Mitsugo Limestone Cave 三ツ合鍾乳洞

Yozawa 1075 Akiruno-shi Tokyo

Descend into the darkness of subterranean Tokyo

A visit to Mitsugo Limestone Cave is often made in conjunction with the larger Otake Limestone Cave just a 10-minute walk down the road. This cave is about 100 meters in its entirety and takes you about 20 minutes to walk through. You enter down a steep steel staircase wearing a helmet with a light that you borrow from the visitor center.

Along the way you'll encounter interesting geological features with creative names like the Arora Ceiling, named for its cascading patterns. There's also a small waterfall dedicated to a dragon god and praying there is said to bring long life. Take this opportunity to explore another world below Tokyo's surface.
