report on behalf of the MITSuME collaboration:

We observed the field of GRB 130505A (Cannizzo et al., GCNC 14563)
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 2013-05-05 10:52:56 UT (~2.5 h after the burst).
We detected the previously reported afterglow (Cannizzo et al., GCNC 14563)
in all the three bands.

Photometric results of the OT are listed below.
We used SDSS catalog for flux calibration.
