• Modelling for this study was based on branch data from a sample of hinoki (Chamaecyparis obtusa) stands of different ages, silvicultural histories and varieties. Calculations of the relative crown curve of the exposed part of the crown were then made, based on branch tip position. We then investigated differences in relative exposed crown form due to tree age, silvicultural treatment and variety. It was concluded that the changes in crown length, diameter and slenderness ratio in the growing stages for Hinoki show similar tendencies to sugi (Cryptomeria japonica). It was confirmed that the difference of due to stand age, silviculture and variety. There are significant differences in the relative exposed crown form. The relative crown curve was calculated from a regression equation based on branch data for all the sample trees.
