Hiraodai is one of the most well-known karst plateaus in Japan, and offers fascinating views of limestone.
The largest karst plateau in Kyushu stretches from Kokura City to Yukuhashi City, 11 kilometers from north through south, 2 kilometers east through west, and its altitude is around 400 - 600 meters.
Since the white limestones scattered on the green field look like sheep, the plateau is also called "Yogunbaru (sheep meadow)".
There are also a number of calcareous caves here, and the most famous one is Senbutsu calcareous cave, designated as a national natural treasure of Japan.
