The restart this time doesn't include Asia because Tokyo-based Sony is still in talks with Japan's industry ministry, which is asking for more detailed explanation on how Sony's online service works and what security measures the company is implementing, according to a person familiar with the situation. Because Japan doesn't have a local equivalent of Debix, which has services that cover thefts and misuses of not only credit cards but also other personal information, Sony and the ministry are still figuring out the best way to protect Japanese customers, the person said.

As the vast majority of PlayStation Network users in Asia are in Japan, the service in the region won't resume until the Japanese service is ready to relaunch. And Sony can't restart the service in Japan unless the Ministry of Economy, Trade and Industry gives the green light.
