Rating agency Moody's has cut Japan's long-term sovereign debt rating,
citing concerns about the size of the country's deficit and borrowing
The rating was cut to Aa3 from Aa2, though Moody's also said the
country's outlook was stable.
Japan, the world's third-largest economy, has the highest public-debt
level amongst developed economies.
The 2009 global financial crisis, and this year's earthquake and tsunami
have increased the pressure on its finances.
"The rating downgrade is prompted by the large budget deficits and the
build-up in Japanese government debt since the 2009 global recession,"
Moody's said in its statement.
"The March earthquake also undermined Japan's recovery from the 2009
global recession," it added.
Japan's economy is currently in a recession, and has contracted for three
According to the latest government figures, Japan's economy shrank by an
annualised rate of 1.3% in the three months to the end of June. It shrank
0.3% from the previous quarter.
While that figure was better than many analysts had expected, there are
concerns about the increased levels of borrowing and spending that Japan
will have to undertake to rebuild after the tsunami.
Not least because the devastation caused by the natural disasters has
seen consumer and corporate spending in Japan soften. With consumers and
companies spending less, the government is set to earn fewer yen in tax
revenues, further impacting their budget plans.
At the same time, Moody's warned that power problems may cap the ability
of the economy to rebound quickly.
Japan's electricity production has been compromised by the crisis at the
Fukushima Daiichi nuclear power plant, which was damaged by the the
earthquake and tsunami. The government has cut the country's nuclear
power output and is asking people to limit their use of electricity.
The fear is that continuing uncertainty about the supply of power will
deter or delay investment by both the public and private sectors.
"These developments further hamper the economy's ability to achieve a
growth rate strong enough to steadily reduce the budget deficit," Moody's
