report on behalf of the MITSuME and OISTER collaboration:

We observed the field of GRB 140705A (Stamatikos et al., GCNC 16520)
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 2014-07-05 13:08:26 UT (~3.6 h after the burst).
We did not find any new point source within the enhanced XRT circle
(Osborne et al., GCNC 16521) in all the three bands.

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