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.

Hirukawa is an authentic Japanese granite type that originates from the town of Hirukawa, which is part of Nakatsugawa city in Gifu prefecture since 2005. Hirukawa granite is used very often in the Japanese garden for elements such as stone lanterns, Chōzubachi and bridges. But individual Hirukawa stones can also be beautifully applied as ornamental rocks.
