The purpose of the present invention is to accurately land a vertical takeoff/landing aircraft on a target landing point. This automatic landing system is provided with: an imaging device mounted on a vertical takeoff/landing aircraft; a relative-position acquiring unit that performs image processing on an image, of a marker provided to a landing target point, captured by the imaging device, and that acquires a relative position between the vertical takeoff/landing aircraft and the landing target point; a relative-altitude acquiring unit for acquiring a relative altitude between the vertical takeoff/landing aircraft and the landing target point; and a control unit for controlling the vertical takeoff/landing aircraft in a plurality of control modes so that the relative position becomes zero, wherein the control modes include a hovering mode and a landing mode. In the hovering mode, the relative altitude of the vertical takeoff/landing aircraft is lowered to a predetermined relative altitude when the relative position is within a first threshold value. The transition to the landing mode takes place upon satisfaction of predetermined conditions including a condition in which the relative position is within a predetermined threshold value which is less than the first threshold value. In the landing mode, the relative altitude of the vertical takeoff/landing aircraft is further lowered so as to make a landing on the landing target point.
