Japan has an inflation problem - it does not have enough.

Instead, for almost two decades, the country has suffered from on-and-off deflation, or falling prices.

On Tuesday, in an effort to draw a line under the years of deflation, the central bank agreed to double its inflation target to 2% and to keep spending until things have turned around.
