4 ryokan in Karuizawa on Aitayo have guest rooms with their own open-air bath.
A guest room with its own open-air bath means you do not need to use the shared bath at all. That is a fact about the room, not about any ryokan's policy.

About the shared baths
Rules for the shared baths differ from ryokan to ryokan, and Aitayo has not checked them. If you want to use a shared bath, please ask the ryokan directly.
