Actress Erika Sawajiri has been chosen for the lead role of "Closed Note," a film adaptation of the story of the same name by Shusuke Shizukui.

"Closed Note" was originally serialized on a mobile phone site between October 2004 and August 2005. The story recorded over one million hits, and it was subsequently published as a book in January 2006. Director Isao Yukisada ("Crying Out Love, In the Center of the World") decided to make a movie after discovering the book in a store.

Sawajiri plays a college student studying education, who is in love with a painter (Yusuke Iseya). When she moves into a new apartment, she discovers a notebook left behind by the previous tenant, an elementary school teacher (Yuko Takeuchi). She opens it, finding that it contains the teacher's diary. As she becomes more engrossed in it, the lives of the two women begin to converge.

Filming began at the end of last month and will continue until late May. The movie is scheduled for release on September 29. Other cast members include Hiromi Nagasaku and Katsuo Nakamura.
