sounds like a somewhat superficial culture thats imploding under the weight of unrealistic expectations
The Japanese are driven to succeed. Quite hard working...right from when they're kids. After "normal" school, they attend even more private schooling. This extra schooling becomes more important when you're in high school because of college entrance exams. (they also take exams to enter HS I believe). Since the aim is to get into a good school, you'd want the best preparation you can get, so a good HS is a must. I believe exams aren't standardized, and each school has their own (at least at the university level) unlike the US, where it's simply SAT/ACT. Unlike in the US, the Japanese are required to have a certain proficiency of a foreign language (= ENGLISH. I don't imagine reading the dictionary is fun) as well as a lot of other crap under their belt when they take these things. So basically it's just harder to get in to college, where the reputation of your school can greatly affect your chances of working in some company.
Business in Japan is starting to change. While previously the goal was to work in a big company that'll take care of you (and where you can pretty much stay for life), now companies are downsizing and there is no longer this stability that people found in the past. With the economy being rather poor, skilled labor is being fired and young, inexperienced people are being hired.
Opportunities for women are also opening up. While on one level this seems beneficial, on the other hand it complicates things. When women marry they're expected to take care of the family and have lots of social obligations to the extended family. Also married women have a harder time of advancing in business, as it is believed they'd have less time/energy to input in a corporation compared to an unmarried woman or male. So it's at a disadvantage for a woman to marry AND/OR have kids. Having children out of wedlock is still looked down upon (moreso than America), so women simply opt to not marry or have kids. There are a bunch of young females out there making this decision. It is the most "rational choice" for them.
I don't see any sign of the Japanese being "superficial." It's just that times are changing and the culture is adjusting. I'd like to see how this turns out and see how the TFR problem is solved. Hopefully by my lifetime. Oh, and you can't forget how crappy their economy is...
