A device for generating intersection guidance information, which includes: a route setting unit configured to receive a route up to a destination; a candidate area detecting unit configured to search for a turning point on the searched route, and detect a surrounding area of the searched turning point as a candidate area; a candidate POI area detecting unit configured to detect a POI area as a candidate POI area, at least a portion of the POI area being included in the candidate area; a guidance POI area selecting unit configured to calculate distance between the candidate POI area and the turning point, search a candidate POI area whose distance calculated is shortest, and select the searched candidate POI area as a guidance POI area.
