report on behalf of Nayuta team and OISTER collaboration:

We observed the field of GRB 140629A (A. Y. Lien et al., GCN 16477)
with Nishiharima Infrared Camera (NIC) attached to the Nayuta 2-m
telescope at the Nishi-Harima Astronomical Observatory.

The observations were conducted on 2014-06-29 at 14:27-15:32 UT.
We detected the near-infrared afterglow in J, H and Ks bands.

Photometric results of our observations are listed below.
We used 2MASS 16355059+4151367, 16355050+4151433, and 16355992+4151103
as reference stars for photometry.
