Japan's exports rose 5.4 percent in December from a year earlier, posting the first gain in 15 months, government data showed on Wednesday, reflecting a pick-up in global demand and effects of a weaker yen.
The rise in the value of exports compared with a 1.2 percent increase expected by economists in a Reuters poll. It followed a 0.4 percent year-on-year decline in November, the Ministry of Finance data showed.
Imports fell 2.6 percent in December, versus the median estimate for a 0.8 percent decrease.
That brought the trade balance to 641.4 billion yen ($5.63 billion) in the black, versus the median estimate for a 270 billion yen surplus. It was the fourth straight month of surplus.
