Twin Tale: Rising China, Japan's setting sun - CNN.com
The above link is a CNN news item about twin sisters born in Japan. One stayed in Japan and the other emigrated to China. The one who emigrated is much more upbeat about her choice and does not plan to ever return to Japan.
An interesting point raised in the article is that one third of all Japanese between the ages of 20 and 30 are unemployed, and with China booming right next door the Japanese government is fearful of a brain drain.
By the year 2050 40% of the Japanese population will be over 65 years old and that there will be only 2 workers to support each retiree. If a significant number of Japanese twenty-somethings opt to seek their future in other countries, then the Japanese problem of its rapidly aging demographic will accelerate.
