Onigajo (Demon's Castle), Kumano

熊野市 鬼ヶ城

A dramatic coastal rock formation carved by waves and wind over millennia. This UNESCO-listed site inspired the rugged seaside landscapes depicted in Nagi-Asu.

📺 Scene from the Anime

The towering rock formations and crashing waves at Onigajo evoke the boundary between the sea world and the surface world in the anime. The cave-like openings resemble passages to the underwater village.
