Toyota's financing unit is in talks with a Japanese government-backed bank on possible lending, the automaker said Tuesday, underlining the serious woes facing the car industry amid plunging global sales.

Toyota Motor Corp. said no details had been decided. Kyodo News and NHK TV reported earlier in the day, without identifying sources, that Toyota's auto loan unit, Toyota Financial Services, had asked for a 200 billion yen ($2 billion) government loan.

A spokesman for Toyota Financial Services said the talks with the Japan Bank for International Cooperation were among the various ways being studied to gain funding. The lender does 70 percent of its business in the U.S., where sales have been plunging and credit tightening.

The Japan Bank for International Cooperation, which started helping cash-strapped Japanese businesses last year as the global financial crisis unfolded, said it does not comment on individual company matters. Some companies have been struggling for cash ahead of the fiscal year end of March 31.

The Finance Ministry said Tuesday it will provide an additional $5 billion from its foreign reserves this month to the Japan Bank for International Cooperation, to make sure there is ample cash available for needy businesses. Tokyo has about $1 trillion in foreign reserves.

Finance Minister Kaoru Yosano also said the ministry stands ready to raise the money pool available for lending in yen from 800 billion yen now to 1.2 trillion yen to help companies ride out the deepening global slump.

Toyota, which makes the Camry sedan and the Prius hybrid, had been growing solidly before the U.S. financial crisis hit last year. But now it is expecting a 350 billion yen loss for the fiscal year through March, as plunging global demand and a strengthening yen batter earnings.
