and the ruling
Liberal Democratic Party promoted legislation, passed on 19 September 2015, despite some public opposition, to allow the
country's military to participate in foreign conflicts, overturning its previous policy of fighting only in self-defense. Since the
Japanese constitution allows the Japanese military to act only in self-defense, the legislation reinterpreted the relevant passages to allow the military to operate overseas for
"collective self-defense" for allies.
The legislation came into effect on 29 March 2016.
Background
Article 9 of the Japanese Constitution
is a clause in the Constitution of Japan outlawing war as a means to settle international disputes involving the state. The Constitution was drafted following the surrender of Japan in World War II. It came into effect on 3 May 1947 during the oc ...
prohibits use of military force internationally. On 15 May 2014, an advisory panel formed by Abe recommended that Article 9 be reinterpreted to allow a broader use of military power. On 1 July, the government announced that it had devised a policy dubbed "collective self defense" to allow it to use armed force to defend its allies.
Abe had originally proposed to give the military even more leeway, but resistance from lawmakers in both parties of the governing coalition led to softening of the language.
With Abe's coalition a majority in both houses of parliament, the language was expected to be passed into law later in the year.
In February 2015, Abe said that he planned to begin work to amend Article 9 after the 2016 parliamentary elections.
Abe cited the

It is called the "Peace and Security Preservation Legislation" by its sponsors.
Debate in the Diet had been scheduled to end in June, but a final vote was later delayed to September.
On 16 July 2015, the House of Representatives passed the legislation, the final version of which allowed the military to provide logistical support to allies overseas as well as armed support in circumstances when inaction would endanger "the lives and survival of the Japanese nation."
The vote was passed on the strength of the majority coalition of LDP and

Public opposition

The legislation was controversial within Japan. According to some polls conducted in July, at the time of the legislation's debate in the House of Representatives, two thirds of the Japanese public opposed the bills.
A protest on 16 July drew an estimated 100,000 people to the

building.
Later protests in September ahead of the House of Councillors vote drew crowds of 10,000 to 30,000.
The Abe governments's approval rating fell below its disapproval rating after the House of Representatives passed the legislation in July 2015 and again after it finally approved it in September. A slight majority of poll respondents in September thought that Japan's deterrent capabilities would not be strengthened by the legislation.
Much opposition to the legislation centered on its alleged questionable constitutionality. Repeated surveys of experts in Japan's constitution showed that more than 90% of those surveyed believed it was unconstitutional,

professor Yasuo Hasebe, in an address to the Diet with two other constitutional scholars, said that it would "considerably damage the legal stability" of Japan.
After its passage, it was expected to be challenged in court, although Japan's legal system has rarely ruled against the government in security matters.
A revision of the Japanese constitution to revise Article 9 would require a national referendum, which perceived current public opposition to Abe and the legislation made it thought to be unlikely to succeed in the short term.
In defense of the bills,
