A radiographic imaging system, a radiographic imaging method, and a storage medium are capable of avoiding the collision of the operations, even if the operations based on a plurality of terminal apparatuses occur. The radiographic imaging system includes a radiographic imaging apparatus configured to generate a radiographic image based on radiation emitted from a radiation generating apparatus, and a control unit configured to control the radiographic imaging apparatus based on instructions from a first terminal apparatus and a second terminal apparatus. The second terminal apparatus acquires a right to control the control unit from the first terminal apparatus, and the control unit controls the radiographic imaging apparatus based on an instruction from the second terminal apparatus.
