More than 300 municipalities across the country have provided the Defense Agency with personal data on teenage residents that should not have been shared, Defense Agency chief Shigeru Ishiba said Wednesday.

Ishiba told the House of Representatives special committee on private-information protection that 794 cities, towns and villages supplied data at the request of the agency to assist in recruitment activities.

A majority provided only the details that anyone can access under the Basic Resident Register Law -- name, address, date of birth and sex -- of those of recruiting age, mostly between 15 and 18.
