A processor 180 of a navigation device 100 acquires current position information about a current position of a vehicle. The processor 180 then generates current traffic-jam information about a current traffic-jam condition based on VICS data from a VICS receiver 120 or the like. The processor 180 recognizes a direction indicating a point at which a traffic jam is currently occurring relative to the current position based on current position information and current traffic-jam information. The processor 180 displays the recognized direction with a traffic-jam direction icon on a terminal display section 140.
