Aug 30 - Japan's Nikkei average rose 3 percent on Monday after the yen slipped as the Bank of Japan began an emergency policy meeting and after revised second quarter U.S. GDP was less gloomy than expected.
Expectations that steps by Japanese authorities aimed at stemming strength in the yen led to short-covering, particularly in shares of exporters, though gains could lose steam if there are no major surprises from the BOJ meeting, market players said.
The benchmark Nikkei .N225 gained 267.25 points to 9,258.31, after rising 1 percent on Friday.
The broader Topix .TOPX added 2.3 percent to 838.50.
The Bank of Japan began an emergency meeting on Monday to ease monetary policy, bowing to strong government pressure to try to curb a rise in the yen that is threatening a fragile economic recovery. [ID:nTOE67T00F] (Reporting by Aiko Hayashi; Editing by Edwina Gibbs)
