O-yu (Nozawa outer bath)
大湯(野沢温泉 外湯)
The centerpiece of Nozawa's 13 public baths, a traditional bathhouse in the middle of the village. Local 'yunakama' associations have cleaned it daily since the Edo period; payment is a donation in the box at the door. Two pools, hot and 'mild' — though even the mild one exceeds 42°C. Adding cold water is bad manners: rinse first, then keep soaks short. No soap or shampoo.

More in this area
Jigokudani Onsen Korakukan
A Meiji-era inn at the entrance to the Jigokudani Monkey Park, famous worldwide for wild macaques that climb into its rotenburo in winter. Day bathing is only 12:00–15:00, so most visitors combine it with the monkey park. It's a 30-minute mountain trail from Shibu Onsen — wear grippy shoes in winter.
Shirahone Onsen Awanoyu
The signature inn of Shirahone, famous for milky-white water. Its highlight is a large mixed-gender open-air bath — the water is so opaque that women find it comfortable. Day use at midday only.
Yudanaka Ekimae Onsen Kaede-no-yu
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.
