Kawai (Tokyo Tech) report on behalf\nof the MITSuME collaboration:\n\nWe observed the field of GRB 081222 (Grupe et al. GCN 8691) with\nthe optical three color (g', Rc and Ic) imager attached to the\nMITSuME 50cm telescope of Okayama Astrophysical Observatory on\nDec.22 2008 UT. We detected a fading point source at the position\nof the X-ray - optical afterglow candidate (Covino et al. GCN 8692;\nUpdike et al. GCN8693; Grupe GCN 8705) in Rc band. Photometric\nresults are listed below. We used GSC2.3 catalog for flux\ncalibration.\n\n# Mid-MJD      Mid-UT   EXP-T    g'       Rc          Ic\n-------------------------------------------------------------\n54822.401100  09:37:36  540.0  >18.3  18.0+/-0.3  >17.8\n54822.438455  10:31:23 2940.0  >19.2  18.9+/-0.3  >18.2\n54822.469650  11:16:18 4500.0  >19.2  19.3+/-0.4  18.6+/-0.3\n-------------------------------------------------------------",
