Okunakayama Kogen Onsen Asashu no Yu is set in Ichinohe-machi, Iwate Prefecture, on a highland plateau in northern Japan. Sulfurous water reaches 43°C, shared between an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — On the Okunakayama Highland deep in the Kitakami Mountains of northern Iwate, Asashu no Yu (morning rain waters) captures the misty freshness of high-altitude Tohoku dawns; the remote plateau setting near the ancient Jomon archaeological sites of Ichinohe creates an atmosphere where the geothermal earth and the prehistoric past feel tangibly connected.
