Discover more about National Natural Monument Onigajō Cliff.

Onigajo Cliff, a designated National Natural Monument, presents a captivating landscape born from over 14 million years of geological activity. Part of the Yoshino-Kumano National Park and a component of the Kumano Kodo pilgrimage route, this 1.2 km stretch of coastline reveals the powerful artistry of nature. Volcanic rock, shaped by relentless erosion and uplifted by earthquakes, has formed a rugged cliff face dotted with caves, sharp rocky points, and honeycomb-like patterns. Legend intertwines with the natural formations, giving Onigajo its evocative name, "Demon's Castle". Tales speak of pirates and demons inhabiting the caves, adding a layer of mystique to the site. According to one legend, Sakanoue no Tamuramaro, a military commander, was sent by the Emperor to defeat a pirate named Tagamaru, who was considered as evil as a demon and was hiding in the caves. The cavities were originally called “Oni no Iwaya” or demon’s cave. Visitors can explore the cliff via a narrow path, enhanced with barriers and chains for safety, that winds along the headland. The trail leads to Benten Shrine, offering stunning views of the sea, especially during the afternoon. The site also holds historical significance with the ruins of a 16th-century castle built by Arima Tadachika, offering a glimpse into the region's feudal past. Located near the Onigajo Tourist Center, which provides restaurants and souvenir shops, Onigajo is easily accessible and offers an unforgettable experience of Japan's raw coastal beauty.
