Sony announced resumption of PlayStation Network service in Japan for this week. In what seems to be one of the company’s most serious blunders, Sony will complete global restoration of PSN on July 6.

Apparently, PlayStation Store and Qriocity services will be available in Japan as of July 6. While the company took care of other regions of the world, Japanese authorities have been much stricter and demanded assurances of security.

It is said that the company lost $170 million in the process. It includes investigation, rebuilding of security systems, identity theft monitoring and compensating users with free games.
