One of the main purposes of the IRIS mission is an all-sky survey in the far-infrared region with a flux limit much deeper than that of IRAS. Detection of a large number of galaxies ($\\sim several \\times 10^6$ in the whole sky) is expected in this survey. We investigated the expected optical and near-infrared (NIR) number counts of galaxies detected by the far-infrared scanner (FIS) of IRIS (hereafter, IRIS galaxies) and possibility of optical and NIR follow-up of them.
