1. A navigation device which is provided with a route guider that generates route information on the basis of position information of a host vehicle and map data, to thereby perform route guidance for a user who drives the host vehicle, the route information indicating the host vehicle's route, comprising: a route identifier that extracts a turning position of the host vehicle on the basis of the route information acquired from the route guider, to thereby prepare, as a recognition region, a predetermined range of the host vehicle's route after the turning position; a vehicle recognizer that acquires the recognition region from the route identifier to thereby detect within the recognition region, one or more nearby vehicles with respect to the host vehicle on the basis of an image captured ahead of the host vehicle in traveling, and that informs of a vehicle trajectory and a vehicle image of the one or more nearby vehicles, as a recognition result, the route identifier determining a preceding vehicle from the one or more nearby vehicles traveling on the route that is the same as that of the host vehicle, on the basis of the recognition result acquired from the vehicle recognizer; and a guide information generator that generates preceding vehicle information for providing to the user a presentation of the preceding vehicle determined by the route identifier, wherein the route guider, at the time of performing the route guidance, provides the presentation of the preceding vehicle to the user by a predetermined presentation method, on the basis of the preceding vehicle information generated by the guide information generator.
