Amihari Onsenkan Yakushi no Yu is found in Shizukuishi, Iwate Prefecture. Its sulfurous water resurfaces at 44°C and feeds an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Yakushi no Yu, the Medicine Buddha spring, continues the ancient tradition of dedicating restorative hot springs to Yakushi Nyorai, the healing deity invoked by Japanese Buddhists. Amihari Onsen in the volcanic Shizukuishi valley sits at the foot of Iwate-Komaga-take volcano beside the legendary Koiwai Farm — a 3,000-hectare private dairy ranch established in 1891 that has welcomed visitors through four generations beneath the volcanic highland skyline.
