My immediate take on learning of Norimitsu Onishi's article on the KenKanRyu (嫌韓流, i.e., "Against* the Korean Wave") book was that he'd yet again managed to completely miss the point, and in so doing painted a highly misleading impression for all those Western readers whose only knowledge of East Asia comes through news organs like the NYT. As it turns out, I'm not alone in feeling this way: The Marmot's Hole makes the same point I did in noting that the feelings of contempt and dislike expressed in the book are far from one-sided, while a commenter named Matt argues in his blog that Onishi engaged in selective, out-of-context quotation of material to juice up the story.
The facts of the matter are simple: the attitudes reflected in this manga are hardly a harbinger of some imminent return to the bad old days of Japanese militarism, the sentiments are far from exclusive to Japan but actually far more virulent on the Korean side, and the history laid out in the book, while highly distorted, contains enough truths of the sort Koreans cannot bring themselves to admit to that it gives the entire undertaking a lustre of credibility in Japanese eyes (which is how all effective propaganda works, by the way). Finally, a sales run of 360,000 in a market of 80 million manga consumers simply isn't all that high, and one can only wonder how many of those buyers picked up the book precisely because of the controversy it stirred up, to see what the outcry was all about. Norimitsu Onishi's article does the facts a great disservice, and is so lacking in balance and context that it reads almost like a PR dispatch by the Korean government: one would never guess from it that opinion polls show that the Japanese entertain far more favorable attitudes towards their Korean neighbors than the Koreans do towards them.
*A more literal translation than the inflammatory alternative Onishi opts for.
