Mikihada is a Japanese term that means trunk surface or bark of a tree. It is an important aspect of bonsai appreciation, as it reflects the age and quality of the tree. The mikihada of a bonsai tree can vary depending on the species, the environment, and the care given by the bonsai artist. Some bonsai trees have smooth and thin bark, while others have rough and thick bark. Some bonsai trees develop cracks, fissures, or flakes on their bark, which can add character and interest to the tree. The mikihada of a bonsai tree can also change color over time, becoming darker or lighter.
In relation to bonsai, mikihada is one of the factors that determine the style and shape of the tree. For example, a bonsai tree with a curved and twisted trunk may have a more dynamic mikihada than a straight and upright trunk. A bonsai tree with a thick and rough bark may have a more masculine appearance than a thin and smooth bark. A bonsai tree with a colorful and textured bark may have a more attractive appearance than a dull and plain bark.
