The velar nasal in Tokyo Japanese: A case of diffusion from above

The present study is an attempt to investigate Japanese as it is spoken in Tokyo within the variationist framework, focusing on the variable (ng). The results of earlier research and observation have shown that this variable has been in the process of change. Speakers at younger age levels favor the newer variant [g], while those at older age levels favor the older variant [ŋ]. Results of quantitative analyses of the data obtained from sociolinguistic interviews with 62 native speakers of Tokyo Japanese allow us to establish the case under investigation as one of diffusion from above. The findings of the present investigation add to the body of research conducted within the variationist framework; they confirm the existence of inherent variation and orderly heterogeneity.
