Dual citizenship was once universally reviled as a moral abomination, then largely marginalized as an anomaly. During the twentieth century, states were able to police the status and manage incidental costs to the extent that full suppression proved impossible. More recent decades have seen wide acceptance of dual citizenship as those costs dissipated for both states and individuals. Powerful nonresident citizen communities have played a crucial role in winning recognition of the status. A handful of states -- Japan notable among them -- have held out against this clear trend and increasingly vocal emigrant and immigrant constituencies and children of bi-national couples. This session will situate Japan's resistance to dual citizenship in a global historical context.
