Japan's pension system has been hacked and over a million cases of personal data leaked, Japanese media said on Monday.

The data from the Japan Pension System's computers included names and identification numbers, said public broadcaster NHK.

The pension system and the welfare ministry would brief reporters shortly, the reports said.
