This lodging sits alongside a river with such ferocious rapids that you might feel you're being plunged right into the drama of nature on arrival. Most of the rooms are new and modern and overlook the river, so you can always hear the rushing waters. There is a rotemburo (outdoor hot spring) for mixed bathing that sits on the edge of the river and another private outdoor hot-spring pool that you can book in advance—both are wonderful. After bathing, enjoy an incredible full-course Japanese dinner (that and breakfast are included in the rates). The ingredients in both meals are fresh and varied according to season and cooked to the highest standard. Vegetarian options are available.
