TOKYO, May 18 (Xinhua) -- Tokyo shares closed higher on Friday as a weak yen versus the U.S. dollar lifted exporter issues, with the market mood also buoyed by potentially easing global trade issues.

The 225-issue Nikkei Stock Average added 91.99 points, or 0.40 percent, from Thursday to close the day at 22,930.36.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, gained 6.88 points, or 0.38 percent, to finish at 1,815.25.

Oil and coal product, mining and insurance-linked issues comprised those that gained the most by the close of play.
