The Nikkei 225 stock index briefly rose more than 3 percent Monday and closed above the 20,000 line as investors' risk appetite grew on firm U.S. jobs data and a sharp rebound on Wall Street late last week.
The Nikkei ended 477.01 points, or 2.44 percent, higher from Friday at 20,038.97. The broader Topix, which covers all first-section issues on the Tokyo Stock Exchange, finished 41.37 points, or 2.81 percent, higher at 1,512.53.
Every industry category gained ground, led by electric appliance, real estate and miscellaneous product issues.
