The Kawazu Nanadaru are seven waterfalls in the mountains above Kawazu Town in southeastern Izu.

The waterfalls, ranging from the 30 meter tall Odaru ("large waterfall") to the 2 meter tall Kanidaru ("crab waterfall"), can be viewed from a pleasant walking trail, which leads for about one kilometer through the forest.

Several statues along the walking trail depict the heroine of the short story "Izu no Odoriko" (The Izu Dancer, 1926), one of several works by Kawabata Yasunari (1899-1972), which are set in this area of the Izu Peninsula. Kawabata won the Nobel Prize in literature in 1968.

At the base of the trail you can find the small hot spring resort Nanadaru Onsen and the imposing Kawazu Nanadaru Loop Bridge, a two storied spiral bridge along National Route 414 high above the valley floor
