There is an emerging debate about the role and importance of women in right-wing nationalist movements. Drawing on research that highlights the need to study such women as active and complex political agents, this article examines a phenomenon that has previously received little attention—the activism of female Japanese nationalists. We approach the question of how such activism is practiced by analyzing a group interview with female nationalists, a nationalist manga centering on women’s experiences, and autobiographic books on such activism by and for Japanese women. The article contributes by arguing that female nationalist agency in Japan is a complex phenomenon, which is enacted through everyday micro-practices. It outlines how female nationalist activism draws upon and enhances, as well as challenges and transcends, a traditional Japanese “housewife identity.” As such, the female Japanese nationalist is imagined as having access to certain truths. She takes on the role of “truth-teller,” who is playing a strategic role in “waking people up” to the nationalist cause by voicing anger but also making space for a more “joyful,” “cute,” and inconspicuous everyday activism.
