The first race in 1969 was a Formula Libre event and was won by Australian driver Leo Geoghegan driving an ex-Jim Clark Lotus 39-Repco V8.
The 1970 race was won by reigning Formula One World Champion Jackie Stewart driving a Brabham-Ford.
Teams which participated in five rounds in either series were eligible for their respective JAF Grand Prix events.
The ruleset used in the Grand Prix differed from those used in regular-season Formula Nippon and Super GT events.
The JAF Grand Prix title now applies to the season-ending round of the Super Formula Championship held at Suzuka.
