TOKYO (REUTERS) - Japanese Prime Minister Shinzo Abe opened a new session of Parliament on Monday (Jan 22) with familiar promises for economic reform and stronger defence, but steered clear of setting a timeline for his goal of revising the post-war, pacifist Constitution.
The push by the conservative Japanese leader to fulfil his long-held ambition coincides with rising concerns about North Korea's nuclear and missile programmes and China's military assertiveness.
Mr Abe's wariness over setting a timeline reflects the delicate task he faces amending the Constitution's Article 9, which if taken literally, bans a standing military.
Successive governments have interpreted Article 9 to allow a military exclusively for self-defence.
But Mr Abe, aiming to build a lasting legacy as he enters a sixth year as prime minister, wants to add a clause making clear that the armed forces are constitutional.
"I hope each party will submit concrete proposals to Parliament... deepen debate and move forward," Mr Abe said in his speech to Parliament.
"For the sake of our grandchildren, isn't now the time to make progress towards building a new country?"
Amendments require approval by two-thirds of both Houses of Parliament and a majority of voters in a referendum.
Mr Abe's ruling bloc has a two-thirds "super majority" in both chambers - at least until an Upper House election next year - but the outlook for a referendum remains murky.
Mr Abe has proposed an amendment that would retain Article 9's first clause renouncing the right to go to war and a second clause banning a standing military while adding a specific reference to the "Self-Defence Forces" (SDF), as Japan calls its military.
Those in favour of his proposal say it would just codify the status quo. Opponents argue it would make it easier for Japan's military to take part in overseas conflicts.
A Mainichi newspaper survey published on Monday showed 31 per cent agreed with Mr Abe's proposal, while 12 per cent supported a more drastic proposal that would delete the second clause while adding a reference to the SDF.
Twenty-one per cent opposed any change and 27 per cent said they didn't know.
A public vote on the Constitution could end up a referendum on Mr Abe, whose support last year fell sharply due to suspected cronyism scandals.
The Mainichi poll put support for Mr Abe at 44 per cent, though only 37 per cent want to see him win a third term as Liberal Democratic Party leader in September, a win that would put him on track to become Japan's longest-serving premier.
All of which means Mr Abe may decide not to rush and risk rejection.
"Abe is flexible. He might aim for an amendment around 2020," Harukata Takenaka, a professor at the National Graduate Institute for Policy Studies, told reporters recently.
