PROBLEM TO BE SOLVED: To retrieve sightseeing information suitable for the present location of a user and provide the same to the user.SOLUTION: A user portable terminal 20 includes a camera 44, a GPS receiver 48 for measuring the present location of a user, an azimuth angle sensor 49 for measuring an azimuth angle of the present visual line of the user, and a memory 42 which stores a plurality of reference areas assigned to a plurality of objects on a map and a plurality of pieces of sightseeing information in association with each other, and a retrieval module. Among the plurality of pieces of sightseeing information, the information associated with each reference area includes a plurality of pieces of information for each azimuth angle. The retrieval module extracts a reference area in which the measured present user location is located from the plurality of reference areas, and extracts the information corresponding to the measured present user azimuth angle from the plurality of sightseeing information for each azimuth angle associated with the extracted reference areas, and provides the extracted sightseeing information for each azimuth angle to the user.
