The presence display system of the present invention displays presences and distances between buddies.The mobile station 11 performs poling to the user data section 26 at predetermined time intervals, transmits location information of the mobile station 11 to the presence server 27, receives buddies state information and information indicating the proximity between the user and the buddies, and displays the presence of the buddies by means of an icon with a size that corresponds with the proximity. The buddy list server 28 calculates the distance between the user and the buddies from the location information of the mobile station 11 and the location information of the requested buddies in accordance with the poling by the mobile station 11, determines the proximity by comparing the distance with a threshold value that is set by the user, and transmits the proximity to the mobile station 11.
