A unique forestry technique, which kinda looks like a small forest growing on a tree. forest Daisugi involves carefully pruning and nurturing cedar trees to encourage the growth of straight, tall, and branchless trunks. These trees are then harvested without cutting them down entirely, allowing new shoots to grow from the same stump. Daisugi has been practiced for centuries and is known for producing high-quality, knot-free wood used in traditional Japanese construction, such as tea houses and shrines.
