  We consider a possibility to observe the axion emission from a nearby
supernova (SN) in the future, which can be known in advance by the pre-SN alert
system, by collider detectors like the LHC detectors (i.e., the ATLAS and the
CMS) and the ILC detectors (i.e., the ILD and SiD). The axion from the SN can
be converted to the photon by the strong magnetic field in the detector and the
photon can be detected by electromagnetic calorimeter. We estimate the numbers
of signal and background events due to a nearby SN and show that the number of
signal may be sizable. The axion emission from a nearby SN may be observed if,
at the time of the SN, the beam is stopped and the detector operation is
switched to the one for the SN axion search.
