Kusatsu Onsen Yubatake open-air inn Nushiyu Ryokan

Nushiyu places bathing at the center of a Kusatsu stay. Its open-air bath looks toward the Yubatake, connecting the soak to the steaming landmark that shapes the town. The inn draws on the Shirahata source, giving the water a more specific identity than a general promise of hot-spring bathing.

The spring is used on a freely flowing basis. Indoor and family bathing facilities complement the outdoor bath, while fourteen rooms keep the accommodation on a manageable scale. The surroundings are traditional and relatively straightforward, allowing the source and outlook to take the lead.

Meals are served in a shared dining hall. Positive food and hospitality feedback adds substance beyond the bath, making this a balanced option for guests who want to stay close to Kusatsu’s defining feature. Choose Nushiyu for the connection between town, source and open-air water rather than an isolated private retreat.
