Along with Arima and Dogo, this premier Kansai hot spring resort has a history of over 1300 years as one of the Three Ancient Hot Springs of Japan. Saki no Yu, a natural open-air bath built on rocks where the rough waves of the vast Pacific crash against the shore, offers an overwhelming sense of openness as if you were becoming one with the sea, and is hugely popular with international visitors as well. It is one of Japan's most iconic ocean-view hot spring destinations, combining resort areas such as the beautiful white-sand Shirarahama beach with a historic celebrated hot spring that even appears in the Nihon Shoki.
