Japan's Nikkei average ended down nearly one percent on Wednesday, with technology stocks taking the lead after a fall in the U.S. Nasdaq and a revenue forecast cut by blue-chip office machine maker Canon Inc <7751.T>. An unexpected downward revision to Japan's gross domestic product growth also helped prompt a pause in the bull run since late February but participants said the overall trend in the market was still up. The benchmark Nikkei <.N225> closed down 0.86 percent at 11,433.24. The broader TOPIX index <.TOPX> shed 0.52 percent to 1,128.40 after ending Tuesday at its highest since May 24, 2002.///
