DiVA is a sub-unit of the all-female Japanese pop group AKB48.
The formation of DiVA was announced to Sayaka Akimoto and Sae Miyazawa on January 10, 2011, and disclosed to public by the all DiVA members at AKB48 Theater on February 27, 2011. The initial four-member unit consisted of Sayaka Akimoto, Sae Miyazawa, Ayaka Umeda and Yuka Masuda. The concept of the unit is "The first-ever Dance & Vocal unit from AKB48". They originally scheduled to release their debut single on April 27, 2011. But on April 1, it was announced that the release date has postponed to May 18 due to the aftermath of the 2011 Tōhoku earthquake and tsunami. The A-side song, "Tsuki no Ura gawa" (月の裏側 Reverse side of the Moon?), is written by Akimoto, as well as some B-side songs including AKB48 Team-K's theater-performed song "Blue Rose", and one of the songs recorded on Type-B CD, "Information" (インフォメーション?), is written by Tetsuya Komuro.
It was announced on the official DiVA blog that Akimoto Sayaka will continue her activities in DiVA even after her graduation from AKB48 on August 22, 2013 at AKB48's Tokyo Dome Concert while her last stage performance is on August 28.
