I completed an MA in International Studies at Tokyo University of Foreign Studies in 1997, an MA in History at Georgetown University in 2003, and a Ph.D. in Area Studies of China at Tokyo Woman’s Christian University in 2018. From 2003 to 2005, I worked as a research fellow at The Japan Institute of International Affairs, an affiliate of the Ministry of Foreign Affairs of Japan. Since 2005, I have been with the Institute of Developing Economies, JETRO, under the Ministry of Economy, Trade and Industry (METI), Japan. I have conducted research overseas as a visiting scholar at the Institute of European and American Studies, Academia Sinica in Taiwan (2010), and at the School of International Studies, Peking University in China (2011). During my scholarships in Taiwan and China, I focused on China–US and China–Taiwan relations, conducting research based on archival materials. I am currently researching US–China–Taiwan relations, analyzing these complex dynamics from both contemporary and historical perspectives.
