Located in the Mt. Ryozen karst region, the entrance to this limestone wind cave is only 1m high. Once inside, however, a three layered cave complex spreads away, including many small chambers and a total area of 1544 square meters, making it one of the largest such caves in the entire Kansai region. You can take a tour of the first and second levels, traveling about 200m from the entrance. As the temperature inside the cave remains around 12℃ to 13℃ throughout the year, it is cool in summer and warm in winter.
