Usage notes
The phrase hara ga heru is generally considered somewhat more informal than the synonymous phrase. When in mixed company, the polite perfective form onaka ga sukimashita may be heard more often.

This phenomenon may be somewhat similar to the convention in some English-speaking communities of avoiding direct discussion of body parts. The term hara means “belly, stomach”, whereas the term onaka refers more indirectly to one's “insides”.
