Insider tip — Chomonkyo Onsen Yunose is set within the spectacular Chomon Gorge (Chomonkyo), a national scenic area in Yamaguchi Prefecture carved by the Abu River through limestone formations. The bicarbonate waters are gentle and skin-softening, complementing the dramatic canyon scenery of deep green pools and ancient rock walls. Autumn foliage transforms the gorge into a vivid red and orange spectacle, drawing visitors from across western Japan. The onsen's riverside location means you can hear rushing water while soaking in warm mineral baths.
