Natural Sculptures and a Mysterious Underground Landscape
Inside the cave, visitors can admire a variety of stalactites and other limestone formations created by abundant underground water over long periods of time. These natural sculptures form an impressive subterranean landscape, revealing the beauty and power of nature at work.
The highlight is the 30-meter-high underground waterfall at the cave’s deepest point. Considered one of the largest underground waterfalls in Japan, it is the feature from which Otaki Limestone Cave takes its name.
The Underground Waterfall
The waterfall, located at the far end of the cave, plunges approximately 30 meters through the underground cavern. Its impressive scale makes it one of the most remarkable sights along the route.
The Wooden Cable Car
A wooden cable car operates between the reception area and the cave entrance, transporting visitors up the steep forested slope. The exit is located separately from the entrance, allowing visitors to follow the sightseeing route through the cave.
