Sagan Sandstone, Japanese Garden Rock

The first manual for the Japanese garden, the Sakuteiki, describes the laying out of gardens as: Ishi wo taten koto (石を立てん事). This means the upright placement of stones, which strongly emphasizes the important role of these elements within the Japanese garden.

The correct application of garden stones, Niwaishi (garden stones) in Japanese, forms the basis of practically every Japanese garden. The placement of stones and rocks is almost always determined first, after which the garden is formed together with all the elements surrounding it. Because of this, stones and rocks are also known as the Kikotsu (気骨), or backbone, of the Japanese garden.

An authentic Japanese garden should mimic a certain natural essence. Stones and rocks are a significant part of this principle since they concern pure elements, coming directly from nature.

Since Japan is an island, there are many coastal areas resulting in a significant amount of sandstone, according to Sagan in Japanese. A traditional principle of the Japanese garden is that elements must be incorporated directly from nature. This is something that this kind of Japanese sandstone is very well suited for.
