ABSTRACT As governments develop immigrant integration policies, they draw on and express conceptions about what successful integration looks like—what we call “imagined integration.” Yet this imagination likely displays variation that matters for implementation: integration policymaking is increasingly multilevel as it involves subnational layers of bureaucracy, and it may differ across national contexts which have distinct immigration experiences and political dynamics. In response, we trace the logics within Japan's approach to integrating a range of immigrants (“multicultural coexistence”) as its objectives pass through to subnational (prefectural) governments. As a major industrialized economy, Japan is instructive because its centrally organized approach to integration differs from Western cases, and yet its growing policy attention to integration typifies trends in neighboring Asian countries facing similar demographic and economic challenges. Through the first comprehensive content analysis of all available prefectural plans regarding multicultural coexistence ( N = 31 as of 2025), we identify how subnational policymakers conceive coexistence, its justification, and its successful achievement on paper. Our study contributes to better connections between empirical understanding of important policies affecting immigrants in a key world region, as well as to theorization about the ideational aspects of policymaking.
