Japan has called for the right to carry out pre-emptive strikes for the first time since World War Two in the wake of North Korean aggression.
Politicians in Japan have argued for the technically pacifist country to have the ability to strike North Korea rather than relying on the US for its defence.
The reclusive state has conducted five nuclear tests and a series of missile launches in defiance of U.N. resolutions.
He added: 'Our country is protected by other countries, but we can't do anything to protect them. This is not acceptable in the international community anymore.'
Gen Nakatani, defense minister until last year and a member of the committee, told the newspaper: 'I believe that we should consider having the capacity to strike.'
Last week Prime Minister Shinzo Abe appeared to give weight to the idea, saying he wanted to 'keep an eye' on developments.
Abe oversaw the acquisition of F-35A stealth fighter jets last year, boosting the country's air defense.
