The index is now "only" 16% below its historic high from 1989, lol. Speaking of lost decades, it's been over 34 years.
Not true at all. First of all Japan suffered for decades from deflation. Only recently have prices modestly picked up. Inflation stands at around 2-3% in Japan. Still below any long term target rate which is why BOJ still holds jgbs at near zero rates by buying virtually every new issue. The reason the economy is slowly picking up has nothing whatsoever to do with inflation. It has to do with improved corporate governance and a return of trust by foreign investors. All that despite Japan being hopelessly behind the entire IT industry.
