A Japanese Zen rock garden, also known as a 'kare-sansui,' is a traditional Japanese garden that emphasizes the essence of nature through minimalist landscaping. It often includes carefully arranged rocks, sand, and sometimes gravel, representing mountains, water, and the sky. These gardens are designed to evoke a sense of tranquility and contemplation. In an office setting, a Zen rock garden can serve as a stress-relieving and meditative space, fostering a peaceful atmosphere.
