report on behalf of the MITSuME collaboration:
We observed the field of GRB 141212B (M. Stamatikos et al., GCN Circular #17159) 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 19:31:43 UT (~6 h after the burst).
We did not find any new point source within the enhanced XRT circle
(K. L. Page et al., GCN Circular #17174) in all the three bands.
The measured magnitudes are listed below.
