lol, no mate, these are totally different, show plates are plates you can get made up that mean nothing and you can get whatever you want put on them.
the ones i have are GENUINE japanese numberplates off a car in japan, and the thing with japanese plates are when you pass your test, you keep the 1 plate for the whole time you drive a car. and u'l probably find these plates are still registered to a car in japan, ive no idea how the seller was aquiring them, perhaps stolen off a car, but for that reason, they are very rare, also if you import a car, the plates go back to the seller in japan, so trying to find a set is very difficult
