report on behalf of the MITSuME collaboration:
We searched for the optical counterpart of GRB 160104A (A. Melandri et al., GCN
Circular #18815) 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 2016-01-04 11:24:56 UT (46 sec after the burst) and
we detected the optical counterpart in Rc and Ic band.
The measured magnitudes were listed as follows.
We obtained following limits for the magnitudes.
T0+[sec] MID-UT T-EXP[sec] g' Rc Ic
