In this paper, I examined the “unmarried woman” in Japanese prewar literature. I compared and analyzed how the ‘unmarried’ at that time appeared and whether it was accepted or not, focusing on the works of female novelists. The main texts were Tamura Toshiko’s Akirame (1911) and Yoshiya Nobuko’s “Yaneura no Nisyozyo” (1920). In the two works, the main characters are women who graduate from elementary school and attend university (college), and are familiar with modern education and culture. And they commonly establish intimate relationships with same sex through Manless space (school, dormitory).They would have shared the girl culture that was popular among girls at the time. And I can guess that I would have seen the influence of Atarashii Onna at that time and that it was affected. Women learned only the role of the ‘good wife’ because of their existence. Ironically, the main characters in the two works that earned “ego” in modern education resist the standardized life. And they are enthusiastic about homosexual relationships through communities (schools, dormitories). The ending of these two works is a little different.They reject the ordinary life course of heterosexual marriage. And they try to become self-reliant by ‘unmarried’.Unmarried women in Japan before the war were hard to obtain even citizenship. That is why ‘unmarried’ was a different culture. And the heroines who choose ‘unmarried’ are ‘heretics’ who resist tradition and institutional authority.
