Karesansui, or dry landscape, is a traditional Japanese garden style that uses stones to represent mountains and water. The placement of stones in a karesansui follows certain rules: stones should be placed to suggest natural rock formations, with larger stones representing mountains and smaller ones representing hills or rivers. The arrangement should create a sense of balance and harmony, with consideration given to the perspective of the viewer. The overall composition aims to evoke a sense of peace and tranquility.
