Japanese Zen Temple Rock Garden

Quick answer：

Japanese Zen rock gardens, known as 'kare-sansui,' are dry landscape gardens that use carefully arranged rocks, sand, and gravel to represent a natural landscape, typically a mountainous terrain or a sea shore. These gardens are a form of Japanese Zen Buddhism art, symbolizing the natural world in a minimalist style. They are often found in Zen temples and are intended to evoke a sense of tranquility and introspection.
