Kawai(Tokyo Tech.)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 161129A (Kocevski et al., GCNC 20210)\nin Ks-band with a wide-field NIR camera at Okayama Astrophysical\nObservatory (Japan). The camera has an effective aperture of 0.91m.\n\nObservations started from 08:44 UT on 29th November, 93 min after\nthe BAT trigger, to 09:29 UT. The total exposure of 17.3 min was\nsuccessfully obtained.\n\nIn our co-add image, we found a faint source at coordinates\n   R.A.(J2000) = 21:04:54.59\n   DEC (J2000) = +32:08:05.2,\nclose to the position reported by Beardmore et al.(GCNC 20211),\nand Klose & Stecklum (GCNC 20216).\n\nWe measured the source magnitude of Ks = 15.95 +/- 0.14 (Vega).\nThe calibration was made against 2MASS field stars.\n\nT0+[min]    MID-UT     T-EXP[min]    Ks\n------------------------------------------------------------\n  +115       09:06       17.3         15.95 +/- 0.14 (Vega)\n------------------------------------------------------------\nT0+ : Elapsed time after the burst [min]\nT-EXP: Total Exposure time [min]",
