Japan's parliament Tuesday passed a US$142 billion extra budget that forms a key part of Prime Minister Shinzo Abe's efforts to tackle the deflation that has dogged the economy for years.[Hong Kong company registration]

The 13.1 trillion yen package squeaked by the opposition-controlled upper house of parliament less than two weeks after the lower house approved the spending.

The measure is part of a wider stimulus package announced by Abe's cabinet in January, after his Liberal Democratic Party swept December elections on a pledge to revive the world's third-largest economy.

The new money will be earmarked for various economy-boosting measures, including job growth, upgrading Japan's ageing infrastructure, and rebuilding [Set Up Company Hong Kong]disaster-struck areas hit by the 2011 quake-tsunami.

Plugging a public-pension financing gap was among the other spending measures.

The total package could top 20 trillion yen if spending by local governments and the private sector was included.

Japan's economy fell for a third straight quarter between October and December, leaving it mired in recession due to weak export demand, and stirring fears about its ability to recover.

Abe has pledged to pull Japan out of years of falling prices, which dampen demand and business investment, through big spending and aggressive monetary easing.

He has pressured the Bank of Japan for such policy measures, with a new central bank chief set to be nominated as early as this week.

Abe has also [Hong Kong Company Formation]said he would boost defense spending. Japan is embroiled in territorial disputes with China and South Korea, while North Korea jangled regional nerves earlier this month with its third nuclear test.

But the big spending plans have stoked fears over Japan's already tattered fiscal health, the worst among industrialized nations.
