From Bride to Candidate at 18: Aligning Electoral Eligibility with Marriage Eligibility in Japan

In Japan, women can marry at 18 but cannot run for the House of Representa-tives until 25 or the House of Councillors until 30. This paper argues that thisinconsistency systematically excludes women during their peak reproductiveyears from political representation, producing legislators who—by the struc-tural conditions of their own success—lack direct experience of the policies theycreate. We propose aligning electoral eligibility with marriage eligibility at age18. This proposal draws on extensive historical evidence demonstrating thatJapanese women historically exercised significant religious, political, and eco-nomic authority. We posit that what is commonly termed “Japanese patriarchy”is not an indigenous tradition but a product of successive foreign importations:Chinese Confucianism and, decisively, Western legal frameworks during the Meijiera modernization. Extending postcolonial feminist critiques, this paper framesJapan not as a unique cultural exception, but as a critical case study of howstate-led modernization can paradoxically dismantle indigenous forms of female agency. Finally, we distinguish structurally between gendered outcomesdriven by preference (e.g., in STEM) and those driven by legal exclusion (e.g.,electoral age limits), arguing that the latter requires immediate institutional cor-rection.
