You've gotta love a book with a title that perfectly describes its contents.
The author, an American, spent 6-8 weeks each in 5 Japanese high schools that represent a spectrum of academic success, from a top college prep school to a struggling night school. He also handed out surveys to the students and interviewed teachers extensively.
The result is a well-researched examination of the Japanese high school system, both from the inside and outside. It describe the history of the Japanese school system, the perennial struggles between the leftist teachers' union and the conservative Board of Education, and above all, the towering importance of the college entrance exams which shape everything.
Even better, it's written in a comfortable, straightforward style that avoids the extremes of either academic blandness or too-comfortable chattiness.
Fair warning: It's based on a trip in the 1970's and my edition was updated in the early 1980's. Naturally, some of its information is out-of-date, but from what I've read things haven't changed that much.
I also disagree with the author's conclusion, and am disappointed that he swept Japan's teen suicide issue into an appendix where his analysis of the problem was a bit too light to my taste.
That said, the majority of the book is fascinating and provokes thought about different approaches to education.
