TOKYO, Aug. 6 (Xinhua) -- Tokyo stocks closed marginally lower Monday as ongoing international trade tensions triggered by the U.S. weighed on the market here, negating earlier gains made on solid earnings reports recently from Japanese firms.

The 225-issue Nikkei Stock Average edged down 17.86 points, or 0.08 percent, from Friday to close the day at 22,507.32.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, lost 9.68 points, or 0.56 percent, to finish at 1,732.90.

Metal product, bank and precision instrument-linked issues comprised those that declined the most by the close of play.
