Nestled amid the mountains of Koriyama reside a beautiful series of illuminated limestone caverns. Each chamber is filled with an assortment of colors, ranging in different shades of green, blue, and pink.
The caverns were discovered in 1969 and were formed over 80 million years by the flow of underground streams. The entire cave complex stretches more than 9,000 feet (2,000 meters). A little more than 2,000 feet (800 meters) of the caves are open to the public to explore. The path within the caves is mostly platformed, making navigation relatively comfortable.
