Mikaeri Onsen Saika no Yu is located in Shiobara, part of Nasushiobara city, Tochigi Prefecture. The sodium-chloride spring surfaces at 42°C, serving an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In the legendary Shiobara hot spring valley known since Heian times, Saika no Yu occupies a hillside with valley views so beautiful guests instinctively look back (mikaeri) as they depart; the gorge scenery reaches its peak beauty during mid-October autumn foliage when the maple canopy ignites in crimson and gold.
