Kitagawa was born on August 22, 1986 in Hyōgo Prefecture, Japan. She grew up in Kobe, and lost many friends in the Great Hanshin earthquake in 1995. As a child, she wanted to be a doctor, but by the time she reached high school she was uncertain of what to do in the future. At around this time, she was scouted by a talent agency, and she decided to try the entertainment world. Her parents were initially opposed, but they gave their permission on two conditions: that she give up if she was making no progress within a year, and that she put her studies first and graduate from university. She graduated from Meiji University in Tokyo in March 2009.
