report on behalf of the MITSuME collaboration:
We observed the field of GRB 160101A (D.Itoh et al., GCN Circular #18793) 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 2016-01-01 18:33:56 UT (~17.8 h after the burst). We cound not detect any optical point source in the error circle of the previously reported afterglow detected by Swift-XRT (L.Izzo et al., GCN Circular #18795) in all three bands.
Three sigma upper limits are listed below.
