More than four hundred thousand women from the Asia-Pacific region were drafted or cheated into military sexual slavery by Japan during WWII. To date, the Japanese government has yet to issue official apology for this crime against human rights. In this paper, I examine the historical trajectories involved in the issue of Taiwanese “comfort women,” and to analyze written documents on these grandmothers, along with their testimonial narratives as presented in the first documentary film about Taiwanese “comfort women,” A Secret Buried for Fifty Years: Taiwanese Comfort Women (1998). The first part of my article briefly outlines the history of Taiwan’s colonization under Japan and the recruitment of military sexual slaves on the island, then discusses the rise and backlashes against the redress campaign for the grandmothers vis-a-vis Taiwanese internal political struggles; the second part comprises an analysis of the life narratives of the grandmothers as represented in the film, as well as their affective responses to the sexual violence and violation they have experienced, especially in relation to the issue of language.
