Japan’s factory output fell for the first time in three months in November, data showed on Monday, a sign that weak emerging market demand continues to cloud prospects for a sustained recovery in the world’s third largest economy. Industrial output fell 1.0 percent in November from the previous month, more than a median market forecast for a 0.6 percent decline, trade ministry data showed. “Factory output is moving sideways,” the government said, keeping its assessment on industrial production unchanged from last month.
