Kawai(Tokyo Tech) report on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 100305A (Troja et al. GCNC 10470)\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 2010-03-05 13:03:55 UT (~4h after the\nburst). We did not find any new point source in the XRT error\ncircle (Osborne et al., GCNC 10474) in all the three bands.\n\nThree sigma upper limits of the OT are listed below. We used\nSDSS catalog for flux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.18816    13:36:35  3300.0      >22.1  >21.6  >20.4\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
