Tokyo stocks plunged across the board Monday, with the benchmark Nikkei index closing at a 10-week low below 11,000 on sharp falls in U.S. shares at the close of trade last week due to fears of a U.S. interest rate increase.

The dollar briefly climbed to an eight-month high above 113 yen Monday afternoon in Tokyo on tumbling Japanese stocks and the release of strong U.S. employment data.

The 225-issue Nikkei stock average fell 554.12 points, or 4.84 percent, to close at 10,884.70, its lowest closing since Feb. 26, when it ended the day at 10,815.29. The Nikkei fell for the sixth straight session, and the day's loss was the largest since Oct. 23, when the Nikkei gave up 554.46 points.
