report on behalf of MITSuME and OISTER collaboration:

We observed the field of GRB 150302A (Lien et al., GCNC 17526)
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 2015-03-02 11:23:12 UT (~5.7 h after the burst).
We could not detect the previously reported afterglow (Fynbo et al., GCNC 17527)
in all the three bands.

Three sigma upper limits of the OT are listed below.
We used SDSS-DR8 catalog for flux calibration.
