In an information acquisition system such as a car navigation system, a history accumulation DB 104 accumulates user's travel history. A condition determination section 107 determines a condition for retrieval for performing accurate prediction, and a prediction section 108 predicts a travel destination using the condition for retrieval. An information-to-be-presented determination section 110 acquires information relating to the travel destination predicted by the prediction section 108 from a received information DB 802 or the like.
