H. Terada, T.-S. Pyo, K. Aoki, T. Hattori (Subaru Telescope/NAOJ) and
N. Kawai (Tokyo Tech) report on behalf of the Subaru GRB team:

"We observed the XRT error circle of GRB 071021 (GCNs 6963,6966) in the 
K, H, and J-bands using the IRCS instrument on the Subaru Telescope.
We detected the afterglow candidate (Castro-Tirado et al. GCNs 6968,
6971, Malesani et al. GCN 6972) in the K-band image at approximately
K~21 mag (midtime 2007-10-22 05:38 UTC).  Further observations are in
progress."
