(Updates to close)
TOKYO, Nov 21 (Reuters) - Japan's Nikkei average ended at a 16-month closing low on Wednesday, as a stronger yen and a weaker outlook for the U.S. economy depressed exporters such as Honda Motor Co Ltd .
The Nikkei ended down 2.5 percent or 373.86 points at 14,837.66, its lowest close since July 24, 2006.
The broader TOPIX fell to a more than two-year low, down 2.1 percent at 1,438.72. (Reporting by Taiga Uranaka)
