Supreme moor lukewarm bath and a perfectly arranged flow between sauna & cold plunge
Yamanashi Yamanashi City
Shotokuji Onsen Hatsuhana in Yamanashi City is a day-use onsen attached to a restaurant with a history of eel farming. Its greatest attraction is the amber-colored, plant-derived moor spring. You can soak for as long as you like in the flow-from-the-source lukewarm spring at about 34°C, which clings to and moisturizes the skin. The sauna located in the outdoor area offers a perfect flow to a drinkable, crisp 17°C groundwater barrel bath, a spacious 23°C cold plunge bath, and the outdoor cooling/rest area. This renowned hot spring lets you enjoy onsen bathing, sauna, and exquisite eel cuisine.
