Kawai (Tokyo  \nTech) report on behalf of the MITSuME collaboration:\n\nWe performed optical imaging observation of the field of GRB 080905A\n(C. Pagani et al. GCN 8180) with the 3-color 50cm MITSuME Telescope at\nAkeno, Japan from 12:40:12 UT (42min after the trigger) to 14:32:07 UT.\nIn the co-added images of Ic, Rc, and g' bands, we did not detect any\nafterglow candidate in the XRT error circle. The 3-sigma limiting\nmagnitudes based on USNO-B1.0 (I-band) and NOMAD (R-band,g'-band)\nstars are following:\n\nFilter Start(UT) End(UT)  Exposure   LimitMag\n---------------------------------------------------\ng'     12:40:12  13:14:31 30 x 60 s  17.1\nRc     12:40:12  13:14:31 30 x 60 s  17.6\nIc     12:40:12  13:14:31 30 x 60 s  17.6\n---------------------------------------------------",
