I examined the relations with branches and foliage of a Hinoki-tree. The diameter of a branch “b” was about 1% of its length “B”. Then I named “Bb” Extent-of-Branch. The weight of foliage of a branch “c” was in proportion to its Bb, the relation was Bb/c=2(cm2/g). And the distance between a branch and the top of the stem “l” was in proportion to the length of the branch of a branch group, the relation was B/l=15-60(cm/m). There was the upper limit of B. In the distance from the limit, the weight of foliage of branches per Δl was in proportion to l. Therefore the crown shape was supposed to be a cone. As a result, the weight of foliage of branches limited branches’ length and diameter. Furthermore the stem shape without its upper part was described with the other parameters. Finally I got a shape model for Hinoki trees.
