TOKYO, Oct 5 (Reuters) - Japan's Nikkei breached a key psychological level on Wednesday, lifted by retailers, although sentiment remained tentative compared with global peers that were boosted by the prospect of central banks tempering their aggressive tightening policies.
The Nikkei share average broke through the key barrier of 27,000 for the first time since Sept. 22, and closed 0.48% higher at 27,120.53 on Wednesday.

Despite strong performances from individual stocks, the market lacked clear direction with many domestic participants awaiting further signs of economic health from the United States, including the release of key jobs data later in the day.

Fast Retailing Co Ltd rose 0.92% and had the biggest positive impact on the Nikkei after announcing an 11% year-on-year sales increase at domestic Uniqlo stores. The number of its customers declined 2.9%, but average spend was up 14.4% due to price increases and stronger sales of fall/winter items.
