via BBCJapan's Prime Minister Shinzo Abe has called for a new interpretation of the constitution, which could pave the way for the military to fight overseas.
His call came hours after a panel of advisers - picked by Mr Abe - released a report recommending changes to defence laws. Japan's constitution bans acts of war and "the threat or use of force" to settle international disputes.China has criticised the move, accusing Japan of taking "negative actions".
Under Article 9 of its post-war pacifist constitution, Japan is blocked from the use of force to resolve conflicts except in the case of self-defence. But Mr Abe has indicated he wants to re-examine the role of Japan's military to meet the changing security environment in the Asia-Pacific region.
The government has long held the view that under international law, it has the right to collective self-defence - which is the right to use arms in stopping attacks on friendly countries. But it also believes that it cannot exercise that right because the constitution sets a limit on the use of armed strength.
The panel's report on Thursday called for this position to be dropped and argued that Japan should be allowed to engage in collective self-defence, said state news agency Kyodo.
They also suggested a set of conditions be imposed to ensure this power would not be abused.They were making these recommendations in light of challenges posed by China and North Korea, they added. Mr Abe agreed that a review was needed on the current interpretation of the constitution.
"It is necessary to deepen co-operation with other countries so that we can seamlessly... cope with any situation to protect our peaceful lives." But he also pledged that Japan would not again become "a country that wages war", report agencies. The changes, although modest, are extremely controversial, says the BBC's Rupert Wingfield-Hayes in Tokyo, and Mr Abe is certain to face stiff opposition.
The move will likely please the US, with whom Japan has a long-standing security treaty, however. But it drew immediate criticism from Beijing.
Chinese Foreign Ministry spokesman Hua Chunying said on Thursday that Abe's government was taking "negative actions" that raised concerns about Japan's true motives, according to agencies.
And about the report specifically:
via NHKA panel of Japanese experts has submitted a report that calls for changing the interpretation of the Constitution to enable Japan to use the right of collective self-defense.
The panel was set up by Prime Minister Shinzo Abe. The panel chief, former vice foreign minister Shunji Yanai, handed the report to Abe on Thursday.
The traditional interpretation held by previous governments is that the Constitution does not enable Japan to exercise its right to collective self-defense.
The right would allow it to use force to defend other countries that have close relations with Japan if they come under attack.
The panel report says the security environment surrounding Japan has become ever more severe. It points to North Korea's nuclear and missile development and China's increased maritime activities.
The report says adequate responses can no longer be taken under the current constitutional interpretation to maintain the peace and security of Japan, and to realize regional and global peace and stability. It says the security of Japan today cannot be ensured through only the right of individual self-defense. The report says it should be interpreted that the exercise of the right of collective self-defense is included in "the minimum extent necessary" for self-defense permitted under the Constitution.
The report cites 6 requirements for the use of the right, such as when a foreign country that is in a close relationship with Japan comes under attack and if such a situation has the potential to significantly affect Japan's security. Japan must also obtain an explicit request or consent from the country under attack.
The report gives examples of activities that could be made possible only after the use of collective self-defense is enabled. Among them are defending US vessels and inspecting suspicious ships in case of a contingency near Japan.
Abe will hold a news conference later on Thursday to lay out his government's basic direction for proceeding with the deliberations.
The prime minister is expected to ask the governing coalition of the Liberal Democratic Party and the New Komeito party to speed up discussions on the matter.
Saw his press conference on TV earlier. The situations being shown were kind of corny. A random US warship getting attacked by China and Japan unable to help. I don't know if they actually think this is a legitimate / imminent threat or whatever.
Also pretty divisive, obviously. There were some pretty sizable protests in Tokyo a couple of days ago.
Better safe than sorry? ┐(´ー`┌
