TOKYO, Sept. 21 (Xinhua) -- Japan's Nikkei Index closed steeply lower on Tuesday, setting its largest one-day drop in three months in a plummeting global market.
The 225-issue Nikkei Stock Average finished down 660.34 points, or 2.17 percent, from Friday at 29,839.71, its lowest level since Sept. 6.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange ended 35.62 points, or 1.70 percent, lower at 2,064.55.
Japanese financial markets were closed Monday for a national holiday.
Declining issues were led by iron and steel, machinery and marine transportation issues.
Tumble in Japanese stocks came after the fall in U.S. and European stock markets on Monday, brokers said.
Japanese stocks stayed weak throughout the day, as the benchmark Nikkei set its first close below the 30,000 mark in nearly two weeks.
Tokyo stock market rose sharply last week and hit its highest level in 31 years, as the new government is expected to adopt new stimulus measures after Prime Minister Yoshihide Suga decided to resign amid a decreasing support from the public.
On the First Section, decliners outnumbered advancers 1,942 to 218, while 27 finished unchanged.
Hitachi Construction Machinery dropped 185 yen (1.69 U.S. dollars), or 5.5 percent, to 3,190 yen (29.9 dollars), as well as industrial machinery maker Yaskawa Electric declined 270 yen (2.46 dollars), or 4.4 percent, to 5,870 yen (53.53 dollars).
SoftBank Group plunged 332 yen (3.03 dollars), or 5.0 percent, to 6,329 yen (57.71 dollars).
Due to the uncertainty of global growth, stocks that are sensitive to economic fluctuations, such as shippers and steel manufacturers, have also weakened.
Kawasaki Kisen slipped 310 yen (2.83 dollars), or 4.1 percent, to 7,310 yen (66.66 dollars), and JFE Holdings sank 72 yen (0.66 dollar), or 3.9 percent, to 1,762 yen (16.07 dollars).
