Japanese Zen rock garden landscape

Quick answer：

Japanese Zen rock gardens, known as 'kare-sansui,' are a traditional form of Japanese garden design that emphasizes simplicity and the natural elements of rocks, sand, and moss. These gardens are designed to evoke a sense of tranquility and the beauty of nature, often incorporating elements such as stepping stones and carefully arranged rocks to represent mountains and water. The concept originates from Buddhist teachings and Zen philosophy, aiming to create a peaceful retreat that reflects the mind's journey towards enlightenment.
