Tokyo stocks edged higher on Friday morning as a halt in the yen's appreciation against the U.S. dollar bolstered investor sentiment to a point, but some players were circumspect ahead of the start of Group of Seven finance chiefs' two-day meeting.

The 225-issue Nikkei Stock Average added 30.99 points, or 0.19 percent, from Thursday to 16,677.65.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, gained 3.04 points, or 0.23 percent, to 1,339.60.

Notable gainers comprised textiles and apparels, and electric power and gas-linked stocks.
