A landing management device sets a partition, in a predetermined landing area, on the basis of information of an unmanned aerial vehicle that lands on a landing area, the partition being obtained by virtually partitioning a part of the landing area, and transmits landing control information to a control device, in order to make the unmanned aerial vehicle land on a partial area corresponding to the partition. The control device controls landing of the unmanned aerial vehicle on the basis of the landing control information received from the landing management device.
