A vehicle occupant information acquisition system including an onboard device mounted to a vehicle and at least one vehicular portable device associated with the onboard device is provided. The vehicular portable device has a function of performing short-range communication with portable terminals, determines a holder's terminal based on a variation in received signal strength indication of a signal sent from each portable terminal, and sends a holder information signal identifying the holder's terminal to the onboard device. The onboard device identifies a user holding the vehicular portable device based on the holder information signal sent from the vehicular portable device, and identifies a portable device location by receiving a response signal. A seat determined based on the portable device location is determined to be a seated location of the user acting as the portable device holder.
