking water. It smells of sulfur, clear. The outdoor bath is the reason people come here. A separate building right by the river. Reservations only for guests at check-in. Not by phone. The first reservation is free, the second is ¥300. Kashikiri, by the river, with two baths from different (!) sources, one of them cool. 41 and 38. There is nowhere to wash, so you need to go inside beforehand to the indoor bath. A unique place in every sense.

Food. A very tasty kaiseki with an emphasis on local mountain herbs and vegetables. Nothing luxurious, just tasty and varied, exactly as it should be. Of course, the divine Niigata rice. The service is like visiting your grandmother at her dacha, they feed you and take care of you wholeheartedly, and try to give you more rice.
