Haha (母) means "my mother." This term is used specifically when you are talking about your own mother to someone outside your family. When speaking directly to your mother or when referring to someone else's mother, the more polite form "okāsan" (お母さん) is generally used. Example: 私の母は料理が好きです。(Watashi no haha wa ryōri ga suki desu.) = My mother likes cooking.

自分の母親を、家族以外の人に話す時に使います。例：私の母は料理が好きです。
