Daiei Inc.'s three main creditor banks reaffirmed their plan Monday to seek help from the Industrial Revitalization Corp. of Japan to rescue the embattled retailer, bank officials said.

UFJ Bank, Mizuho Corporate Bank and Sumitomo Mitsui Banking Corp. will probably convey the plan to Daiei this week, the officials said.

The lenders are already informally discussing ways to support Daiei with other major supermarket chain operators such as industry leader Aeon Co. and Ito-Yokado Co., they said.
