Tokyo share prices fell broadly Tuesday as investors reacted with shock and concern to Yamaichi Securities Co.'s decision to shut down.
The benchmark 225-issue Nikkei average plummeted 854.05 points, or 5.1 percent, to end the day at 15,867.53. The Nikkei plunged more than 900 points at one point in afternoon trading.
The fall snapped a two-day upturn that followed a 884.11-point plunge last Wednesday, the steepest decline this year. The Tokyo Stock Exchange was closed Monday for a national holiday.
