Insomnia is the debut album by Japanese singer-songwriter Chihiro Onitsuka, released in March 2001. The album features acoustic-oriented production arranged by Takefumi Haketa, who produced all her studio albums released under the Virgin Tokyo label distributed by Toshiba EMI. It comprises 11 tracks written by Onitsuka, including hit singles "Cage", "Edge", "Memai", and her most well-known and successful song "Gekkō." The lead-off track "Gekkō" was initially used as a theme song for Trick starring Yukie Nakama and Hiroshi Abe, a television drama series aired on Asahi TV in 2000. The song was released as a single in August 2000 and became a smash hit. At the end of the album, a different rendition of the song was included. While "Gekkō" remained on the chart, "Cage" and "Memai" were subsequently released as singles. The lyrics of the latter were acclaimed, winning the 43rd Japan Record Awards for "Best Lyrics" in December 2001. It became the first top-ten hit single for her, peaking at number six on the charts. Before Onitsuka gained popularity through "Gekkō," she had already released a single "Shine" arranged and produced by Nozomu Tsuchiya.
