report on behalf of the MITSuME collaboration:

We observed the field of GRB 110414A (Starling et al., GCN 11931)
with the optical three color (g', Rc and Ic) CCD camera attached
to the MITSuME 50cm telescope of Okayama Astrophysical Observatory.

The observation started on 2011-04-14 10:35:42 UT (~2.9 h after
the burst). We did not find any new point source within the
Enhanced XRT circle (Osborne et al., GCN 11934) in all the three
bands.

Three sigma upper limits of the OT are listed below. We used
GSC2.3 catalog for flux calibration.
