About 1,100 years ago, Jikaku Daishi, the priest who pioneered Osorezan, got lost when he was traveling to Oku-Yagen, fell from a cliff and hurt himself. A kappa (water imp) appeared from nowhere and carried Jikaku Daishi away on his back. The next morning when the priest awoke, he found himself covered with butterbur leaves and in the warm bath. He was surprised to find that his pain was gone. Daishi was so grateful to the kappa that he named the hot springs Kappa-no-Yu.
