Futokoro

The Japanese word "Futokoro" means "bosom" or "pocket." In bonsai, it refers to the root parts of tree branches that are close to the tree trunk, which are valued in bonsai art.  Bonsai trees with branchy futokoro are considered more attractive and natural, as they show the connection between the trunk and the branches. The futokoro also helps to create depth and perspective in the bonsai design.
