report on behalf of MITSuME collaboration:

We observed the field of GRB 140129A (Melandri et al., GCNC 15760)
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 2014-01-29 09:31:12 UT (~6.1 h after the burst).
We could not detect the previously reported afterglow (Melandri et al.,
GCNC 15760; Perley and Cenko, GCNC 15761) in all the three bands.

Three sigma upper limits of the OT are listed below.
We used GSC2.3 catalog for flux calibration.
