report on behalf of the MITSuME collaboration:

We searched for the optical counterpart of GRB 160410A (S. L. Gibson et al., GCN Circular #19271) with the 
optical three color (g', Rc, and Ic) CCD cameras attached to the MITSuME 50 cm
telescope of Akeno Observatory, Yamanashi, Japan.

The observation started on 2016-04-10 12:06:25 UT (~7.1 h 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+[hour]    MID-UT     T-EXP[sec]      g'         Rc          Ic

We used GSC2.3 catalog for flux calibration.
