A radiography system for executing long-length imaging by using a plurality of radiation imaging apparatuses includes an acquisition unit configured to acquire respective states of the plurality of radiation imaging apparatuses, and a state control unit configured to shift power consumption of one radiation imaging apparatus to a same state as that of another radiation imaging apparatus based on the respective states acquired by the acquisition unit in a case where at least the one radiation imaging apparatus from among the plurality of radiation imaging apparatuses is in a state where the power consumption is higher than that of the another radiation imaging apparatus.
