Japanese Zen Garden with Rock Work

Quick answer：

Japanese Zen gardens, also known as rock gardens or karesansui, are traditional Japanese gardens that use stones, moss, and sand to represent landscapes. They are characterized by their minimalist design, simplicity, and the use of natural elements to evoke a sense of calm and contemplation. The term 'karasu-sansui' literally means 'scattered stones' and refers to the arrangement of rocks to create a natural-looking landscape, typically representing mountains, rivers, and sea. These gardens are a significant part of Japanese culture and philosophy.
