Shuzenji Onsen is a historic hot spring town on the Izu Peninsula in Shizuoka Prefecture, centered on the Katsura River and the Buddhist temple Shuzenji, built in 807. According to legend, the monk Kobo Daishi (Kukai) founded the springs by striking a rock in the riverbed with his walking staff (tokko), releasing hot water at what is now the town's symbolic outdoor bath, Tokko-no-Yu, in the middle of the Katsura riverbed. The spring water is a mild, alkaline-leaning simple thermal type, known for being gentle on the skin.
Local tradition attributes the founding of both Shuzenji Temple, built in 807, and the hot spring itself to the Buddhist monk Kobo Daishi (Kukai), who is said to have struck the riverbed rock with his ritual staff to release the waters that still form Tokko-no-Yu today. This makes Shuzenji one of the oldest documented hot spring towns on the Izu Peninsula.
