Abstract: This article contributes to the emerging area of research in the anthropology of Christianity that focuses on mobility and temporality. It does so by elaborating on the concept of ‘temporal tandem’, which is defined as a process of joint temporalization by which seemingly disparate projects of migration and conversion become interlocked. Pentecostal converts among Brazilians of Japanese descent (Nikkeis) in Japan will serve as a case study to delineate this concept. Temporality figures as a central theme in their stories of migration to the supposed ancestral homeland as well as in their narratives of conversion in Japan. I will illustrate the ways in which conversion addresses common concerns regarding time among the migrant converts, such as ‘putting aside living for the future’. The article concludes with an observation that Nikkeis often experience Pentecostal conversion as a ‘return to the present’, where life is no longer perceived to be suspended.
