report on behalf of MITSuME and OISTER collaboration:

We observed the field of GRB 161108A (Beardmore et al., GCNC 20145)
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 2016-11-08 17:48:36 UT (~14.3 h after
the burst). We could not detect the previously reported afterglow
(Malesani et al., GCNC 20146; Butler et al., GCNC 20149)
in all the three bands.


Three sigma upper limits of the OT are listed below.
We used SDSS-DR8 catalog for flux calibration.
