A wireless communication system includes a plurality of wireless terminals. Each of transmitting terminals executes direct communication or indirect communication. The wireless communication system includes a first obtainer that obtains a reception side terminal number which is the number of the wireless terminals with which the receiving terminal is able to communicate directly, a second obtainer that obtains a transmission side terminal number which is the number of the wireless terminals with which the transmitting terminal is able to communicate directly for each of a target transmitting terminal and a neighboring transmitting terminal, and a setter that selects one of the direct communication and the indirect communication based on the reception side terminal number, the transmission side terminal number for the target transmitting terminal, and the transmission side terminal number for the neighboring transmitting terminal, and executes the selected communication.
