The present invention is provided with: a user presence determination unit 24 which determines whether a virtual user corresponding to an actual user is present in a VR space; and an incentive granting unit 25 which, when the virtual user is determined to be present in the VR space, grants a prescribed incentive to the actual user, wherein, the incentive is caused to be granted to the actual user if the virtual user is only present in the VR space. Therefore, actively activating in the VR space or clearing a prescribed condition through activation is not a condition for being granted the incentive, and the user can relatively simply obtain the incentive.
