Japanese-style rock garden landscape ornaments

Quick answer：

Japanese-style rock garden landscape ornaments, known as 'kare-sansui' in Japanese, are small-scale, abstract landscapes composed primarily of rocks, sand, and sometimes moss. These miniature gardens are designed to evoke the natural beauty of mountains, rivers, and other natural elements, and are a significant aspect of Japanese garden design and Zen Buddhism. They often feature carefully arranged rocks to represent islands or mountains, with raked sand representing water. This practice of gardening, which emphasizes the beauty of simplicity and the harmony with nature, has influenced gardens around the world.
