Dry landscape, also known as 'karesansui,' is a traditional Japanese garden design that features carefully raked sand or gravel arranged to symbolize rocks, mountains, and water. The indoor version of this landscape typically involves replicating this minimalist style in an indoor space, often with the use of artificial grass or sand, and incorporating small, symbolic elements like rocks and miniature trees. This style emphasizes the beauty of simplicity and the tranquility of nature.
