Prime Minister Shinzo Abe's bid to vault Japan out of 15 years of deflation risks losing public support by spurring too much inflation too quickly as companies add extra price increases to this month's sales tax bump.
Businesses from Suntory Beverage and Food Ltd. to beef bowl chain Yoshinoya Holdings Co. have raised costs more than the 3 percentage point levy increase. This month's inflation rate could be 3.5 percent, the fastest since 1982, according to Yoshiki Shinke, the most accurate forecaster of the economy for two years running in data compiled by Bloomberg.
The challenge for Abe and the Bank of Japan is to keep the public focused on the long-term benefits of exiting deflation when wages are yet to pick up and, according to BOJ board member Sayuri Shirai, most people still see price gains as "unfavorable." Any jump in inflation that's perceived as excessive by a population more used to prices falling could worsen consumer confidence and make it harder to boost growth.
