Daisugi, the 600-Year-Old Japanese Technique of Growing Perfectly Straight Trees Out of Other Trees

We’ve all admired the elegance of Japan’s traditional styles of architecture. Their development required the kind of dedicated craftsmanship that takes generations to cultivate — but also, more practically speaking, no small amount of wood. By the 15th century, Japan already faced a shortage of seedlings, as well as land on which to properly cultivate the trees in the first place. Necessity being the mother of invention, this led to the creation of an ingenious solution: daisugi, the growing of additional trees, in effect, out of existing trees — creating, in other words, a kind of giant bonsai.

“Written as 台杉 and literally meaning platform cedar, the technique resulted in a tree that resembled an open palm with multiple trees growing out if it, perfectly vertical,” writes Spoon and Tamago’s Johnny Waldman. “Done right, the technique can prevent deforestation and result in perfectly round and straight timber known as taruki, which are used in the roofs of Japanese teahouses.”
