Fukuroda Onsen (Sekisho no Yu) is a hot spring facility in Daigo, Ibaraki Prefecture, near the famous Fukuroda Falls. The sodium-chloride water reaches 41°C, pH 7.3. An indoor bath, an outdoor rotenburo bath and a sauna are on offer.
Insider tip — Sekisho no Yu, the checkpoint hot spring, recalls the Edo-period toll barrier on the Mito Kaido road that controlled passage through the Abukuma highland passes into the Naka River gorge. Fukuroda Falls nearby was a compulsory stop on the feudal circuit pilgrimage routes, and the checkpoint theme evokes the gateway function this valley played in the spiritual and commercial geography of eastern Japan for over 300 years.
