This is well documented at this point, but just be warned that while you can play the imported card on any region PSN account, if you're not on a Japanese PSN account you will not be able to make use of the game's DLC or data sharing functions. I believe the process to switch accounts is outlined in the first post of the monthly Vita PSN thread, but in a nutshell it requires a system reset and you have to either wipe your memory card (after having made a backup before starting the process) or use a second one.
Then I suppose a second card is needed for miku DLC and PSO2. Is 8 gigs enough for the two of them? Also what's the best way to buy points for the Japanese PSN?
