About
Sasakura Onsen Ryunso is a single ryokan at the foot of Mount Yakeyama, looking out over rice terraces and a river. It draws on two springs of its own, Ryuun (龍雲) and Yakushi (薬師): the water is soft on the skin, yet strong enough that what overflows from the rock-lined outdoor bath crystallizes on the floor. There's also an indoor bath in a separate wooden building, a private bath you can reserve, and a drinking-water corner where guests take a cup of the spring water, said to be good for the stomach. The inn's history goes back about three hundred years, to when a villager named Sonoda Bunzaemon is said to have opened the spring after a vision of the healing buddha Yakushi Nyorai (薬師如来). A 1914 flood buried the original source, and it took some four thousand local residents more than 800 days of digging to bring it back in 1926.
