Ryusendo Cave is one of the Three Great Limestone Caves in Japan and a national natural monument. The portion of the cave which has been explored stretches over 3,100 meters; if unexplored areas are included, the entire cave is estimated to be over 5,000 meters in length. You can take a tour of the cave, which takes about 30 minutes. In the cave, fresh spring water forms deep underground lakes; the most impressive is the third lake, with a depth of 98 meters and beautiful emerald-green water. Though it is not included in the tour, the fourth lake is the deepest underground lake in Japan ( 120 meters ) and one of the most transparent lakes in the world. You can also see unique formations such as stalactites and stalagmites, as well as rare long-eared bats. In December 2009, underwater exploration beyond the third lake was conducted for the first time in 41 years.
Photos are allowed in the cave. No photos in the Ryusenshindo Science Museum.
