The length of the cave is about 4km, of which about 1km is open to the public as a tourist course. On the sightseeing course, you can enjoy various natural formations of stalactites, such as the huge 11-meter-tall stone pillar “Amaraishi” and the “Tamadare Falls” carved by the flow of water.

Also, in the cave, the ruins of caves and Yayoi-style earthenware that were said to have been used in the Yayoi period have been discovered. Ryugado Cave is a valuable tourist spot that combines natural beauty and historical value.
