Insider tip — Tenryu Onsen Okiyome no Yu sits in the forested Tenryu River valley, a region where soft bicarbonate waters have been used for purification rituals for centuries. The name Okiyome evokes spiritual cleansing, and the waters leave skin noticeably smooth thanks to their alkaline composition. Surrounded by dense cedar forest, the outdoor bath offers a meditative view of the river gorge below. The remote mountain road leading here adds to the sense of arrival and discovery.
