For now, the global winds are at Japan's back.

President-elect Donald Trump's promise to fire up U.S. growth by cutting taxes and developing a trillion dollars of infrastructure has helped fuel a dollar rally that's weakened the yen by nearly 8.5 percent since the day before the election, almost certainly bringing relief to Japanese policy makers.

Add rising oil prices, the likelihood of higher interest rates in the U.S. and a global shift toward fiscal stimulus to spur growth, and you have a recipe for Japan's economy gaining some traction next year.
