Correlates nicely with their location on the economic parable. Korea started to grow later than Japan (because of the civil war) and is now where Japan was about 30-35 years ago: still booming, with insane real estate costs, etc. Japan has had 20 years of stagnation - people got poorer, so now they're making kids again.
