The enclave serves a dual purpose: offering refuge from social exclusion and facilitating upward socioeconomic mobility. This study extends the understanding of ethnoburbs beyond Western contexts by analysing this suburban ethnic formation. Based on six in‐depth interviews with Chinese residents and business owners and analysis of secondary sources such as census data and municipal reports, this study explores the formation of Nishi‐Kawaguchi Chinatown and its embedded ethnic business networks. The research revealed how Chinese migrants create economic niches and community spaces while facing institutional barriers in Japanese society. These patterns challenge classical and spatial assimilation theories and support a more nuanced understanding of immigrant adaptation in East Asian urban peripheries. By conceptualising the enclave as a ‘socioeconomic emergency elevator’, this study bridges two seemingly opposing perspectives on ethnic enclaves—as places of exclusion and as springboards for opportunity—and proposes a flexible, dynamic model of immigrant adaptation. The results offer theoretical and practical insights into urban studies, migration research and multicultural policies in diverse societies.\n"]
