Based on the lives and crimes of no less than twenty real women, dokufu (poison women) narratives emerged as a powerful presence in Japan during the 1870s. During this tumultuous time, as the nation moved from feudalism to oligarchic government, such accounts articulated the politics and position of underclass women, sexual morality, and female suffrage. Over the next century, the figure of the oversexed female criminal, usually guilty of robbery or murder, became ubiquitous in modern Japanese culture.  In Poison Woman, Christine L. Marran investigates this powerful icon, its shifting meanings, and its influence on defining women’s sexuality and place in Japan. She begins by considering Meiji gesaku literature, in which female criminality was often medically defined and marginalized as abnormal. She describes the small newspapers (koshinbun) that originally reported on poison women, establishing journalistic and legal conventions for future fiction about them. She examines zange, or confessional narratives, of female and male ex-convicts from the turn of the century, then reveals how medical and psychoanalytical literature of the 1920s and 1930s offered contradictory explanations of the female criminal as an everywoman or a historical victim of social circumstances and the press. She concludes by exploring postwar pulp fiction (kasutori), film and underground theater of the 1970s, and the feminist writer Tomioka Taeko’s take on the transgressive woman.  Persistent stories about poison women illustrate how a few violent acts by women were transformed into myriad ideological, social, and moral tales that deployed notions of female sexual desire and womanhood. Bringing together literary criticism, the history of science, media theory, and gender and sexuality studies, Poison Woman delves into genre and gender in ways that implicate both in projects of nation-building.  Christine L.
