Takaragawa Onsen OsenkakuTakaragawa Onsen Osenkaku is a jewel of an onsen hidden along the Takaraga river. The traditional and charming pinewood lodge was built in 1955 under the shade of cherry trees and later expanded. The spa boasts four large outdoor thermal pools and two indoor baths, as well as the largest open-air bath in Japan. But despite the pools’ roomy capacities, Takaragawa’s remote riverside location makes it an utterly tranquil destination.
