The Fasu language of New Guinea is not closely related to other languages, but forms a possible branch of the Trans–New Guinea (TNG) family. Wurm and Hattori (1981) considered its three principal dialects, Fasu, Some, and Namumi, to be three languages, which they called the West Kutubuan family, but Ethnologue (2009) considers it a single language. It is not close to the two East Kutubuan languages.

Although Fasu has proto-TNG vocabulary, Malcolm Ross considers its traditional inclusion in TNG to be somewhat questionable.
