Being the oldest of the 1st generation of Morning Musume—she was 24 at the time of formation and nearly 28 upon leaving the group—Nakazawa held the role of the group's leader until her graduation on April 15, 2001. She has cited her reasons for leaving as being her age (she was 14 years older than the youngest member of the troupe, then 13-year-old Ai Kago, at the time of her departure) and her desire to pursue other things by the time she was 30.
