TOKYO, Aug. 7 (Xinhua) -- Tokyo stocks advanced Tuesday morning with the market mood lifted by heavily-weighted SoftBank Group's jump after the release of its robust earnings, although investors remained edgy amid ongoing international trade frictions eyeing Japan-U.S. talks on Thursday.

The 225-issue Nikkei Stock Average gained 54.78 points, or 0.24 percent, from Monday to 22,562.10.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, added 2.56 points, or 0.15 percent, at 1,735.46.

Information and communication, insurance, and oil and coal product-linked issuers comprised those that gained the most by the morning break.
