Profile
My current research focuses on the legal and social history of the Ryukyu Kingdom (present-day Okinawa) and certain regions of early modern Japan, such as the Kumamoto domain, during the eighteenth and nineteenth centuries. I investigate how these societies engaged with, studied, and assimilated the legal knowledge of contemporary Qing China. Drawing upon judicial archives, I examine how local magistrates conceptualized Chinese law as a form of knowledge and how regional communities—whose customary practices diverged significantly from those of China—negotiated and internalized a normative order originating from an external cultural sphere.
My work also attempt to explore the structures of family, property inheritance, marriage, and sexuality in these regions, situating them within a broader comparative framework between Japan and Qing China. This approach seeks to illuminate the circulation and localization of legal knowledge in East Asia as well as the complex interplay between law and custom.
I received my Ph.D. in History from Kyoto University in 2021 and joined the Department of Japanese Language and Culture, School of Foreign Languages, Peking University in 2022.
