The important kind of deflation is not the decline of consumer price index. The really harmful variety is credit deflation, a.k.a. credit crunch. As you can observe, the Japanese credit crunch was a severe one. The economy has not recovered yet from its aftermath.
A question arises: Should the European Central Bank hasten with some sort of quantitative easing to alleviate the proceeding credit crunch? Yes or no, it does not matter much. The real problem is not the lack of money. The problem is the lack of debtors with an acceptable rating (when speaking about corporations) or scoring (when talking about households.) The ECB may create as much money as it wishes, in theory. In practice, it can hardly push it into circulation.
Eurozone had probably entered the "Japanese scenario" in 2009 when the credit deflation actually began. Too bad that economists and politicians have been preoccupied with price inflation only. They haven't noticed the monster coming.
