TOKYO, Sept. 8 (Xinhua) -- Japan's economy grew an annualized 2.2 percent in the April-June quarter, an upward revision from the preliminary estimate of 1.0 percent, government data showed Monday.

The revision reflected stronger-than-expected personal consumption and improved inventory figures, according to data from the Cabinet Office.

Personal consumption, which accounts for more than half of GDP, was revised upward from a 0.2 percent increase to a 0.4 percent rise, supported by higher spending on dining out, game software, and personal computers.

Private inventories, initially estimated to subtract 0.3 percentage points from growth, were adjusted to a smaller drag of 0.04 points.

However, business investment was revised downward, from a 1.3 percent gain to 0.6 percent, reflecting weaker spending on software and service-related sectors.

Exports and imports remained unchanged from the preliminary report, with exports up 2.0 percent and imports up 0.6 percent.

The Cabinet Office stated that real GDP has posted positive growth for five consecutive quarters, indicating that the economy continues to recover moderately. ■
