It is amazing that no one yet has posted about the Japanese language. Yes, "technically" there is a term for "no" (いいえ). In practice, outside of official documentation, almost no one uses it in daily life. (When you fill official docs, はい==yes, and いいえ==no.) There are so many stupid Japanese language training books that teach you about "いいえ", but you will never hear it in the Real World, except during language trailing dialogs! Most Japanese people will say "違います" (chiigamasu / "it is different") to avoid saying "no" directly.
