Oniga-jo: The Demon Castle That Has Unique Rock Formations & Breathtaking Views Of The Sea

Oniga-jo in Mie


Located in Mie Prefecture, Oniga-jo (鬼ヶ城; demon castle) is a natural rock wall that stretches across the coastline of Ise-Shima for 1.2km. Its uniquely beautiful rock formations have led to its recognition as a UNESCO World Heritage Site in 2004, as part of the Kumano pilgrimage route in the Kii Mountain Range.

According to the official promotional website for Oniga-jo, there used to be oni (鬼; demons) that dwelled on these very rocks. The oni caused turbulent waves and tempestuous winds that shaped the rocks to be what they are today.

If you wish to see the beautiful rock formations in their full glory, be sure to visit Oniga-jo during a clear, sunny day. Pro tip: you can avoid the crowd if you visit Oniga-jo early in the morning.

Since the rock formations were formed naturally, do be careful while hiking as the ground will be uneven. Remember to wear comfortable shoes and bring a hiking stick with you should you need it.

Keep an eye out for the unique honeycomb patterns on the ceiling of the caves – they were formed as a result of wind erosion. With the natural light of the glaring afternoon sun seeping into the caves, the rock formation frames a spectacular view of the Kumano ocean.

After the sun sets, Oniga-jo takes on a whole different vibe as countless stars adorn the night sky. Even if you get whisked away by an oni, the exquisite view might just make up for it.
