What is Bosozoku?
Japanese motorcycle gang culture from the 1970s-1980s, with a related car styling subculture featuring aggressive aero, exhaust, and paint schemes.
Bosozoku (literally "violent running tribe") originally referred to Japanese motorcycle gangs prominent in the 1970s and 1980s. The motorcycle gangs typically wore distinctive uniforms, modified motorcycles with extended exhaust pipes and stripped-down bodywork, and gathered in nighttime processions through Japanese cities. The culture peaked in the late 1980s with an estimated 40,000+ members nationally.
Bosozoku-style cars emerged in parallel and continued after the original motorcycle gangs declined. The defining elements include extremely long exhaust pipes (often extending several feet beyond the rear bumper), oversized rear wings ("shark fin"-style), front splitters, painted bumpers (typically with bright multi-color schemes), and very low ride height. Common base cars include 1970s and 1980s Japanese sedans (Toyota Cressida, Mazda Cosmo, Nissan Cedric).
The bosozoku car style is largely retired in Japan today (police crackdowns and changing youth culture reduced the practice through the 2000s) but survives as an aesthetic influence in JDM culture. Some imported cars from this era arrive at US events with bosozoku-style modifications. The aesthetic is distinct from modern stance and Japanese tuner culture.

A hashiriya is a Japanese street racer who runs mountain passes or Tokyo's expressways at night. Police class them as an illegal-racing type of bosozoku, mostly solo drivers in cars. Here's how the touge and Wangan scenes work, and the cars that defined them.

The Mid Night Club raced the Wangan from 1987 to 1999, required cars capable of 250 km/h, and made new members serve a year of apprenticeship. When a 1999 crash with a bosozoku gang killed two people and hospitalised eight, they disbanded on the spot.

Shakotan literally means low car, and it's the 1970s Japanese style that every lowered car since has descended from. Deep-dish wheels, a scraped ride height, mild flares, and clean lines. Here's what separates it from bosozoku, kaido racer, and VIP style.
Bosozoku is the most extreme corner of Japanese car culture: cars with exhaust pipes that stab into the sky, body kits that defy aerodynamics, and color schemes that refuse to be ignored. It started with rebel bikers, and it has never been about subtlety.
