A location determination system includes a vehicle device (10) mounted in a vehicle, and a mobile terminal (20) which is a communication terminal to be carried by a user of the vehicle and set to transmit a radio signal including transmission source information at least once within a predetermined period of time. The vehicle device includes a reception portion (140, 150, or 160) which receives the radio signal transmitted from the mobile terminal via an antenna disposed in the vehicle and detects a reception strength of the received radio signal, and a location determination portion (F6) which determines, based on the reception strength of the radio signal detected by the reception portion, whether the mobile terminal is present inside a target area set in advance based on a position at which the antenna is disposed.
