Nikkei ends flat after hitting 7-week high, profit-taking weighs
* up for 3rd day
TOKYO, Sept 11 (Reuters) - Japan's Nikkei average ended little changed on Wednesday, after hitting a seven-week high on receding worries over Syria and the yen's slide against the dollar, with profit-taking in recently strong Olympics-related shares eroding early gains. The benchmark Nikkei was virtually flat at 14,425.07, after rising to as high as 14,561.46, its highest intra-day level since July 25. The index climbed 4.1 percent over the past two days ended on Tuesday, buoyed by euphoria over Tokyo's winning bid for the 2020 Olympics and Japan's strong second-quarter growth. The broader Topix eased 0.1 percent to 1,189.25 in moderate trade, with 3.44 billion shares changing hands, the second-highest in 7-1/2-weeks.
