To provide a "navigation system" that guides a passing direction of an intersection while suppressing misunderstanding of a road to be traveled.SOLUTION: In a case that a road 502 to get out of a guidance target intersection 510 being viewed from a road 501 to enter the guidance target intersection 510 is located in an oblique right direction, and voice data of a voice "go in an oblique right direction at 300 m ahead" is defined as the voice data to guide an intersection passing direction, when there is other road 503 which has lanes being more than or equal to four lanes and which connects to the guidance target intersection 510 through between the road 501 and the road 502, guidance of the intersection passing direction is performed by means of the voice of "go in an oblique right direction at 300 m ahead, at an opposite side of an intersection" obtained by adding "at an opposite side of an intersection" to the voice of the voice data.SELECTED DRAWING: Figure 6
