Ryosuke Kakinuma is a historian specializing in ancient East Asian history with a focus on border regions, diplomatic relations, and island studies. He serves as a Teacher at Waseda University Senior High School and holds part-time lecturing positions at Hakuoh University's Faculty of Education and Waseda University's School of Education. His academic work bridges high school education with university-level research, particularly in the field of history education.
Dr. Kakinuma earned his Master's degree from the University of Tokyo's Graduate School of Humanities and Sociology, specializing in Japanese History. He began doctoral studies at the same institution but withdrew after completing coursework. His academic journey began at Musashi High School, continued at the University of Tokyo's College of Arts and Sciences, and culminated in his specialization in Japanese Cultural Studies with a focus on Japanese History.
Dr. Kakinuma's research centers on historical dynamics of border regions in ancient East Asia, particularly islands like Tsushima that served as cultural and diplomatic bridges between Japan, Korea, and China. His work examines how ancient states managed frontier territories, the movement of people across borders, and diplomatic protocols governing international relations. He has developed a unique framework for understanding 'border islands' as crucial sites for examining the interplay between central authority and local autonomy in historical contexts.
His recent publications demonstrate a clear trend toward comparative studies of border regions across East Asia, with emphasis on how historical understandings of borders can inform contemporary history education. Kakinuma has pioneered educational programs using Tsushima Island as a living classroom for examining Japan-Korea relations, creating innovative curricula that help students understand complex historical dimensions of border regions.
- Received research funding from Japan Society for the Promotion of Science
- Secured grants from Suntory Foundation and Mishima Kaiun Memorial Foundation
- Developed multiple research projects on historical border regions and educational applications
As an educator, Kakinuma developed the 'Cross-border Tsushima' project, engaging Japanese and Korean students in collaborative historical research since 2015. This initiative has adapted to changing circumstances, including the pandemic, by incorporating online dialogue components while maintaining its core mission of using historical border regions to foster cross-cultural understanding.
His research team includes collaborators from Waseda University, Meio University, and Korean institutions including Korea University, creating a transnational network focused on comparative border studies. The 'Cross-border Tsushima' project has become a model for international educational collaboration, bringing together students and scholars from multiple institutions to examine historical border regions through both academic research and direct field experience.
