This paper addresses a central issue linked to research conducted on an eclectic conglomeration of people connected in various ways to the principal European site of the Japanese new religion of Tenrikyō. Although the center itself is in a Parisian suburb and the majority of its key actors are Japanese, the people connected to this center and its associated social world span beyond the Paris region and include various nationalities, countries of residence, and even religious identities. Moreover, the people connected to this center and the presence of the Tenrikyō religion in Europe are largely one and the same, but not entirely. A question commonly posed to the researcher by "outsiders" is how many Tenrikyō "members" there are in Paris, France, and/or Europe, and if they are Japanese or the nationality of the local country (French, German, etc.) The complexities of answering such questions are the focus of this discussion.
