"For the Japanese, Bōsōzoku culture encompasses the lifestyle associated with customized motorcycles and automobiles. When translated literally into English, the phrase roughly amounts to “reckless tribe,” and this latest exploration of Tokyo nightlife from GoPro illustrates that title in gripping fashion. Seeing the act as a form of creative expression, many that are part of this Japanese subculture tour through Tokyo in packs, driving highly customized Lamborghinis, Suzuki Hayabusas, RWB Porsches, and on the extreme end of things Kaido Racers, which are the epitome of Japanese car culture. Watch the GoPro footage shot in 4K quality above to get a feeling for some of the extreme aspects of Japanese nightlife and tuner culture."
