report on behalf of the MITSuME and OISTER collaboration:

We observed the field of GRB 140629A (Lien et al., GCNC 16477)
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 2014-06-29 14:20:40 UT (~3.2 min after the burst).
We detected the previously reported afterglow (Yurkov et al., GCNC 16478;
Xin et al., GCNC 16480; Bikmaev et al., GCNC 16482; Masi, GCNC 16483;
Maehara, GCNC 16484) in all the three bands.

Photometric results of the OT are listed below.
We used SDSS catalog for flux calibration.
