Japan's export growth was seen slowing in September after a series of natural disasters disrupted business activity, a poll found on Friday, but the setback was seen as temporary.

Exports were expected to increase 1.9 percent in September from a year earlier, the Reuters poll of 17 economists showed, after rising 6.6 percent in August.

Imports were seen up 13.7 percent in September from a year earlier, led by higher oil prices. The trade deficit was forecast at ¥50 billion ($445 million).
