TOKYO, July 20 (Reuters) - Japan's exports rose for a seventh straight month in June led by shipments of cars and electronics, an indication external demand continues to support a gradual economic recovery and backing the central bank's upbeat economic view. Ministry of Finance (MOF) data showed on Thursday that exports grew 9.7 percent year-on-year in June, versus a 9.5 percent annual gain expected by economists in a Reuters poll. It followed a 14.9 percent year-on-year rise in the previous month. The data comes hours before the Bank of Japan ends a two-day rate review, at which it is expected to raise its growth forecasts as robust exports and private consumption heighten prospects of a moderate economic recovery. However, the central bank is also likely to cut its price forecasts and hold off from expanding stimulus, highlighting a gap between strong growth and weak inflation. Some analysts say net exports - or exports minus imports - may have trimmed gross domestic product growth in the April-June period as the pace of export growth likely slowed from the previous quarter while imports surged. Japan's economy grew at an annualized 1.0 percent at the start of this year, posting a fifth straight quarter of growth. Whether it can extend gains depends on the strength of domestic demand, which has been a soft spot in the world's third largest economy, they say. "The economy likely expanded for a sixth straight quarter in April-June as private consumption and pubic investment probably turned out strong," said Masaki Kuwahara, senior economist at Nomura Securities. 7.1 percent in June from a year ago, posting a fifth straight month of gains, due to increased shipments of cars. The trade surplus with the United States fell 4.9 percent to 587.4 billion yen ($5.25 billion) due as imports jumped 19.3 percent in the year to June, led by crude oil and coal. Japan's trade surplus has been a target of criticism by U.S. President Donald Trump's administration, which has called for cutting U.S. trade deficit and boosting exports under his "America First" protectionist policies. Exports to China, Japan's biggest trading partner, increased 19.5 percent year-on-year in June, led by shipments of car parts and semiconductor production equipment. In terms of volume, Japan's overall exports rose 4.0 percent, up for a fifth consecutive month. Japan's imports rose 15.5 percent in the year to June, versus the median estimate for a 14.6 percent annual gain, led a surplus of 439.9 billion yen.
