report on behalf of MITSuME and OISTER collaboration:

We observed the field of GRB 130511A (Krimm et al., GCNC 14620)
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 2013-05-11 12:01:00 UT (~30 min after the burst).
We did not find any new point source within the enhanced XRT error circle
(Osborne et al., GCNC 14622) in all the three bands.

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