Takaragawa Onsen is one of the well-known konyoku onsen. It is located not far from Minakami Onsen (Gunma), deep in the mountains. Both day use and overnight stays are available. The baths are spread along a fast-flowing mountain river, with views of the forest and mountains. It has a very atmospheric, local feel. Since the baths are large and not heated, the water away from the source is cool. It is great for summer, but in winter it can feel chilly. For day use, there is not really a proper place to wash yourself. Konyoku: all but one of the baths are mixed bathing, except for one women-only bath. Clothing is required and included in the price. Definitely recommended to visit.
