While the PlayStation Network has launched in North America, Europe and other regions, the relaunch of Sony’s services in Japan has been held up by regulators in Japan. According to a Dow Jones report, the PSN will not be relaunched in Japan until Sony provides assurances to the government that it has added additional security to its network services.
"We met with Sony on May 6 and 13, and basically we want two things from them," said Kazushige Nobutani, director of the Media and Content Industry department at the Ministry of Economy, Trade and Industry.
"The first is preventative measures. As of May 13, Sony was incomplete in exercising measures that they said they will do on the May 1 press conference," he said, although he refused to provide exact details of the measures for security reasons.
The second has to do with consumer confidence in Japan and what Sony plans to do about it:
"There were similar cases in the past that were caused by other firms, and we are asking Sony whether their measures are good enough when compared to countermeasures taken in the past," said Nobutani.
Sony relaunched PlayStation Network and Qriocity over the weekend. Separately - though certainly related - Sony Online Entertainment's various MMO's went back online as well.
