Like some of the other reviewers here, I read this book during and after my own trip to Japan. I have a minor in Japanese (and would probably declare a major if my college offered it); I've been studying the language and culture for three years, have written a number of papers on Japanese history, art, culture, language, etc., and taught English in a college and high school there during my recent trip. I have done all of this because I love Japan, and everything that goes along with it. I'm not Japanese, and I don't claim to be. Japan has many problems and flaws, and I readily admit that. However, those facts do not stop me from seeing issues in Mr. Feiler's book.
I think the biggest problem is that, while he spent a full year in Japan, Mr. Feiler still wrote the book from the perspective of an American. I don't mean to say he doesn't acknowledge or discuss the culture and history from the Japanese side of things, which he does. The problem is that his own commentary always comes with the implication of American superiority. Every discussion of cultural differences (which, as the main point of the book, is an important thing to discuss) includes some way for him to say, "Japan does things in this way, which is fine, but it's bad because in America we...," and so on. Despite his year in Japan, he still seems unwilling to admit that his own perspective is a biased and limited one. He lived in a specific school in a specific area of Japan, and writes as though that experiences makes him an expert on the whole culture.
I have a biased perspective as someone who, as I've confessed, loves Japan, but I couldn't help but feel that this book was unbalanced in its assessment of Japanese culture. There is too much negativity, which is bad for two reasons: 1) Japan, like any other human culture on our planet, has both good and bad things that deserve to be acknowledged more realistically, and 2) it implies that Mr. Feiler the authority to give some kind of rating to an entire society of people. Let me be clear: nobody, not even this man, has the authority to judge the value of a culture. I have said I love Japan, but I will not say that Japan is a better country than others or even a great country. I love it for my own personal reasons, and I don't expect other people to love it for those same reasons as though they're some kind of objective truth. The second-to-last chapter of this book actually includes a categorized set of overall assessments about the Japanese educational system and Japanese culture as a whole. It's like the judging panel for diving at the Olympics: "Oooh, Japan had good form at the beginning, but they could've been a little bit straighter coming into the water at the end!"
One of the points that other reviewers brought up is a good one: this book was published in 1991. That means that anybody reading Mr. Feiler's account of life as an English teacher in Japan is reading about experiences that took place about thirty years ago. The world has changed rapidly in the last thirty years. Taking that in combination with his biased writing and inflated sense of self-importance, that means that the reader who wants to understand Japan in the world of 2018 will receive some bad information. I'm not saying everything he says is incorrect; in fact, a lot of the things he brings up are actually still true about Japan today. It's less about accuracy and more about opinion: the person reading this book comes away with some cultural knowledge and a non-native belief about the problems it's facing and how it should work through them. As a book that should primarily be about cross-cultural understanding, I cannot over-stress the importance of the former and the danger of the latter.
