Explore the underground depths of the 175-million-year-old limestone caves
Kochi Prefecture
Kami City, northeast of Kochi City, is home to one of Japan’s three largest limestone caves, forged over 175 million years ago. Designated as a Natural Monument, Ryugado Cave is approximately 4 km long, 1 km of which is open to the general public.
Recently, colored lighting, projection mapping, and music were installed throughout the main tunnel, adding an additional dimension of wonder to this geological formation. For those who are looking for a slightly more active caving experience, try the Adventure Course tour that involves both safety gear and a spelunking guide (reservation is required).
In 2021, to celebrate the 90-year anniversary of the opening of the cave, a special tour of the nearby West Water Cave was added. The temperature in the cave tends to stay the same year-round, so it feels warm in the winter and can be enjoyed even on a rainy day. Cave activities are only available at certain times. The tour is available from April 29 to the end of September.
How to get there
From Haneda Airport, fly to Kochi Ryoma Airport (about 1 hour 30 minutes), then drive for about 15 minutes to the destination.
