TOKYO, Feb. 5 (Xinhua) -- Tokyo stocks extended losses on Monday morning following Wall Street's sale-off at the end of last week on speculation that U.S. interests rates may be hiked more quickly than expected while rising U.S. Treasury yields continued to rattle nerves.
The 225-issue Nikkei Stock Average tumbled 565.51 points, or 2.43 percent, from Friday to 22,709.02.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, fell 40.13 points, or 2.15 percent, to 1,824.07.
On the main section, all industry categories retreated into negative territory, with mining, nonferrous metal and real estate-linked issues comprising those that declined the most by the morning break.
