Yubara Onsen was created to treat a beloved concubine of Toyotomi Hideyoshi, a great Japanese general and samurai.
Today, it lies in a natural, remote setting in the shadow of a massive dam.
Its stunning outdoor onsen bath, Suna-Yu, is open 24-hours-a-day and located in the riverbed of the Asahi River.
This unique bath is a konyoku, or mixed-gender, and free!
It is surreal in snow, however, the winter snowfall isn’t constant, so check the weather before you go.
