TOKYO, Oct 5 (Reuters) - Japan's Nikkei average fell 0.6 percent to hit an 11-week closing low on Monday, dented by shares of exporters on concerns over the fragility of the U.S. economic recovery and lingering worries about the yen's recent strength.
But a surge in shares of Fast Retailing, which saw domestic same-store sales at its Uniqlo casual-clothing chain jump 32 percent in September, provided support to the benchmark index, which earlier moved in and out of negative territory.
The Nikkei slipped 57.38 points to 9,674.49, its lowest finish since July 21.
The broader Topix declined 0.8 percent to 867.28. (Reporting by Aiko Hayashi)
