Kinda late, but as nobody jumped in on this:
Japanese education is a bit of a question mark. It works for them (sort of) but I have no clue about Phillipino culture.
Anyways, the very basic breakdown is:
Primary, Middle, and High School are pretty intensive (some Saturday schools), and the Juken to get into ANY levell is hard. Some people say that your college is determined on the preschool you get in, and your job is determined by the college you graduate from. While the former may be a slight exagerration, it holds a bit of truth, and the latter holds quite a bit of truth.
The kicker about college, is that after busting your nads on the test to get in, it's all down hilll at a rapid pace. They way they see it in Japan is that your life is over once you start working, so let 'em enjoy their last 4 years of life.
The best place you can look is probably Google. With the explosion of Japanese pop culture in the west in the last decade, there's bound to be a mountain of information on this. I think what you'll find though are more details on what I've found above.
