Submerged Japanese landscape refers to a type of garden design that involves creating a scene of natural beauty beneath the water's surface. This style is rooted in traditional Japanese aesthetics and often includes elements such as rock formations, plants, and sometimes even small architectural features like stepping stones or small bridges. The concept is to create a tranquil, serene atmosphere, reminiscent of natural underwater landscapes. This particular style of garden design is particularly popular in Japanese Zen gardens and can be found in both indoor and outdoor settings.
