japJapan’s economy contracted at a larger than earlier estimated annual rate of 7.1 percent in April-June, as companies and households slashed spending following a tax hike. The revised data released Monday show business investment fell more than twice as much as estimated before, or 5.1 percent, while private residential spending sank 10.4 percent, in annual terms.
