Hiraodai Limestone Plateau is counted among the 3 major karst formations in Japan and has been designated a natural monument, a quasi-national park, and prefectural natural park.
There is scenery to be enjoyed in each of the 4 seasons, including the burning off of fields in spring, the new greenery of summer, and Japanese pampas grass in fall.
