report on behalf of the MITSuME collaboration:
We observed the field of GRB 141212A (T. N. Ukwatta et al. GCN Circular #17158) 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 2014-12-12 12:14:32 UT (31 sec after the burst).
We did not find any new point source within XRT circle in all three bands.
The measured magnitudes are listed below.
