The economy grew less than initially reported in the second quarter due to a greater-than-anticipated fall in private inventory and capital investment, revised data released Friday by the government showed.

Gross domestic product rose at a 2.3 percent annualized rate in the April-June period, lower than the Cabinet Office's preliminary reading of 3.7 percent growth.

The second quarter saw Japan's first growth following four straight drops through the January-March period. However, the revised data indicated a less-than-robust recovery.
