* Banks fall on credit fears, before U.S. financials earnings

* J. Front Retailing drops, earnings worries weigh (Adds stocks, details)

TOKYO, July 11 (Reuters) - The Nikkei average fell 0.4 percent on Friday, with bank shares hurt by persistent credit fears while investors grew increasingly worried about earnings prospects amid high oil prices and slowing consumption.

J. Front Retailing Co. (3086.T) skidded over 6 percent after the retailer said its operating profit in the March-May quarter fell 14.0 percent. It issued a profit warning for its business year to February 2009, saying consumers are spending less on clothing because of rising food and fuel prices.

Unless the government intervenes, credit fears will persist and financial institutions will keep reporting quarterly losses, said Takahiko Murai, general manager of equities at Nozomi Securities.

"The market is also factoring in the notion right now that corporate earnings forecasts for this year will probably have to be lowered because of high raw materials costs, stemming from high oil prices, and slumping consumption," he said.

The benchmark Nikkei .N225 shed 55.41 points to 13,011.80, while the broader Topix declined 0.6 percent to 1,283.34.

Fujio Ando, senior managing director at Chibagin Asset Management, said bank shares also lost ground after Thursday's gains as investors await earnings results from leading financial firms such as Citigroup Inc (C.N) and Merrill Lynch MER.N next week.

U.S. stocks rose broadly on Thursday after Federal Reserve Chairman Ben Bernanke said the central bank and the government are focused on stabilising the financial system. [.N]

But financial stocks suffered again on concerns the sector may need additional capital to withstand the ongoing credit crisis. Shares of the top two U.S. mortgage finance companies Freddie Mac (FRE.N) and Fannie Mae (FNM.N) were the hardest hit by those fears.
