Editing Japanese grammar (section)

===Liberal omission of the subject of a sentence===
The grammatical [[Subject (grammar)|subject]] is [[null-subject language|commonly omitted]] in Japanese, as in

{{fs interlinear|indent=3|lang=ja|transl=Hepburn
|日本 に 行きました
|nihon ni ikimashita
|Japan LOC go-POL-PFV
|went to Japan}}

Subjects are mentioned when a topic is introduced, or in situations where an ambiguity might result from their omission. The preceding example sentence would most likely be uttered in the middle of a discourse, where who it is that "went to Japan" will be clear from what has already been said (or written).
