Japanese dry stream landscapes, also known as 'karesansui' or 'dry riverbeds', are a traditional form of Japanese rock garden design. They typically feature carefully arranged stones, raked sand, and sometimes moss, to simulate the appearance of a flowing river or stream in a static, drought-resistant environment. These gardens are meant to evoke a sense of tranquility and simplicity, reflecting Zen Buddhist principles. Pictures of such gardens often showcase the artistic balance and minimalism that are characteristic of Japanese garden design.
