Sanbaseki Stone, 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.

Sanbaseki stones come in various types, sizes, and colors such as white, red, brown, yellow, green, and blue. The stone type can be recognized by the multiple layers and often white streaks on the surface. The name Sanbaseki comes from the Sanba River in Gunma Prefecture where the stone type originally originates from.
