Insider tip — In the mountain village of Oguni in Niigata's border highlands with Yamagata, Awanoyu (foamy/effervescent spring) rises from deep geological strata that have produced hot springs since the Edo period; the Miyoshiso inn tradition carries the warm hospitality of Niigata's rural mountainous interior, where winter snow transforms the landscape into the pristine Snow Country of literary fame.
