A radiography system includes a mammography apparatus and a control device including a compression control unit that, in a case of performing continuous imaging in which the simple imaging and the tomosynthesis imaging are continuously performed while the breast being compressed by the mammography apparatus, performs control to cause a compression member to compress the breast at a first force in a first imaging of the simple imaging or the tomosynthesis imaging that is performed first in the continuous imaging, to change a force of the compression member compressing the breast from the first force to a second force lower than the first force after the first imaging, and to cause the compression member to compress the breast at the second force in a second imaging that is performed later.
