Although Sony Computer Entertainment America is in the midst of relaunching the downed PlayStation Network, government officials will not approve the restart in Japan until Sony provides more information regarding the breach and subsequent preventative measures taken.
According to Kazushige Nobutani, director of the Media and Content Industry department at the Ministry of Economy, Trade and Industry, "As of May 13, Sony was incomplete in exercising measures that they said they will do on the May 1 press conference." He was unable to elaborate on what those measures were.
