The English word 'mood' is often translated as 気分 (kibun) or 機嫌 (kigen), but they are not interchangeable. 気分 leans toward physical/emotional feeling, while 機嫌 is about visible mood/attitude. Saying 気分がいい when you mean 'in a good mood' socially can sound like you're talking about your health.
機嫌 (kigen) is about outward mood and temperament, often used when describing someone's disposition. 気分 (kibun) is more about internal feeling, both physical and emotional. To say 'I'm in a good mood' in the sense of being cheerful and pleasant, 機嫌がいい is more natural.
You're in a good mood today, aren't you?
Seems like you're not in a bad mood today.
