Enclosed indoor bathing area
Shared bathing area for all genders
No mixed bathing mentioned; the small ryokan runs ordinary separate men's/women's baths.
Asanoya is a small, quiet ryokan in Gero onsen, with separate indoor baths for men and women. The water is soft and silky, the kind that leaves skin feeling smooth, drawn from Gero's springs, an area often named as one of Japan's three great hot spring towns. The building shows its age, but guests describe recently renovated rooms and baths, kept clean, and steady, attentive hospitality from the innkeeper and kitchen.
