The first written guide on Japanese landscaping, the Sakuteiki, describes creating gardens as: Ishi wo taten koto (石を立てん事). This translates to setting stones upright, a description that greatly emphasizes the importance of these elements within the Japanese garden.

Traditionally applying ornamental rocks, Niwaishi (庭石) in Japanese, forms the basis of practically every Japanese garden. The setting of stones is always the first step, after which the garden is formed together with all the other elements surrounding it.

An authentic Japanese garden needs to evoke a certain natural essence. Rocks and stones play a significant role regarding this principle as they are pure elements, taken straight from nature.

Ibigawa is an authentic Japanese rock type that originates from the famous Ibigawa river, which flows through Gifu and Mie prefecture. The stones are often seen in the Japanese garden but are also particularly well-known in the world of Bonsai for their application in the Sekijoju style. Bonsai with roots growing over rocks.
