Itochu Corp. will invest about 2 billion yen for a 0.64 percent stake in a planned holding company for the Seibu Railway group, Itochu officials said Wednesday.

The trading house will cooperate with the group, now undergoing restructuring led by Seibu Railway Co., in such areas as running stores near railway stations and developing computer systems, the officials said.

Seibu Railway shareholders last month approved a proposal to create Seibu Holdings Inc.

U.S. investment fund Cerberus Group will be the top shareholder with a 29.93 percent stake.
