Properties of PEARSON's type VII distribution were examined by applying this distribution to data on the frequency distribution of individual weight in Cryptomeria japonica and Larix leptolepis stands. These stands satisfied the TADAKI's model of natural thinning. Limited by the TADAKI's model, all the coefficients of the distribution density function of individual weight were formulated by empirical equations of the population density of trees. These empirical equations leaded a mathematical model for describing the frequency distribution of individual tree weight in forest stands restricted by the TADAKI's model of natural thinning. This model of the frequency distribution of weight depended on a normalized distribution density function of tree weight and was specific to every set of the coefficient values of TADAKI's model.
