Ryusendo Cave

This massive limestone cave is one of Japan’s three largest, and is designated a National Natural Monument. The cave is over 5,000 meters long overall, and hosts eight underground lakes that are among the clearest in the world. The color of the water, called Dragon Blue, is astonishing and the mystical sight is worth visiting. A 700 meter walking route in the cave and three of the eight lakes are open to the public. One section of the trail is barrier-free, with full wheelchair access. The limestone filtered water has been named one of Japan’s top 100 waters, and is available to drink at the cave entrance.
