Ryokan Daikokuya sits in a gorge in the Abukuma highlands of Fukushima, and its centrepiece is a cavernous rock bath (大岩風呂, oiwa-buro) reached by crossing a small bridge over the river. The water comes from two different springs, a simple alkaline type and a calcium-sodium sulfate type, both around 45 degrees and served kakenagashi. The deep, wide tub carved into the rock and the snowy winter scenery outside make this one of those baths that stays with you.
