TOKYO (Reuters) - Japan's Nikkei share average fell 2.8 percent on Friday to hit a six-month low after U.S. tech shares posted their biggest fall in two-and-a-half years over concerns about their expensive valuations, with the rising yen also a factor.
The Nikkei dropped to as low as 13,887.23, edging near its October 8 trough of 13,748.94.
