Karesansui, or dry landscape gardening, is a traditional Japanese garden style that uses stones, sand, and gravel to create a representation of natural landscapes. The design often emphasizes simplicity and the contemplation of nature. In indoor design, karesansui elements can be incorporated to mimic the serene and minimalist aesthetic of this traditional style. This involves arranging stones to represent mountains and using sand to symbolize water, all within a controlled space that encourages mindfulness and tranquility.
