Tobati, or Yotafa, is an Austronesian language spoken in Jayapura Bay in Papua province, Indonesia. It was once thought to be a Papuan language. Notably, Tobati displays a very rare object–subject–verb word order.

/f/ also shows allophony as [p]. However, it does not behave as a stop (see below).

Tobati has a five-vowel system of /a e i o u/, realized as /a ɛ i ɔ ʊ/ in closed syllables.

Tobati permits three consonants in the onset, and at most a single consonant or a nasal-stop cluster in the coda.

Nasal-stop clusters only permit a nasal and a stop of the same place of articulation. For the /nd/ sequence, /n/ becomes dental [n̪]. Neither the bilabial, consisting of /b/ and the /f/ allophone [p], nor palatal nasal-stop clusters distinguish voice (i.e. they are [pm~bm] and [cɲ~d͡ʒɲ] respectively). The /Nk/ sequence voices to [ŋg].
