In the States, "pimping out" your vehicle generally involves adding oversized subwoofers, gaudy rims and stupid- looking ground effects kits and spoilers. It's a masculine, masturbatory affair that I never quite understood the appeal of.
In Japan, they like to pimp out vans. It's no less masturbatory, but it's certainly not as masculine. Check out the above van, modified to look like some sort of spaceship from the planet Little Girl. There are more examples in the gallery below, including models dedicated to pop stars and more cartoon characters. Oh, Japan, you're so crazy but I can't help but love you anyway.
Most of these vans have "800 class" registration, which is a designation for camping and oversized vehicles. The "800" appears on the plates next to the prefectural Shaken office name which releases the license tags.
The only requirement is that mechanical parts are a minimum of 9 cm from the ground while bodykits and overhang sizes don't really matter. The kind of people that drive these vans are known as "Yankees," who are usually rebellious and individualistic types that strive to be uniquely different from the masses.
