To help raise government revenue, Japan adopted legislation in 2012 to gradually raise the consumption tax rate to 10% by 2015, beginning with a hike from 5% to 8% implemented in April 2014. That increase had a contractionary effect on GDP, however, so PM Abe in late 2014 decided to postpone the final phase of the increase until April 2017 to give the economy more time to recover. Led by the Bank of Japan’s aggressive monetary easing, Japan is making progress in ending deflation, but demographics - low birthrate and an aging, shrinking population - pose major long-term challenges for the economy.
