Chokkan (Formal Upright)
This traditional bonsai style is very common in bonsai. The tree grows in a straight upward line with the crown of the tree directly above the base of the trunk. The tree clearly shows the tapering of the trunk. The branches start at a quarter of the height of the three, and the length of first branch should be a third of the height of the entire tree. Branches are distributed symmetrically across the trunk and the top of the tree is formed by a branch, not by the trunk itself.
This style mimics the growth of trees in nature that receive a lot of sunlight and don’t have to compete with other trees for their position.
