Kawai(Tokyo Tech) report on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 110112A (Stamatikos et al.,GCN 11553)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the MITSuME 50cm telescope of Akeno Observatory and Okayama\nAstrophysical Observatory.\n\nWe did not find any new point source within the enhanced XRT error\ncircle (Evans et al., GCN 11556) in all the three bands. We could\nnot detect the previously reported afterglow (Xin et al., GCN 11554).\n\nThree sigma upper limits of the OT are listed below. We used GSC2.3\ncatalog for flux calibration.\n\nAkeno Observatory:\nThe observation started on 2011-01-12 09:07:48 UT (~5 h after the\ntrigger).\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.21513    09:22:06    1200.0   >20.2  >20.0  >19.4\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]\n\nOkayama Astrophysical Observatory:\nThe observation started on 2011-01-12 09:15:35 UT (~5.1 h after\nthe trigger).\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.23603    09:52:11    3840.0   >19.9  >19.8  >19.3\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
