A display management device includes an acquisitioner and a data processor. The acquisitioner acquires occupancy request information from a first terminal. The occupancy request information indicates that a request is made to display content on a plurality of displays positioned in a first region. When the acquisitioner acquires the occupancy request information, the data processor generates a available time display data using a display information storage and transmits same to the first terminal. The display information storage stores information relating to available time of the plurality of displays positioned in the first region. The available time display data is data for displaying a screen which shows availability information including the number of displays which can be reserved and/or the occupancy rate thereof for each time period.
