The majestic view of countless sea-eroded caves of various sizes, formed by the rough waves of the Kumano Nada, cascading down in a stair-like formation is absolutely breathtaking.
Onigajyo is a coastal scenic spot located in Kiboncho, Kumano City, Mie Prefecture, and is known as part of the national place of scenic beauty, "Kumano no Onigajyo, including Shishiiwa" (熊野の鬼ケ城 附 獅子巖). Countless sea-eroded caves, carved over many years by the relentless waves of the Kumano Nada, are arranged in a stair-like formation due to an earthquake-induced uplift. This magnificent spectacle stretches approximately 1.2km along the Kumano Nada coastline, offering a breathtaking view. Its name, "Onigajyo" (Devil's Castle), comes from its resemblance to a fortress built by ogres. Legend has it that Sakanoe Tamuramaro conquered the pirate Taemaru, who was feared as an ogre, at Onigajyo. The Onigajyo hiking course extends from the east entrance to the summit. In spring, four types of cherry blossoms bloom successively, providing a prolonged cherry blossom viewing experience. Designated as a national place of scenic beauty and natural monument, Onigajyo is also registered as part of the UNESCO World Heritage site, "Sacred Sites and Pilgrimage Routes in the Kii Mountain Range." It is also selected as one of Japan's Top 100 Views, making it a popular tourist spot where you can feel the power of nature and sense the weight of history. When visiting Onigajyo, please wear comfortable shoes, stay well-hydrated, and prioritize safety during your walk.
