A list of candidates to sponsor struggling retail giant Daiei Inc. has been narrowed to three groups. But a final selection by the state-backed corporate bailout agency is far from certain, because the three picked are doing different businesses and there is no decisive factor.

The Industrial Revitalization Corp. of Japan last week picked groups led by supermarket chain Aeon Co., trading house Marubeni Corp. and Kiacon Corp., a fund to revitalize retailers.

Foreign-led consortiums, some of them regarded as powerful candidates, were kicked off the list.
