The economy grew a real 1 percent in the April-June quarter, the highest level of quarterly growth since the real 1.3 percent rise in the October-December quarter of 2000, the government said Wednesday.

The April-June expansion was greater than the 0.6 percent growth reported initially, according to data released by the Cabinet Office. It represented the sixth straight quarterly increase.

The figures also indicate that the world's second-largest economy is staging a recovery, the Cabinet Office said.
