PROBLEM TO BE SOLVED: To provide a movement route retrieval system, capable of retrieving an optimum movement route between two points having high frequency of movement and use by a user and accurately performing navigation of mobile terminals. SOLUTION: The movement route retrieval system, for retrieving a route for the terminal for moving between two points of start location and destination, comprises an information collection part 3a for collecting movement routes in which unspecific terminals have moved, the frequencies of use of the migration pathway by the same terminals, and identification information for identifying the terminals; a history information management part 3b for relating the information on the frequency of use of the movement routes by the terminals with the identification information collected by the information collecting part 3a and holding the information on the frequency of use as history information; and a retrieval part 3c for reading the history information from the history information management part 3b, on the basis of a retrieval command of movement routes and retrieving movement routes, on the basis of the terminal's frequency of use of movement routes to be retrieved.
