report on behalf of the MITSuME and OISTER collaboration:

We observed the field of GRB 151029A (Ukwatta et al., GCNC 18522)
with the optical three color (g', Rc and Ic) CCD camera attached
to the Murikabushi 1m telescope of Ishigakijima Astronomical
Observatory.

The observation started on  2015-10-29 14:56:55 UT (~6.5h after
the burst). We could not detect the previously reported afterglow
(Ukwatta et al., GCNC 18522; Knust et al., GCNC 18523;
Tanvir et al., GCNC 18524) in all the three bands.

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