Therefore, the series needed to be authorized directly by FIA and was not able to be named Japanese Championship because the series had to be parted from Japan Automobile Federation (JAF), the Authority Sport Nationale (ASN) of Japan.

On December 10, 2004, while the series had been mainly focused on Japanese domestic teams, sponsors and fans, with an ever-rising international fan following and TV coverage shown all over the world it was announced that JGTC would now be called Super GT with the goals of "challenge to the world", "challenge from the world", and "challenge to entertainment".
