The navigation apparatus includes a map-drawing unit that draws the map of an area from map data on shapes and positions of the building symbols at a selected map scale, and a displaying unit that displays the drawn map. In the navigation apparatus in a nighttime-map displaying mode, the map-drawing unit draws the entirety of each building symbol in a bright color to generate the map when the map scale exceeds a predetermined threshold, or draws part of the building symbol in a bright color to generate the map when the map scale does not exceed the predetermined threshold.",
