Climate change and disasters in Japan highlight gendered vulnerabilities rooted in socio-cultural norms, economic disparities and institutional challenges. Regardless of its sophisticated disaster management system, gender-based disparities in Japan persist, which makes inclusive and sustainable approaches towards women and other vulnerable communities critical. Research has documented that women experienced significantly higher psychological stress than men following the 2011 Great East Japan Earthquake.The increased burden of traditional care roles has spurred these disparities. Official surveys indicate that women constitute a significant majority of post-disaster shelter dwellers and face heightened risks of sexual violence and economic insecurity. This study critically evaluates policy directions of the Government of Japan in promoting women’s leadership in decision-making processes of disaster management, developing gender statistics, and allocating funds to the organisations working for women. The study also reviews Japan’s dual role as a reformer of its national policy and a regional leader of the Asia and Pacific. Findings highlight the need of collaborative intersectional approach involving various stakeholders from academia, non-profit organisations (NPOs) and corporate entities. Re-evaluation of care is suggested as a key to rejuvenating approach in the framework of feminist political ecosystem.
