The post-war havoc in Japan represented the collapse of the old power paradigms. Although the defeat brought to the Japanese people the unprecedented national humiliation and unaccountable family tragedy, for those women who used to be confined by Confucian ideology and traded on account of men's profits were given a chance to defy the male-centered power structures arbitrarily imposed upon them.In this research I conduct text analysis to re-examine the context of one of Hayashi Fumiko's representative short stories, ”River Goby,” while comparing to Hayashi's other contemporary works at the same time, to illustrate how the female protagonist struggles to resist the family narration and to pursue her libido for the first time. To facilitate the discussion, I will be applying Cixous' theory of ”ecriture feminine” to demonstrate how Hayashi uses the flowing images, such as river, rain, as a metaphor of female sexuality, and how she makes visible the ways in which the body has been gendered to produce and maintain the power economies of patriarchy.
