Katsuhiro Otomo's Akira might be a fictional world, but thanks to an incredibly cool new GoPro video in Tokyo, it may not be that far from the truth. 

The roughly-nine minute clip is part of the "HERO4: The Adventure of Life in 4K" series, and shows the wild biker and car culture in Tokyo. The footage features futuristic looking souped-up cars like Lamborghinis and RWB Porsches and shows them ripping through the streets of Japan.

The documentary style clip gives a vivid insight into the underground world of Tokyo car and biker culture, and also makes you want to own one of these incredible cars.
