report on behalf of MITSuME and OISTER collaboration:

We observed the field of GRB 160601A (Kocevski et al., GCNC 19478)
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 2016-06-01 14:43:48 UT (~46 sec after
the burst). We did not find any new point source within the XRT
circle (Kocevski et al., GCNC 19478) in all the three bands.

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