Maximilien Xavier Rehm is an Assistant Professor at the Waseda University Institute of Asia-Pacific Studies. Coming from a background of political science and international relations, Maximilien’s current primary research focus is Japanese migration policy. He has written extensively on the topic, with peer-reviewed articles published on Japan’s refugee policy, the 2019 amendment to the Immigration Control Act, and the migration policies of the second Abe administration. He is also the author of “Japan’s Modern Immigration Regime: Contradiction and Continuity” (Routledge, 2026), which places a temporal focus on the 1980s and 1990s in Japanese migration policymaking to explore the origins of the country’s current policy framework. Maximilien is also an active contributor to non-academic specialist magazines, where he focuses on contemporary Japanese politics, society, and foreign relations in addition to migration.
