Kawai(Tokyo Tech) report on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 101219A (Gelbord et al., GCN 11461)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the Murikabushi 1m telescope of Ishigakijima Astronomical\nObservatory.\n\nThe observation started on 2010-12-19 10:30:50 UT (~8.0 h after\nthe trigger). We did not find any new point source within the XRT\nerror circle (Gelbord et al., GCN 11461) in all the three bands.\n\nThree sigma upper limits of the OT are listed below. We used SDSS\ncatalog for flux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.33651    10:36:04     480.0    >19.1  >19.1  >18.7\n0.46387    13:39:28    1500.0    >20.9  >20.7  >20.0\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
