One thing for sure, Japan is shrinking. With only 1.34 kids per family, thats not enough to sustain itself.
According to CNN companies such as Canon in Japan are telling workers to go home at 5:30 to go have kids. Its almost amazing how different these policies are with their neighboring China which has a one child policy.
Hey here is an idea. Why not open the doors to more Chinese immigrants to Japan? Make it an effort to overcome a xenophobic past and embrace a distant cultural brother? You think it will work?
