Ryuga Cave
龍河洞Kochi · Shikoku
Ryuga Cave is a 4-kilometer limestone cavern in Kami, Kochi Prefecture, formed roughly 175 million years ago, with about 1 km open to visitors along lit walkways past stalactites and an ancient Yayoi-period pot fused into the rock by mineral deposits. A separate caving 'adventure course' lets visitors crawl through unlit passages in overalls and helmets.
