PROBLEM TO BE SOLVED: To provide a hair simulation method capable providing an animation image rich in reality, and capable of shortening extremely a processing time in simulation. SOLUTION: This hair simulation method is provided with a hair master simulation step of constituting a hair bundle of hair members distributed in the periphery of one hair master, using a particle model as a model of each of the hair masters and hair members, including a hair master initialization step and a hair member initialization step, and for calculating positions of all the master particles constituting the hair master, and a hair member deformation step for changing relative coordinates among the respective member particles constituting the respective hair members, based on motion speed vectors of the master particles, and is provided further a hair member generation step for calculating a position of each member particle in each hair member, based on the positions of the master particles calculated in the hair master simulation step and based on a relative position of the member particle changed in the hair member deformation step.
