土石流となって流下した流紋岩（花崗斑岩）などの風化コアストーンを積み石に利用して、何段もの棚田が築かれています。棚田が築かれている範囲は、斜面の傾斜が比較的緩やかな熊野層群の分布域です。

Many terraced rice fields have been built using weathered core stones such as rhyolite (granodiorite) that flowed down as a debris flow. The area where the rice terraces are built is the distribution area of the Kumano Group, where the slope is relatively gentle.
