What do cherry blossoms, sake, and dumplings have in common?
Instead of doing an internet search, you could find out by taking a springtime trip to Japan. United Airlines has a promotion on round-trip economy award tickets from the US (not including Hawaii) and Canada to Japan in April.
If you book before April 17, 2014, and travel between now and April 30, 2014, you can save 25% off United Saver (low-level) award economy tickets. Usually, round-trip award tickets from North America to Japan cost 70,000 miles. But with this promotion, you can travel round-trip for only 52,500 miles!
Fly United to Japan in April for Only 52,500 Miles Round-Trip
That said, it only costs 25,000 American Airlines miles for a 1-way award ticket from the US to Japan, from October 1 to April 30 so that would save you even more miles!
