Japan expects slump in economy

Japan says it expects its economy to shrink by 3.3% over the coming year - the country's worst slump in at least half a century.

The news comes as the government prepares to present a 15.4 trillion yen ($159bn; £109bn) economic stimulus plan to parliament.

The projected downturn for the 2009 fiscal year would be the worst since Tokyo began measuring growth in 1955.

It follows an estimated decline of 3.1% in 2008, the government said.

Finance Minister Kaoru Yosano said the world's second biggest economy remained vulnerable to fresh turmoil overseas.

"Exports have plunged much harder than our expectation," he said.

Government estimates of the decline have been revised radically downward, in what officials described as quickly changing conditions.

"The global economic crisis and economic downturn is increasing in severity, and Japan's export market is rapidly shrinking," the Cabinet Office said in a statement.
