Japanese Zen garden miniatures, known as 'zen rock gardens' or 'kare-sansui,' are miniature landscapes designed to evoke a sense of tranquility and the beauty of nature. They typically feature white sand or pebbles to represent water, and carefully placed rocks to symbolize mountains and islands. The design aims to embody the principles of wabi-sabi, which emphasizes simplicity, naturalness, and the acceptance of transience.
