According to Japanese law, a revision of the constitution needs to be initiated with the support of at least two-thirds of the lawmakers in both houses of parliament and must be endorsed by a majority of voters in a referendum.
The revised national referendum law, enacted June 13, will enlarge the voting population and therefore dilutes the number of those who oppose revision of the constitution's Article 9 which formed the nature of the country's war-renouncing supreme law, Xinhua reported.
Abe spared no efforts to make Japan a "normal country" and enable it to exercise the right to collective self-defence, which will allow Japan's self-defence forces to engage in war outside Japan though it violated the spirit of the country's pacifist constitution.
Currently, Abe's administration seeks to reinterpret the constitution to exercise the collective defence rights in the short term, but in the long run seeks to revise the constitution and the revised national referendum law is a critical step toward the long term goal.
Nevertheless, amending the pacifist constitution, which has never been revised since its promulgation in 1946, has drawn criticism both domestically and from abroad.
Abe's efforts to lift the ban on exercising the collective self-defence right by reinterpreting the constitution and expanding arms exports have raised concerns in neighbouring countries such as China and South Korea, which suffered from Japan's wartime aggression.
