Hirohisa Fujii has been seen as a champion of fiscal restraint

Earlier reports suggested Mr Fujii's resignation had been accepted.

Mr Fujii, 77, is an experienced backer of fiscal discipline财政纪律. It would be a blow to Mr Hatoyama, who took office in September, if he left, analysts² say.

The prime minister has promised to shift Japan to the left after half a century of conservative dominance优势，统治 by the Liberal Democratic Party (LDP).

Mr Fujii, who is suffering from high blood pressure, was admitted to hospital last week for tests.

He is one of only a few members of the new government with extensive previous experience of administration.

He has been seen as a champion of fiscal restraint抑制，约束, resisting calls from the ruling Democratic Party's (DPJ) coalition³ partners for more spending despite Japan's huge debt, the BBC's Roland Buerk reports from Tokyo.

The prime minister is already getting a reputation for being indecisive犹豫不决的, and is struggling to revive Japan's frail虚弱的，脆弱的 economy and tackle the vast public debt, our correspondent says.

Mr Fujii had told reporters he was exhausted⁵ after weeks of wrangling争吵，争辩 within Japan's governing coalition to finalise the budget.

He was reported to have offered his resignation after a cabinet meeting he had left hospital to attend.

Some reports said the government had accepted Mr Fujii's resignation.

But Mr Hatoyama was quoted on Wednesday as saying that he wanted Mr Fujii to see through干完，干到底 his work on the budget.

"But it is a question of his health, so we also have to think about the opinions of the doctors," he added.
