Atama (頭) is a Japanese word that means head. It is often used to refer to the head or the crown of a bonsai tree, which is the uppermost part of the foliage. The atama is important for creating a balanced and harmonious appearance of the bonsai, as well as for expressing the age and character of the tree. It should be proportional to the trunk and the branches, and it should have a clear outline and a dense foliage. The atama can be styled in different ways depending on the type and the age of the bonsai tree.
