After the 4th tournament (1967), the year was included in the Japan GP title. Nissan produced the R381, equipped with a Chevrolet 5.5-liter V8 engine, for the 1968 Japan GP. Its unique “aero stabilizers” – the left and right portions of the wing moving independently – earned it the nickname “Monster Bird”. This commemorative car is the victorious No. 20, driven by H. Kitano.
