TOKYO, July 13 (Xinhua) -- Tokyo stocks closed higher Friday as investor sentiment was bolstered by the yen's soft tone and domestic firms reporting solid earnings.

The 225-issue Nikkei Stock Average added 409.39 points, or 1.85 percent, from Thursday to close the day at 22,597.35.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, gained 20.39 points, or 1.19 percent, to finish at 1,730.07.

Investors' risk appetite was bolstered by the yen's retreat against the U.S. dollar in early trade, brokers here said, coupled with gains made on Wall Street overnight.

They added that shares were solid throughout the day, as robust domestic earnings reports helped support hopes that Japan Inc. in general would announce upbeat earnings during reporting season.

By the close of play, service, textiles and apparel, and precision instrument-linked issues comprised those that gained the most, and rising issues beat falling ones by 1,547 to 473 on the First Section, while 80 ended the day unchanged.

On the main section Friday, 1,278.36 million shares changed hands, rising from Thursday's volume of 1,192.58 million shares.

The turnover on the final trading day of the week came to 2,547.2 billion yen (22.59 billion U.S. dollars).
