Ryūga Cave

Ryūga Cave is a limestone cave in Kami that extends for 4 kilometers through natural passages with impressive rock formations. An illuminated pathway leads visitors about 1 kilometer into the interior, revealing the structure and scale of the underground space.

The cave was designated as a Natural Monument and Historic Site of Japan in 1934. Archaeological excavations revealed pottery and furnace remains from the Yayoi period, along with animal bones from roughly 2,000 years ago.

The name refers to a dragon legend associated with the site, reflecting how local mythology continues to shape how people experience and think about this place.

The cave maintains a steady temperature year-round, making it a good choice during cold or wet weather. Wear sturdy shoes since the ground is uneven and some passages are narrow.

An 11-meter waterfall inside the cave is lit with blue light, creating an unexpected visual experience. This artistic treatment of a natural feature gives the place a character that stands out from other cave visits.
