• This course follows the general visitor route in the RoKando Cave, which is open to the public. The highlight is one of Japan’s largest waterfalls within a cave, Ama-no-Iwato Falls, cascading 29 meters through a marble fissure. The sight of this roaring waterfall in the mystical blue-lit space is truly breathtaking!

At the deepest point of the cave, which stretches a total length of 880 meters, one reaches a mysterious space that expands in a dome shape with a circumference of 50 meters and a height of 60 meters, one of the largest in the Tohoku region.
