TOKYO, Aug 06 (NHK) - Tokyo's benchmark stock index has posted a record intraday gain, after rebounding from its worst-ever single-day points decline.
The Nikkei 225 surged right from the start of Tuesday's trading on the Tokyo Stock Exchange.
The Nikkei briefly rose 11 percent, or almost 3,500 points, beating the previous record intraday increase of 2,677 set in October 1990.
Investors are buying back shares on Tuesday after the Nikkei plummeted by 4,451 points on the previous day.
That was far more than the Black Monday crash of 1987.
The rebound has also been backed by a weaker yen.
The yen was trading at the 145-level against the dollar early Tuesday afternoon.
The Japanese currency appreciated to the 141-yen range on Monday, a level not seen in about 7 months.
Investors are selling yen and buying dollars for profit-taking on Tuesday.
Market sources say the yen weakened as concerns about the outlook of the US economy eased.
That's prompting investors to buy back mainly export-related shares.
