Shirasu-Daichi

Shirasu-Daichi is a volcanic plateau in Southern Kyushu formed by thick layers of volcanic ash and pumice particles. The terrain shows a rolling landscape with gentle slopes and natural hollows where the soft material has worn away over time.

The plateau formed through major volcanic eruptions that deposited layers of ash and pumice across Southern Kyushu. Over many centuries, weathering and water erosion gradually shaped the terrain into its present form.

Local farmers have adapted their agricultural methods to work with the volcanic soil composition, developing specific techniques for crop cultivation in the region.

You can explore the plateau on foot or from viewing areas that show the layered structure of the volcanic deposits. The terrain is best visited during dry weather when paths are easier to walk and the features are clearly visible.

The Koya pyroclastic flow deposits extend up to 60 kilometers from their source, maintaining a consistent thickness of less than 2 meters across the plateau.
