"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.
Musically, it is a pop ballad with lyrics that intertwine with the film's themes and concepts, highlighting the journey from sadness to strength. Music critics praised "Dear Diary" for the singer's vocal abilities and overall production quality. Commercially, "Dear Diary" was a success in Japan, peaking at number three on the Oricon Singles Chart and number seven on the Japan Hot 100. Despite modest physical sales, the song was certified gold by the Recording Industry Association of Japan (RIAJ) for exceeding 100,000 downloads. Ryouhei Shingu directed a music video with Amuro walking along a beach with various special effects imagery. To promote the single, "Dear Diary" was added to Amuro's Live Style 88 tour setlist and later included in the tour's live release.
