Japan lost decade came later than you think.
“Why did Japan stagnate starting in 2008? It’s not clear. Potential culprits include the global financial crisis, the big earthquake and nuclear accident of 2011, the subsequent shutdown of nuclear power, rapid aging, the retirement of the Baby Boom generation, and the ramping up of Chinese competition. Perhaps it was all of these combined. But whatever the reason, 2008 was the turning point.”
