The Japanese word "eda" means branch. There are different types of branches that have specific names and functions in bonsai design, such as sachi eda, uke eda, kiki eda, and kuitsuki eda. Sachi eda is the most dominant branch that defines the flow and direction of the tree. Uke eda is the second most dominant branch that acts as a counterpoint or balance to the sachi eda. Kiki eda is a branch that has a strong effect on the overall impression of the tree. Kuitsuki eda is a branch that is smaller than the main branch and grows from its base.
