The Animax Anison Grand Prix (全日本アニソングランプリ Zen-Nihon Anison Guran Puri?) is a Japanese anime song music competition, organized by Animax, in association with Jupiter Telecommunications.
The annual competition is first held across a series of preliminaries in several Japanese cities, with the chosen finalists performing at a final round, which will be broadcast across Japan on Animax, where they will be judged by a panel of celebrity judges, music producers and record company executives, including noted singers Ichirō Mizuki, Mitsuko Horie and Yumi Matsuzawa. The winner of the competition will subsequently perform a theme song to an Animax anime project as their debut and earn a professional contract with Sony Music Japan.
The first Animax All-Japan Anison Grand Prix was held in July 2007, with preliminaries taking place across Tokyo, Osaka, Fukuoka and Sapporo, and was attended by 1792 applicants. The winner of the competition was Shūhei Kita, who subsequently performed "Breakin' Through", the opening theme to the anime series Persona: Trinity Soul as his debut, and earned a professional contract with Sony Music Japan. Kita subsequently also performed "Issei no Sei", the opening theme to the Natsume Yūjin-Chō anime series in 2008.
