For the 1969 Japanese Grand Prix, Nissan was facing more competition than ever before. The Porsche factory decided to bring one of their new 917s to the event with Jo Siffert and David Piper. Various other Porsches were also part of the field. Toyota had been continuing in development of their 7, while Isuzu entered for the first time with their R7-Chevrolets.
