This limestone cave 20km northeast of the city of Kochi has a labyrinth of white walls and columns. A total of 24 tunnels are criss-crossed in 4km in total length, 1km of which is open to the public. You can take a 30-min ordinary route, or a 90-min adventure route with reservation, to view pillars up to 10m in height and 4m in diameter.
Some streams on the slopes of Mt Sampo flows down 60m underground, forming 20 or so waterfalls in the cave. This place was home to early men about 2000 years ago, and plenty of artifacts including earthenware have been excavated here. The cave is one of Japan's three major limestone caverns, along with Ryusendo in Iwate and Akiyodo in Yamaguchi.
