The government plans to ask the Diet for approval this fall to revise more than 10 laws to enable Japan to exercise the right to collective self-defense, a government source said.

Prime Minister Shinzo Abe's Cabinet plans to focus on amending existing legislation, rather than attempting to draft new overarching laws spelling out the basic principles of the major change he is seeking in national security policy, the source said Saturday.

Abe is expected to make a final decision on whether to lift the self-imposed ban on collective self-defense before the Diet closes for the summer on June 22.
