Cerberus Capital Management LP, the biggest shareholder of Seibu Holdings Inc., should approach Mizuho Financial Group Inc. to help it narrow its differences with the hotel operator, said Hirofumi Gomi, a former candidate for the Seibu board.

The key is to start talks with Seibu's largest private lender and "try to find some middle ground," Gomi said.

Cerberus last month failed in its bid to have Gomi and seven other candidates elected to Seibu's board. The New York-based fund in an emailed response declined comment on whether it was planning to talk to Mizuho.
