Hidden beneath the cliffs, the Sandanbeki Cave is a vast sea cavern where history and legend meet. It is said that the Kumano Suigun, the naval warriors of medieval Japan, once hid their ships here. As you descend, the roar of waves and the spray of saltwater fill the air, revealing the immense force that shaped this natural wonder. Smooth rock walls and tide-worn formations trace the marks of endless collision between water and stone. Illuminated pathways lead you deep inside, where you can feel both the ancient power of the Pacific and the spirit of the people who once braved it—a living story of nature’s strength and human resilience.

Towering above the deep blue Pacific, the Sandanbeki Cliffs form one of southern Wakayama’s most dramatic coastal views. Stretching nearly two kilometers, these layered sandstone walls were sculpted by waves and wind over millions of years. Their name, meaning “three-tiered walls,” reflects the cliffs’ distinct formation that looks like a giant staircase carved by nature. Standing at the edge, you can feel the ocean’s raw energy and understand why sailors and locals have revered this site for centuries. Once a vital landmark for navigation and a symbol of Kumano’s maritime culture, Sandanbeki remains a breathtaking reminder of the dialogue between the sea’s power and the Earth’s artistry.

Just a short walk from Sandanbeki lies Senjojiki, a vast sandstone terrace whose name means “a thousand tatami mats.” Its wide, flat surface, formed by waves and wind, stretches toward the Pacific like a natural stage. The rock’s graceful curves and layered patterns change color with the shifting light, from gold to amber to soft gray, making it a favorite spot for photography and quiet reflection. Here, the rhythm of waves and the ocean breeze create a sense of timeless calm. Senjojiki is more than a viewpoint—it is a living sculpture, shaped by the sea and sky into one of Wakayama’s most poetic coastal landscapes.
