Spectacular hot spring and self-löyly sauna overlooking Lake Hamana
Shizuoka Hamamatsu City
"Hotel Harvest Hamanako" is a resort hotel nestled on the shores of Lake Hamana in Hamamatsu, Shizuoka Prefecture. Its biggest draw is the natural hot spring, where you can enjoy beautiful panoramic views of Lake Hamana. The mildly slippery alkaline low-temperature spring can be enjoyed in the open-air bath and tsubo-yu. The large bath also features a full-fledged dry sauna with self-löyly, an individual-sized cold plunge bath, and an outdoor bathing area equipped with infinity chairs in some sections, allowing you to enjoy both a resort stay and an authentic sauna experience at the same time.
