The Defense Agency on Monday said that it and each branch of the Self-Defense Forces have systematically collected data on individuals who made information-disclosure requests, contradicting a statement last week indicating the practice was isolated to the Maritime Self-Defense Force and carried out by one person at his own initiative.

Agency officials also said lists of individuals plus information about them was posted on agency and SDF computer networks and viewed by an unspecified number of officials.

What's more, it is unknown whether any of the private data collected could have been obtained by outsiders.
