Disclosed is a radiation image capturing system. The radiation image capturing system includes a radiation image capturing apparatus and a capturing control apparatus. The radiation image capturing apparatus detects irradiating timing of radiation. The capturing control apparatus is able to communicate data to control the radiation image capturing apparatus. The capturing control apparatus includes, a storage section which stores capturing order information corresponded with a detecting condition of irradiating timing of radiation an obtaining section which obtains capturing order information and a first control section which reads the detecting condition corresponded to the obtained capturing order information and which transmits the read detecting condition to the radiation image capturing apparatus. The radiation image capturing apparatus includes a second control section which detects the irradiating timing based on the detecting condition.
