Tsurunoyu Onsen

Honjin (本陣) — the thatched guard house

Five rooms with an irori hearth, toilet and kerosene lamp, each entered from outside — the classic Tsurunoyu experience, from about ¥15,550 per person with two meals. A solo guest in 2025 found one only by phoning after the website showed it full six months ahead. Note the doors can't be locked from outside, so use the free lockers for valuables.

Shin-honjin and Higashi-honjin

The comfortable option (about ¥17,750–24,350 per person): toilet and washbasin, warm in winter, and some rooms (Shin-honjin 5, Higashi-honjin 1 and 5) have an irori. They're in the same building as the guests-only indoor bath and the private baths, so you don't have to go outside in the snow.

Wings 2 and 3 (2号館・3号館), if you want comfort

The cheapest rooms (about ¥11,700 per person) are 6 tatami with no toilet — shared toilets and a ground-floor washroom that one January guest found poorly heated, with icy tap water. The steam heaters are powerful, but there's no air conditioning or fan for summer, and thin fusuma let in the sound of people going to the 24-hour baths. Meals are served in honjin rooms rather than your own.

Wing 1 (1号館) — renovated, but meals in the main hall

The inn's booking plans say Wing 1 has been renovated with a toilet and washbasin, and the official room page, updated in October 2026, no longer lists it as toilet-less. Its three rooms are all on the second floor, from about ¥18,080 per person, and meals are served in the main hall rather than in your room.
