Restored operations are mainly limited to online gaming, chat and music streaming services. Sony said it aimed to fully restore the PlayStation Network by the end of May.
Sony also began Sunday a phased restoration of its Qriocity movie and music services which share the PlayStation Network's server, said Sony Computer Entertainment Inc. spokesman Satoshi Fukuoka.
Limited services will also resume in Australia, Canada, New Zealand and the Middle East, and Sony said it will start restoring the service for users in Asia soon.
Sony's PlayStation network is a system that links gamers worldwide in live play. Sony shut it down on April 20 after discovering a hacker attack.
Sony said personal data, including credit card numbers, may have been stolen. But the company said Sunday it had not received any reports of the stolen information being used illegally.
