Conclusions

The concluding chapter situates the study’s findings within Japan’s rapidly evolving immigration landscape, where demographic pressures and political anxieties intersect with the lived realities of immigrant-origin youth. Drawing on competing theoretical models of assimilation, it argues that no single framework adequately captures the Japanese case: while patterns of upward mobility and selective acculturation are evident, trajectories of exclusion – particularly among Brazilian youth in ethnic-school paths – challenge classical predictions. The typology of linguistic adaptation further illustrates how integration is mediated by education, generational pace, and cultural proximity. Beyond theory, the chapter reflects on the symbolic politics of “becoming Japanese,” highlighting the persistence of essentialist boundaries alongside emergent, hybrid forms of belonging. Citizenship law, discrimination, and institutional practices continue to constrain integration, yet shifting identities and demographic diversification point towards gradual redefinitions of Japaneseness. Ultimately, the chapter calls for a reframing of integration debates in Japan, attentive to the interplay of history, policy, and everyday identity work.
