From sociocultural, interactional and critical perspectives, this study investigates the practices and ideologies of racial and ethnic identities and relationships surrounding Jun, a Colombian Japanese high school student, within a transnational Japanese student community at Pearl High School (pseudonym) in California. In particular, the analysis focuses on how Jun's racial and ethnic positioning is interpreted and represented by others and himself through examining their labeling and categorization practices. I utilized the analysis of two-year ethnography, in-depth discourse analysis of narratives and conversations and mental map analysis. The study shows how Jun and other participants interactionally negotiated their racial and ethnic identities and relationships by strategically positioning each other in an attempt to survive in the environment where they were marginalized. The study illuminates the dynamics and politics of inter-/intraracial and ethnic relations and identities as well as the circulation of a persisting Whiteness ideology in a global context.
