In the second quarter, GDP rose 0.7% over the previous quarter in seasonally adjusted annualised terms, which was half the revised 1.4% rise recorded in the first estimate released on 13 August. Moreover, the reading was well below the 5.3% rise tallied in the first quarter (previously reported: +5.5% quarter-on-quarter saar) and undershot the 1.0% increase anticipated by market analysts. The deterioration over the initial estimate was mainly caused by a weaker performance in the domestic sector. Private consumption expanded a mild 0.5% in the second quarter (previously estimated: +0.6% qoq saar), while government spending rose 0.6% (previously estimated: +1.2% qoq saar). Meanwhile, private non-residential investment increased 5.6% (previously estimated: +6.3% qoq saar). Exports of goods and services expanded 5.0% over the previous quarter in annualized terms (previously estimated: +4.8% qoq saar), while imports rose 6.7% (previously estimated: +6.4% qoq saar). As a result, the external sector's annualised net contribution to overall growth remained unchanged at the minus 0.1 percentage points initially reported. The Bank of Japan expects economic activity to expand between 2.1% and 2.4% in the fiscal year ending in March 2013 before, moderating to a range of between 1.5% and 1.8% in the following fiscal year. Based on the passage above, How did the weaker performance in the domestic sector affect Japan's GDP growth in the second quarter, particularly in private consumption and government spending?
