 This is Japan's second-longest post-war growth period |
Japan's economy grew faster than it previously thought in the first quarter of 2006 - rising by an annualised rate of 3.1%. Official data from the Bank of Japan had earlier put the figure at 1.9% - which itself was nearly double what analysts had expected.
Under the revised figures, GDP rose 0.8% compared to the last quarter of 2005, Japan's Cabinet Office said.
The new data shows Japan is well on the road to economic recovery.
It will also prompt further speculation that zero interest rates may soon end.
Japan's Nikkei index closed 0.56% higher on Monday having suffered last week amid concerns that rising US interest rates would stem growth and hit Japan's export market.
Japan's economy is experiencing its second longest growth period of the post-war era.
