Japanese government on Thursday revised down the country's real economic growth in the October-December period in 2010 to an annualized minus 1.3 percent from minus 1.1 percent in a preliminary report.
It was the first time in five quarters that seasonal gross domestic product had contracted.
The contraction corresponds to weaker housing, private consumption and business investment, the government said.
GDP is a measure of the total value of goods and services produced domestically./.
