Neo-institutionalist theory of global 'isomorphism', or so-called World Culture Theory (WCT), has been much debated in comparative education. One notable feature of the debate is that the vast majority of its participants belong to a handful of closely knit comparative education communities. Ironically enough then, a debate that fundamentally concerns the globalisation of education has hardly been 'globalised', with virtually no comparative scholars participating from 'other' comparative education societies. Clearly, there is a need to critically engage with WCT by explicitly drawing on 'other' intellectual traditions of comparative educations. To this aim, I first discuss the critical methodological insights and underlying epistemic standpoint of Japanese comparative education scholars. I then employ their arguments as a starting point for my subsequent post-colonial critique of WCT and the WCT debate. Overall, this study illuminates the hitherto unacknowledged 'epistemic ignorance' of the on-going WCT debate in the English-language, 'paradigmatic' comparative education realm and suggests a way to move beyond this provinciality.
