report on behalf of MITSuME collaboration:

We observed the field of GRB 140114A (Troja et al., GCNC 15728)
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 2014-01-14 14:12:05 UT (~2.2 h after the burst).
We could not detect the previously reported afterglow (Butler et al., GCNC
15732) in all the three bands.

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