report on behalf of MITSuME and OISTER collaboration:
We observed the field of GRB 151229A (Kocevski et al., GCNC 18745)
with the optical three color (g', Rc and Ic) CCD camera attached
to the MITSuME 50cm telescope of Okayama Astrophysical Observatory.
The observation started on 2015-12-29 09:07:26 UT (~2.3h after the burst).
We did not find any new point source within the enhanced XRT circle
(Osborne et al., GCNC 18750) in all the three bands.
Three sigma upper limits of the OT are listed below.
We used GSC2.3 catalog for flux calibration.
