Kawazu Nanadaru Onsen is located in Kawazu Town, Kamo District, Shizuoka Prefecture along National Route 414, forming part of the Kawazu Onsenkyo — the seven-spring hot spring group of Kawazu — a thermal cluster on the Izu Peninsula whose collective identity encompasses a series of distinct spring sites distributed across a scenic river valley famous for its early-blooming Kawazu cherry trees that attract visitors from across Japan each February. The spring occupies its place within the Kawazu seven-spring count, which in some classifications is subdivided differently — distinguishing Otaki and Nanadaru as separate springs within the seven-spring group — reflecting the nuanced Japanese tradition of counting and naming hot spring clusters with careful attention to the distinct geological and topographic character of each individual source. Kawazu Nanadaru Onsen contributes to one of the Izu Peninsula's most distinctive thermal landscapes, where the combination of early cherry blossoms, multiple spring sources, waterfall scenery, and the mild Izu coastal climate creates a destination of exceptional seasonal beauty and geothermal variety.
