Daisugi the Japanese Technique of Trees Out of Trees, Making Exact Straight Wood

Daisugi is a 600-year-old Japanese forestry technique that grows multiple trees from a single parent tree, similar to giant bonsai, producing perfectly straight and strong timber used in traditional architecture. Developed in 15th-century Kyoto to address timber shortages, the method creates lumber that is 140% more flexible and 200% denser than standard cedar, making it ideal for roofs and rafters of Japanese teahouses. The technique remains admired worldwide today for its sustainability and engineering elegance.
