Osezaki, which projects out into Suruga Bay, is a sand spit formed by the accumulation of rocks and sediment carried by the ocean currents along the coast. At the tip of the sand spit is a freshwater divine pond, which is said to be one of the seven wonders of Izu. The giant juniper tree, estimated to be more than 1,000 years old, has withstood harsh environments and multiple tsunamis. On the west coast, you can observe the accumulation of lava flowed out by the Osezaki volcano and a cross-section of the Osezaki South Crater.
