 Events include a fireworks festival in July, a “Karst Walk” in November, and an annual burning off of dry grasses in February called “Yamayaki”.The plateau consists of uplifted reef limestones of Paleozoic age, which were thickened by overfolding during the Akiyoshidai orogenic movement.Subsequent erosion has created an undulating karst landscape dimpled with many dolines and countless limestone pinnacles up to two meters in height.
