The International Monetary Fund will revise downward its forecast for Japan's economic growth for 2001 to less than 1 percent, a senior IMF official said Monday.

IMF Deputy Managing Director Shigemitsu Sugisaki said the revision will be made when the IMF publishes the World Economic Outlook report on April 26.

The IMF projected the growth of Japan's 2001 gross domestic product at 1.8 percent in September.

Sugisaki meanwhile indicated the IMF tolerates a weak yen, believing it will boost the flagging Japanese economy.
