If established, the NSC will empower the prime minister's office to take the lead in crafting foreign and defence policy by gathering information from various ministries and agencies, according to Japan's Kyodo News.
The prime minister, the chief cabinet secretary, and the foreign and defence ministers will meet twice a month to discuss security issues, it said.
The head office of the council will be set up within the cabinet secretariat to streamline policy-planning through coordination among relevant government ministries and agencies, according to the bill.
