Rocks can be used in a variety of ways including, edging, paving, creating Tourou lanterns, Chozubachi, Rock arrangements, walls, Zen gardens, and ponds. The key difference between Western and Japanese gardening are rocks. The two sides have different approaches to the use of rocks but for Japanese gardens, it is the main element. It is the framework of the design.
