report on behalf of the MITSuME collaboration:
We searched for the optical counterpart of GRB 160601A (D. Kocevski et al., GCN Circular #19478)
with theoptical three color (g', Rc, and Ic) CCD cameras attached to the
MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan.
The observation started on 2016-06-01 23:43:35 UT (33 sec after the burst).
We did not find any new point source within XRT circle in all three bands.
We obtained following limits for the magnitudes.
T0+[day] MID-UT T-EXP[sec] g' Rc Ic

0.078 16:35:35 12060 >21.7 >21.1 >19.9
------------------------------------------------------------------------------------------
T0+ : Elapsed time after the burst.
T-EXP: Total Exposure time.
We used GSC2.3 catalog for flux calibration.
