Dear Diary.

About Dear Diary

"Dear Diary" is a song by Japanese singer Namie Amuro. Dimension Point released it as a double A-side single with "Fighter" on October 26, 2016. Furthermore, it serves as the fourth single from Amuro's seventh greatest hits album and final music release, Finally (2017). Both served as themes songs for the 2016 Japanese live-action film Death Note: Light Up the New World, which was inspired by the manga series Death Note. Takahiro Sato, the film's co-producer, approached Amuro about providing theme songs to help her music gain international exposure. "Dear Diary" was written by Matthew Tishler, Felicia Barton, Aaron Benward, and Tiger, and produced by Tishler. Frequent collaborator Emyli provided backing vocals to the track.
