From The Economist:
Just over 13m foreigners, 11m of them Asian, came to Japan in 2014, up nearly 30% compared with a year earlier and half as many again as in 2010
Chinese arrivals have jumped by more than four-fifths since 2013, and 450,000 mainlanders came for the week of the Chinese new year in February alone
Says The Economist:
A huge incentive is the weakness of the yen thanks to the Bank of Japan's monetary easing.
