TOKYO - Tokyo stocks edged lower in the morning session Friday, tracking a sluggish performance on Wall Street and after moves by central banks in China and Europe to boost growth failed to impress investors.

The benchmark Nikkei 225 index at the Tokyo Stock Exchange was down 0.36 percent, or 32.34 points, to 9,047.46, while the broader Topix index of all first-section shares dipped 0.2 percent, or 1.52 points, to 774.85.
