5 Facilities
One minute from the Yudanaka station gate: a free-flowing day bath with two bathrooms (each with an open-air tub) that swap monthly. The lounge overlooks the platform — perfect while waiting for the train back from the snow-monkey park.
Of Shibu's nine communal baths along the cobbled street, No. 9 'Ō-yu' is the only one open to non-guests. Hot rusty-brown water plus a steam room fed by the source; a footbath on the roof. Buy a ¥800 ticket at the tourist office or nearby inns and have the door unlocked for you.
A day-bath facility attached to a coffee shop in the Shibu Onsen street. In a town where the nine communal baths are reserved for overnight guests, it is one of the few places you can soak without staying. The tub is ringed by the old stonework that gives the room its name, filled with clear water that runs straight from the spring with no added water and no heating. A partition divides the bath in two, and the side by the inlet runs very hot. Shampoo, body wash and dryers are provided; 600 yen for adults and 300 yen for children, 10:00 to 18:00, closed Tuesdays. It stands right off the street, which makes it easy to fit between other stops.
A Japanese-modern inn at the centre of Shibu Onsen, where two springs of different character are blended and run flow-through, and day visitors can use them too. Day bathing costs 1,500 yen for adults and 800 yen for elementary pupils (tax included), with a bath towel and a face towel provided. Reception runs 9:00 to 12:00 and 14:00 to 19:00. The great baths close for cleaning at times such as 12:00 to 14:00, and a private loyly sauna opened in 2021. There is a deep tub and an open-air bath, and after bathing you can rest on the first and fourth floors. Overnight guests receive keys for the nine-bath tour.
A long-established inn in the heart of the Yudanaka Onsen district, Yamanouchi, Nagano. Just a 6-minute walk from the Yudanaka Station-front bath Kaede-no-Yu, it is a popular base for visiting the Snow Monkeys of Jigokudani. The inn's bath is open to day bathers too: reception 10:00-17:00 at 500 yen for adults and 250 yen for children - as affordable as the station-front bath. Its appeal is soaking in softly flowing spring water in a quiet inn bathroom, away from the crowds of the station facility. Day bathing may be unavailable with groups or on occasion, so calling ahead (0269-33-2151) is recommended. Combine it with the Shibu Onsen outer-bath tour (Kuban-yu, Oyu and more) for a full day of hopping around the Yudanaka-Shibu spa area.
