The present landmark update system enables route guidance through the use of landmark information which remains always the latest for route guidance, and operates as follows: a navigation device1communicates with a landmark server30so as to receive to-be-updated landmark information1001for guiding the user by utilizing landmarks. Information about any landmark displayed is transferred to the landmark server30as cumulative information1002. The landmark server30manages the cumulative information1002so that compilation data1003is generated for transfer to a retailer terminal40corresponding to the displayed landmark(s). The retailer terminal40refers to the compilation data1003so as to generate landmark information which is considered optimum, and transfers it to the landmark server30as registering landmark information1004.
