(Hiroshima\nUniv.) report on behalf of the OISTER collaboration\n\nWe performed I and Ks bands imaging observations around the error\ncircle of GRB 160601A (Kocevski et al., GCNC 19478) with the optical\ninfrared simultaneous camera HONIR attached to Kanata telescope of\nHiroshima University. We started the observations at 2016-06-01 16:42\nUT. We did not find any optical-infrared counterpart of the burst.
