We observed the field of GRB 110106A (Mangano et al., GCN 11520) in Rc-band,
using the 1.3m ISAS-Kanazawa telescope, located at Sagamihara.
The observation started on Jan 6.64375 UT at ~2 min after the burst.
No any new source was found within the revised position of X-ray
counterpart (Osborne et al., GCN 11526), down to the 3 sigma upper limit
of Rc~17.6 mag.
