Starting at 2011 March 31,07:04 UT, we performed K-band observation
of the field of GRB 110328A / Swift J164449.3+573451
(Cummings et al. GCN 11823) using the KASINICS instrument on
the 1.8m telescope at Mt. Bohyun Observatory in Korea.
We clearly detect the NIR counterpart in K (Morgan et al. 11845;
Levan et al. GCN 11846). Using 2MASS stars in the vicinity,
we obtain K ~ 16.86 +- 0.02 mag (statistical error only)
for the NIR counterpart.
The brightness of the object is consistent with the value reported
in Levan et al. (GCN 11846), implying no significant brightening over
about 18 hrs time span.
Further NIR observations are being carried out.
