While the notion of the individual figures prominently in the debate about Christian personhood, the concept of relational selves has shaped the existing literature on Japanese selfhood. I take this seeming divergence between “individual Christian” and “interdependent Japanese” as the point of departure to probe how Japanese‐Brazilian Pentecostal migrants in contemporary Japan understand and experience their sense of self. The article is based on 14 months of fieldwork in Toyota, Japan, which consisted of participant observation, interviews, and surveys among Brazilian and Japanese residents there. The discourses about the category of religion serve as a major source of data to tease out cultural understandings about “the authentic self.” I will argue that Pentecostal personhood does not fit within either the “individual” or the “relational.” The concept of “accompanied self” will then be proposed to accurately capture the kind of self that many migrant converts strive to embody.
