Tokyo stocks fell Monday, sending the key Nikkei index to its lowest close in more than 26 years as investors were jittery about prospects for the global financial sector and Japan's economy.

The 225-issue Nikkei lost 87.07 points, or 1.2 percent, to end at 7,086.03, marking its lowest finish since Oct. 6, 1982, when it closed at 6,974.35.

The broader Topix index of all first-section issues was down 10.86 points, or 1.51 percent, at 710.53, its lowest level since Dec. 20, 1983, when it ended at 708.53.
