Bosozoku is a Japanese youth subculture based around customised motorcycles. It started among returning World War II veterans, many of whom found the readjustment to civilian life difficult. In the 1960s and '70s, the numbers of these groups swelled with an influx of marginalised and disaffected youths, and stronger ties to various yakuza organisations were also established. This period was marked by fighting between groups, and riots involving large numbers of police were common.
The date of these photographs is not recorded, but three groups who rose to prominence in the 1970s feature heavily: Nina Mona, Specter, and The Black Emperors, who were the subject of Mitsuo Yanagimachi's 1976 documentary Godspeed You! Black Emperor.
