Both races were held at the Tanaka International Aida circuit (now Okayama International Circuit), a slow, twisty 3.7-kilometre (2.3-mile) track deep in the countryside in Aida (near Kobe), Japan.
Ambas carreiras celebráronse no Circuíto Internacional Tanaka (agora Circuíto Internacional de Okayama), un trazado lento e sinuoso de 3´703 km. en Aida (preto de Kōbe), Xapón.
