A wake-up system, comprises an illumination apparatus 2 which irradiated wake-up light L1, a control apparatus 3 which controls output of the wake-up light L1 irradiated from the illumination apparatus 2, and an interface apparatus 4 which is operated by a user to input at least a wake-up time, the illumination apparatus 2 comprises an output variation apparatus 24 which varies output of the wake-up light to be irradiated, and a color temperature variation apparatus 24 which varies color temperature of the wake-up light L1, and the control apparatus 3 comprises a light output control unit 31 which controls the output variation apparatus 24 so as to increase the output of the wake-up light L1 irradiated from the illumination apparatus 2 from an wake-up operation start time to the wake-up time, and a color temperature control unit 31 which controls the color temperature variation apparatus 24 such that color temperature of the wake-up light L1 in a time period from a first time to the wake-up time, the first time is a time passing a first predetermined time period from the wake-up operation start time becomes higher than color temperature of the wake-up light L1 in a time period from a second time to the first time, the second time is a time before a second predetermined time period shorter than the first predetermined time period from the first time.
