Sakura-shi Dai Ichi Onsen Yokujo, also known as Motoyu Onsen, is located in Sakura city, Tochigi Prefecture. The sodium-chloride water reaches 41°C here, with an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Motoyu Onsen serves the Kitsuregawa district of Sakura City, where riverside rotenburo outdoor baths beside the Houki River are among Kanto most unexpected rural spa experiences. Kitsuregawa Onsen is one of the very few natural hot spring areas in the Kanto plain, and the outdoor baths overlooking rice paddies and bamboo groves in this remarkably undisturbed Tochigi agricultural landscape offer a profoundly different experience from the resort hot springs of the mountains.
