Iwaso is a ryokan in Iwaki Yumoto where the main bath is a shared large bath (daiyokujo, 大浴場) on the top floor. It is walled in glass and looks out over the roofs of the onsen town. The bath is filled with natural onsen water, and there are no private baths to book, so bathing is in the shared bath. Shampoo, conditioner and body soap are provided. Tattoos are not accepted in the bath. Free parking is available.
