Hotel Osakaya is a small hotel in Yunokami onsen (湯野上温泉), by the Aizu railway line in Fukushima. The rotenburo uses kakenagashi (源泉かけ流し) spring water and swaps between men and women by time slot, while the indoor baths are separate for men and women. There is also a viewing bath you can book privately (kashikiri, 貸切). The water is soft on the skin, and the baths look out over the valley, the mountains and the river below.
