Ryugado [Kochi]

Ryugado (which means "dragon river cave") is one of Japan's three largest limestone caves. It was developed over 175 million years. The cave is approximately 4 kilometers long, with around 1 kilometer available to the general public. The twists and bends of this extraterrestrial cave reveal stalactites and stalagmites of various sizes. It was designated a Natural Monument of Japan in 1934 for both these spectacular landforms and the 100 distinct creatures that call this unusual ecosystem home, as well as a Historic Site for the Yayoi era vessels discovered here (300 BCE-250 CE).

Colorful lights, projection mapping, and music were added to the main tunnel in 2019 to give this beautiful geological feature a new dimension of wonder. One of the attractions is an 11-meter waterfall illuminated by blue lights and accompanied by special music produced to complement the drops of water splashing lightly against the limestone. Adventurers who wish to discover the cave's mysteries can schedule a guided tour (with with safety equipment!) that will take them to areas that regular tourists aren't allowed to see. In 2021, an unique tour of the neighboring West Water Cave will be added to commemorate the cave's 90-year anniversary. Make a point of visiting the museum on your way out, and leave time to stroll down the retail street that runs up to the cave's entrance, which is lined with chic cafes and boutiques.
