TOKYO - Japan's new Prime Minister Yoshihiko Noda unveiled on Friday a government that will face the task of engineering an economic recovery without blowing a hole in its stretched finances, promising swift fiscal reforms but with an eye on growth.

Noda, 54, the latest of Japan's revolving-door leaders, also said he would seek to balance energy needs with public concerns about safety after a March earthquake and tsunami triggered the world's worst nuclear crisis in 25 years.

Noda's cabinet appointments from various groups in his own party revealed a similar desire to find the middle ground, raising doubts whether the new government caught between conflicting demands can achieve more than its short-lived predecessors.

Noda's government, Japan's sixth in five years, must find funds to rebuild from the March disasters while trying to tame a surging yen, which has gained 5 percent against the dollar in the past two months.

"We can lose no time in reforming public finances. But I'm not putting fiscal reform on top of everything else," Noda told a news conference after being formally appointed. "Achieving a good balance between fiscal reform and economic growth is our top priority."

In a sign he plans to call the economic policy shots himself, Noda picked a relative lightweight lawmaker for the finance minister post.

In fact, in their first news briefings both Noda, who served as finance minister under Prime Minister Naoto Kan, and his successor in the job, 49-year-old Jun Azumi, struck strikingly similar notes on the currency and fiscal policy.

"The economy is recovering from the effects of the earthquake, but close attention should be paid to downside risks to the economy such as from slowdown in the West and the yen's rise," Azumi said, echoing Noda's remarks.

Energy middle road

As in his cabinet appointments and economic priorities, Noda also sought to tread the middle ground on energy policy.

He said he understood the public's safety concerns and admitted it would be hard to build new reactors as planned under a 2010 national energy policy but said he wanted to restart off-line reactors once safety checks were cleared.

Stressing that the alliance with Washington was the core of Tokyo's diplomacy, Noda added: "I'll do my utmost to build up friendly ties with not only China but with other neighbours such as South Korea and Russia."

There were no standout appointments in Noda's cabinet, which - like his earlier picks for party posts - included a mix of lawmakers from various feuding factions. That led some to wonder whether Noda was not putting too much stress on party unity over expertise.

"I don't think this line-up is one that can pull up its socks and respond to the public's hopes," said Katsuhiko Nakamura, executive director at think tank Asian Forum Japan.
