TOKYO (Kyodo) -- Tokyo stocks ended down Friday, with the Nikkei index finishing at its lowest level since August, as investor sentiment was hurt by weak earnings from some major Japanese companies and uncertainty ahead of the U.S. presidential election on Nov. 3.
The 225-issue Nikkei Stock Average ended down 354.81 points, or 1.52 percent, from Thursday at 22,977.13, the lowest close since Aug. 28. The broader Topix index of all First Section issues on the Tokyo Stock Exchange finished 31.60 points, or 1.96 percent, lower at 1,579.33.
Decliners were led by pulp and paper, precision instrument and securities house issues.
The U.S. dollar retreated to the lower 104 yen zone as investors fled to the perceived safety of the yen amid risk aversion triggered by falls in Tokyo shares.

The yield on the benchmark 10-year Japanese government bond rose 0.010 percentage point from Thursday's close to 0.035 percent as the safe-haven debt was sold after overnight gains on Wall Street eased risk aversion.
