A real-life scene of a dry landscape garden in a Zen rock garden

Quick answer：

Zen rock gardens, also known as 'kare-sansui' in Japanese, are a traditional form of Japanese garden design that emphasizes the use of stone arrangements to represent natural landscapes. These gardens often feature elements such as pebbles, rocks, and sometimes moss, arranged to convey the essence of mountains, rivers, and oceans. They are designed to be tranquil and meditative, inviting contemplation of the natural world.
