D. Yonetoku, T. Murakami, H. Kodaira, S. Okuno, S. Yoshinari, T. Kidamura (Kanazawa Univ.) and Y. Kobayashi (NAOJ) on behalf of the Kanazawa team report: We have observed the field of GRB 060105 (Ziaeepour et al. GCN #4429) with J, H, Ks-bands using the 1.3m telescope on the roof top of ISAS, Japan. The observation was started at 08:37 UT (1.8 hours after the burst) in poor condition and low elevation. Comparison with the 2MASS catalogue does not reveal any new source within the position of the XRT error circle. The 5-sigma upper limit magnitudes are Ks: 13.8, H: 14.2, J: 15.7, respectively.
