The sad case of Japan's free fall is a cautionary tale of what happens when a high-flying economy has a real estate and equity bubble that goes bust, avoiding (for too long) doing the painful structural reforms and clean-up of the financial system that is necessary to avoid a lengthy, L-shaped near-depression. Japan had over a decade of stagnation and deflation, then a mild, sub-par growth recovery that lasted only three years, and is now spinning into another severe stag-deflation.
