TOKYO (REUTERS) - Support for Japanese Prime Minister Shinzo Abe slid in opinion polls after his ruling coalition steamrolled through parliament a tough secrecy act that critics fear could muzzle media and allow officials to hide misdeeds.
Shrinking support could push Abe, who took power last year pledging to revive a stagnant economy, to softpedal his security policies until next year's budget is enacted and a sales tax hike from April is safely navigated, some analysts said.
Support for Abe's government fell 13.9 points to 54.6 per cent in a poll by broadcaster JNN, the lowest since he took office, although backing for the main opposition Democratic Party rose just 0.9 point to 6.8 per cent and was dwarfed by the 30.3 per cent who backed Abe's ruling Liberal Democratic Party.
"Abe's support tends to drop when he shows his 'Abe colour'," said Nihon University professor Tomoaki Iwai. "But he knows that. I think he will focus on the economy for a while."
A survey by news agency Kyodo showed support for Abe's cabinet fell 10.3 points to 47.6 per cent, its first drop below 50 per cent in a Kyodo poll since Abe began his rare second term.
His first 2006-2007 term ended when he quit after a year marked by a big election loss, deadlock in parliament and ill health.
About 82 per cent of the respondents to the Kyodo poll, conducted on Sunday and Monday, wanted the secrets act - which some critics have likened to Japan's harsh authoritarian regime before and during World War Two - to be revised or abolished.
Abe says the secrecy act is vital to convince allies such as the United States to share intelligence as he sets up a US-style National Security Council to streamline foreign and security policy.
Top government spokesman Yoshihide Suga told reporters the drop was not unexpected.
He attributed the decline to public misunderstanding of the law's content and said the government would continue to explain it to gain support.
The upper house of Japan's parliament late on Friday approved the state secrets act, which toughens penalties for leaks and broadens the definition of official secrets, despite protests by thousands of demonstrators near parliament and criticism from a broad swathe of media and intellectuals.
The law provides for public servants or others with access to state secrets to be jailed for up to 10 years for leaking them.
Journalists and others in the private sector convicted of encouraging such leaks could get up to five years for using "grossly inappropriate" means to solicit the information.
Top officials in all ministries will be able to designate special state secrets in four categories - defence, diplomacy, counter-terrorism and counter espionage - that can be kept secret for up to 60 years, and in some cases, longer.
A weekend survey by the Asahi newspaper also showed Abe's support rate falling, by three points, to 46 per cent.
Past governments have stretched the limits of Japan's US-drafted pacifist constitution but Abe wants to go further, including by easing a self-imposed ban on exercising the right to collective self-defence, or aiding an ally under attack.
