Where you feel the breath of the earth
Akiyoshidai is the largest karst plateau in Japan, spread in the middle and eastern part of Mine City.
It was designated as a National Monument (Akiyoshidai Quasi-National Park) in 1955 and a special natural monument in 1964.
The limestone that makes up the magnificent landscape of Akiyoshidai is about 350 million years ago in the southern sea.
It was born as a coral reef, and over the years has formed a karst plateau like today.
Mysterious space created by groundwater
Under the Akiyoshidai base, one of Japan's leading limestone caves is spreading.
Rain falling on the limestone plateau melts rocks through cracks and gaps and flows in, melting rocks underground
As it flows, it becomes hollow.
The cavities become larger and larger, and limestone caves are created.
