This simulation system includes: a virtual space setting unit for subjecting a virtual space in which a plurality of objects are positioned to setting processing; a virtual camera control unit for subjecting a virtual camera corresponding to the viewpoint of a user wearing a head-mounted display device to control processing; and a display processing unit for generating an image visible from the virtual camera in the virtual space as a display image for the head-mounted display device. The virtual space setting unit positions at least one information display item, which is controlled so as to track the changes in the viewpoint of the user, in the virtual space. The display processing unit executes display state change processing for the information display item or the objects when a given positional relationship is formed between the information display item and the objects in the virtual space.
