No no, the developers have region locked the game. Here's some info about it:
Region-locking
The game is the first PlayStation 3 title to ever be region locked.[5] Atlus has stated that the American release will work in both North and South American regions, with the American and Japanese editions being nearly identical including both English and Japanese text/voice options.[26] However, the online servers are global.[27]
The decision to region lock the PlayStation version of the game has inspired mass fan outrage, with many threatening to boycott the game and company, as they fear it will set a precedent for other companies to region lock future games released on the PlayStation 3. This backlash forced Atlus to issue a press release, in which they state that because both the Japanese and US versions are virtually identical and with their release dates only weeks apart, a region lock was put in place by one of the higher ups in Japan in order to prevent reverse importation (as the price of games in the United States is cheaper than the price in Japan).[15] They further state that this will not be a reflection of a new Atlus policy.[15]
It has, kacta? I thought the release date was still going to be some time during September?
