The Kikieda, or "focal point" of a bonsai tree, is the area where the trunk and the main branches form a harmonious curve. The Kikieda is considered the most important feature of a bonsai, as it reflects the natural beauty and balance of the tree. The Kikieda should be clearly visible from the front view of the bonsai, and should not be obscured by foliage or other elements. The Kikieda should also be proportional to the size and shape of the bonsai, and should not be too thick or thin. A well-defined Kikieda can enhance the aesthetic appeal and artistic expression of a bonsai.
