Travel Guide - Ryusen-do Cave


Located at the foot of Mt. Ureira-san, Ryusen-do Cave is one of the three largest stalactite grottoes in Japan. The cave is over 3,100 meters long, but the full picture of the cave is still uncertain and it is said that the total length of the cave would be over 5,000 meters.
Noteworthy is a small lake at the bottom of the cave, 120 meters deep, filled with crystal emerald green water called "Dragon Blue".
