Stone is the most familiar heavy material. Every field in satoyama is paved with stones in a terraced pattern, and every time I see a stone wall, I am impressed by the greatness of people in the past. The use of natural stones, such as bundling stones and weighted stones, can be observed on a daily basis.

Stones are also used as objects for special religious beings, such as Dosojin, Jizo, and stone monuments.

It is obvious that stones from the mountains have a cracked and jagged appearance, while stones from the riverside have rounded corners.
