Japan's economy grew at an annualized rate of 4.8 percent last quarter, the fastest pace in two years.
The third quarter GDP growth is compared to 2.7 percent in the April to June quarter and a contraction of 12.2 percent in January to March.
The growth is stoked by Japan's government stimulus measures as well as a rise in net exports.
It's the second straight quarter of growth for the world's second largest economy, which is recovering from the worst recession since World War II.
The GDP growth beat analysts expectations of a 2.9 percent gain.
