GDP per capita graph for South Korea and Japan, 1990–2026.jpg

Surprisingly, the time when Japan hit its highest GDP per capita in history
wasn't right before the bubble burst in the 90s, but in 2012 ($49,000).
Immediately after the Great East Japan Earthquake, Japanese capital overseas was massively repatriated,
causing a temporary phenomenon of an ultra-strong yen.
However, due to Abenomics, it began to drop below $40,000 starting in 2014.
And it hasn't been able to recover since then.
South Korea is expected to surpass even that temporary $49,000 peak reached by Japan next year.
If they maintain the weak yen, import prices will skyrocket, real income will decrease, and above all, the nation's economic scale will decline.
Yet, if they raise interest rates to move toward a strong yen, they cannot handle the astronomical government debt and the interest rate bomb.
How will Japan solve this?
