PROBLEM TO BE SOLVED: To provide a retrieval technology for intuitively displaying the retrieval result of data having the location information of a designated region and time information within a designated period. SOLUTION: When an information retrieval terminal transmits retrieval conditions including location information and time information to a server, the server retrieves data including location information showing locations included in a region to be determined on the basis of the location information in the retrieval conditions and time information showing a time to be determined on the basis of the time information in the retrieval conditions or a time within the period as attribute information from among data stored by the server, and acquires map image data of the region from among map image data stored in a storage device in advance, and transmits the retrieve data and the location information of the retrieved data and the acquired map image data to the information retrieval terminal. The information retrieval terminal displays the acquired map image data, and displays the retrieved data at a position corresponding to the position information of the retrieved data on the displayed map image data.
