Born in 1982, Chihiro Ito started working in movie production in 2000, as staff in the art department. A pivotal event in her career was when she met film director Isao Yukisada. He suggested to her that she write a screenplay for his next film "Seventh Anniversary" (2003), which became Ito's professional screenplay debut. The following year, she wrote the screenplay for "Crying Out Love, in the Center of the World" (2004) with Yukisada and Yuji Sakamoto. The movie was a phenomenal success which brought her increased recognition.
In 2005, Chihiro Ito received a letter from Producer Tomohiko Ishii. The letter asked if she would meet director Mamoru Oshii, who saw "Snowy Love Fall in Spring" and was impressed with the screenplay, and asked if she would write the adaptation for "The Sky Crawlers". She then read Hiroshi Mori's "The Sky Crawlers" novels and became interested in the project. After meeting Oshii at a ryokan named Wakana in Tokyo, she signed on for her first animation screenplay.
