Japan, more specifically, the Harajuku district of Tokyo, has a number of … very aesthetically bold subcultures, which certain people take extremely seriously.
One of which is basically exagerated 1950s American Rockabilly.

A good number of these guys are in actual Rockabilly bands.
I dunno if this guy’s PS1 blocky haircut really fits into an existing subculture, or if it is a joke off of this subculture… or if it is totally unrelated to all that…
But there actually are a good number of very dedicated aesthetic subcultures in the Harajuku district, Rockabilly is one… the ‘gothic lolita’ style almost certainly came out of Harajuku… there are many other niche identity/aesthetic/lifestyle cliques.
That is what I was referring to, not just… psycho/rockabilly generally around the world.
That… the wild motorcycles… may be a subgroup of the rockabilly group, or another group?
I am not sure lol.
