About
A small family-run minshuku in Norikura Kogen, with milky white sulfur water. Reviewers describe it coming straight from the source, unheated and undiluted. There are two indoor baths, one for men and one for women, and a reservable private outdoor bath, kashikiri rotenburo (貸切露天風呂). The water is kept a little on the cool side, nuruyu (ぬる湯), rather than hot.
