Ryuga-do is a limestone grotto, meandering inland for 4 kilometers (1 kilometer is open to the public). It took 175 million years to become what Ryuga-do is now, and the limestone formations make for fine geological specimens. A number of dishes, presumably used by the prehistoric residents, have also been unearthed in the cave. The cave is protected as a natural monument as well as a historic site.
