This article focuses on a case study of one Japanese prefectural association and its monthly magazine to reassess the importance of prefectural associations (kenjinkai) beyond the diaspora communities in North America on which Anglophone scholarly focus has remained until now. It also returns an overlooked imperial dimension to Japanese language histories of domestic prefectural associations and discourse over the ‘hometown’. Arguing that the expansive ideas of the hometown, created through the networks of prefectural associations and the pages of their publications, gave rise to ideas of borderless empire and frictionless mobility, this article demonstrates how histories of prefectural associations and magazines like Fukuoka kenjin present a new, regional perspective on both empire and the idea of the hometown in pre-war Japan. Associationalism in and beyond Japan’s empire was not unique, and this article puts the history of kenjinkai in conversation with other such regional settler networks around the globe that were happening at the same time. The article then looks at the transwar continuities and ruptures felt by overseas associations in both North America and among former Japanese colonists, before contextualizing the rise of a ‘third wave’ of domestic migration and hometown discourse in the 1960s.
