TOKYO, Feb. 5 (Xinhua) -- Tokyo stocks closed sharply lower Monday, with the benchmark Nikkei stock index logging its biggest decline in 15 months as a sell-off late last week on Wall Street on inflation concerns triggered a risk averse mood here.
The 225-issue Nikkei Stock Average dropped 592.45 points, or 2.55 percent, from Friday to close the day at 22,682.08.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, lost 40.46 points, or 2.17 percent, to finish at 1,823.74.
On the main section on Monday, all industry categories retreated, with mining, nonferrous metal and machinery-linked issues comprising those that declined the most.
