"One Love" is the twenty-second single of the Japanese boy band, Arashi. The single was released in two editions: a regular edition containing the karaoke versions of all the songs released in the single, and a limited edition containing only the title track and a DVD of the music video. For the first time in Arashi's discography, a song remix of all the three Hana Yori Dango theme songs was included in the Limited Edition release. The single was later re-issued in commemoration of the success of Hana Yori Dango Final with an insert of two-minute dialogue by Arashi member Jun Matsumoto acting as his Hana Yori Dango character Tsukasa Dōmyōji.
Prior to its release, the working title of the song was "I Love You".[2] The song was first heard on the television program Ōsama no Brunch on April 26, 2008, as background music during the broadcast of the preview of the Hana Yori Dango Final movie. To build anticipation for the upcoming single, the song was also included in the repertoire for the group's Arashi Marks 2008 Dream-A-Liveconcert tour, along with a new song entitled "Green". On May 18, the single was available for pre-order on online music store CDJapan, in which both versions topped the pre-order ranking. The limited edition was also sold out in the online store in two hours. The full song was aired on Matsumoto's radio program Jun Style on May 24, 2008.
