The book's title is misleading.Sonia Ryang is a specialist of Korea, Koreans living in Japan, etc.This book (which is not academically rigorous, rather an essay conveying author's subjective views) serves principally the personal fight of Ryang against anti-korean discrimination in Japan, and for recognition of damage to countries colonized by imperial Japan... love as a subject is only a pretext.Ryang also stresses her view of Japanese state as manipulating (even now) its population, along the whole book.What is particularly disturbing is to use these fights in her attempt to describe love in Japan.However, the only good point (once you remove the anti-antikorean and state-conspirationist interpretations of love) is that this essay exposes the evolution of love and sex relations along Japan's history.The disturbingly biased parts are only when she comes to contemporary era, and puts in all (nowadays') Japanese lovers heads antikorean images and state manipulation, as if it was even remotely pertinent (at least when it comes to love emotions).
