report on behalf of MITSuME and OISTER collaboration:

We observed the field of GRB 141015A (Troja et al., GCNC 16909)
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 2014-10-15 13:44:05 UT, (~4.5 h after the burst).
We did not find any new point source within the enhanced XRT circle
(Evans, GCNC 16913) in all the three bands.

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