Japanese Zen rock garden

Quick answer：

A Japanese Zen rock garden, also known as a karesansui, is a minimalist landscape garden that uses stones, sand, and occasionally moss arranged in a particular pattern to represent natural landscapes such as mountains, waterfalls, and rivers. The concept aims to evoke a sense of tranquility and the beauty of nature. These gardens are typically found in Japanese Zen Buddhist temples and are designed to be contemplative spaces.
