Riverside Beauty Spring

Ryujin Onsen is an ancient spa said to have been discovered by the ascetic En no Gyoja and opened by Kobo Daishi after a dream of the dragon king Nanda; in the Edo period it was a favored retreat of the lords of Kishu. Shimo-no-yu flows naturally beside the Hidaka River, and its bicarbonate-rich water gently lifts away old skin, leaving a silky feel. Counted among Japan's three great beauty springs, it has long welcomed travelers seeking smoother skin.
