In an effort to develop a model for accurately predicting foliage area (FA) of a branch of Cryptomeria japonica, we analyzed the relationship between FA and the basal area inner bark of the branch (P_0BA), and between FA and the cross-sectional area inner bark of the branch measured at the farthest point from the tip of the branch to which foliage shoots were still attached (P_1BA). The FA-P_1BA relationship had a higher correlation than the FA-P_0BA relationship, and showed no difference among trees. The FA-P_1BA relationship was expressed as FA = 0.627 P_1BA. The constant relationship of FA-P_1BA offers a convenient means of estimating the FA in C. japonica.
