Japanese Zen rock garden design

Quick answer：

Japanese Zen rock gardens, also known as 'karesansui,' are minimalist landscapes that incorporate carefully placed stones, raked sand, and sometimes moss to represent a natural landscape. The design aims to evoke a sense of tranquility and the natural beauty of mountains and water. It is deeply rooted in Zen Buddhism and reflects the concept of wabi-sabi, which values simplicity, imperfection, and the fleeting nature of beauty.
