report on behalf of MITSuME collaboration:

We observed the field of GRB 140502A (Swenson et al., GCNC 16202)
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 2014-05-02 16:48:47 UT (~8.3 h after the burst).
We did not find any new point source within the enhanced XRT circle
(Goad et al., GCNC 16206) in all the three bands.

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