€2.25bn needed to pay off debts
Japan Airlines (JAL) is seeking €4.5bn (Y600bn) in aid under its new re-structuring plan.
About half the sum will be used to pay off debts.
The struggling carrier will also make 2,200 more staff redundant, above the 6,800 announced last month.
Most of the loans would be guaranteed by the Japanese government which would also provide part of the new capital, Reuters said.
The carrier, the largest in Asia in terms of revenue, is putting together a new re-structuring plan after the country's new Democratic Party government said its existing one was not good enough.
On top of the original 6,800 redundancies, the first plan also included the axing of 50 long haul routes and a freeze on pay and pensions.
The new plan, which has not been officially announced, involves the extra job losses as well as the possibility that the airline's president Haruka Nishimatsu might stand down, Reuters said.
JAL's main creditor is the state-owned Development Bank of Japan with others including the Mizuho Corporate Bank, the Bank of Tokyo-Mitsubishi UFJ and Sumitomo Mitsui Banking Corporation.
The country's new transport minister Seiji Maehara met executives from JAL earlier this month, among them Mr Nishimatsu.
Following the meeting, at which the airline asked for public aid, Mr Maehara set up a special group to put a rescue plan together.
He told a press conference in Tokyo that he felt the group could come up with a "fundamental solution".
JAL received a loan of $1.1bn earlier this year to help it with its deficit from the previous Japanese government.
It has also been in talks - now on hold - with two US carriers, Delta Air Lines and American Airlines, a fellow member of the oneworld alliance about a possible cash injection of $300m.
JAL lost $692m last year and announced a $1bn loss for the quarter to June this year.
It is heading for a deficit of $700m for the financial year ending next March.
