Hey, can I trade in a Japanese White PSP to a Gamestop?

you could just go there and ask...

 but otherwise i'd doubt that they would accept it

ya just go there but some how I REALLLLLLLYYY doubt it

You would be better off on craigslist or Ebay.

Gamestop won't take the games, but I know Play N Trades will. I have seen a few PNT's with Japanese PSP games.

I think you can trade in the system but not the games.
