A movement sound generation system (1) generates a movement sound when a moving body moves on a predetermined movement surface in a virtual space. A sound volume of the movement sound is decided based on a mass of the moving body in the virtual space. A sound quality of the movement sound is decided based on material information of a ground contacting portion of the moving body which contacts a movement surface in the virtual space, and on material information of the movement surface contacted by the ground contacting portion of the moving body. A sound production timing of the movement sound is decided based on a timing at which the ground contacting portion of the moving body contacts the movement surface. The movement sound of the moving body is played in the virtual space, with a sound volume, with a sound quality, and at a sound production timing.
