Fifty years ago, Lamborghini exported its first model to Japan, the 400 GT, so naturally this is an occasion to celebrate. In fact, Lamborghini is so thrilled with its Japanese market base that, upon the reveal of the Aventador S Roadster in Tokyo last week, it also showed off a new special edition of the car, inspired by the five natural elements in Japanese culture: water, earth, fire, wind and sky. Called the Aventador S Roadster 50th Anniversary Japan, each of the five is a one-off but only the "water" version was displayed during Lamborghini Day in Tokyo.

It features special shading effects where the blue paint tends to black, a result of 170 hours of labor by ten specialists in the paint house. The interior is comprised of Nero Ade black leather and Nero Cosmus black Alcantara.

"On the occasion of this important anniversary for our brand in Japan, I wish to thank our Japanese customers for their support over the years and their strong bond with our marque," said Stefano Domenicali, CEO of Lamborghini. "Thanks to them, Japan has now become our second most important market worldwide in terms of cars sold." Lamborghini Day wasn't only a reveal, but also the second time the Lamborghini Day Concours d'Elegance Tokyo event was held. Japanese owners brought such icons like the Miura, Countach, Diablo, and LM002. There was also a jury that decided a "Best in Show," awarded to an orange 1976 Countach LP400. And, of course, there was a parade of 80 Lamborghinis that wound through downtown Tokyo.
