report on behalf of the MITSuME collaboration:
We searched for the optical counterpart of GRB 160127A (A. Amaral-Rogers et al., GCN Circular #18938) 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 2016-01-27 17:04:39 UT (~8.4 h after the burst).
We did not find previously reported afterglow (A. Amaral-Rogers et al., GCN Circular #18938;
A. Klotz et al., GCN Circular #18939; A. Cucchiara et al., GCN Circular #18941) in all three bands.
We obtained following limits for the magnitudes.
