A sweeping study of sex, power, and knowledge in modern Japan, this ambitious work provides the first full-scale, detailed history of the formation and application of a science of sex from Meiji through mid-twentieth century Japan. Tracing the different uses made of sexual knowledge, the book brings to light the complex and subtle interplay between sexuality, scientific expertise, social control, and empire building.<br>Drawing on a wide variety of sources, Frühstück analyzes the conflicts and negotiations that aimed at producing a normative sexuality. She shows how the "colonization" of sex was enacted through debates over several issues: the necessity of sex education; the prevention of venereal diseases; the problem of masturbation and its alleged consequences; the legalization of birth control; the fight against prostitution; the emergence of eugenics; and, eventually, the implementation of "racial hygiene" policies. In <I>Colonizing Sex </I>we see how these struggles were driven by rhetoric consisting of cries for defense, liberation, and truth--emphasizing in every historical moment how the sexual body has been, and is, part of much broader currents in political, cultural, and social life.
