Struggling trading house Tomen Corp. said Thursday its earnings for the first half to Sept. 30 plunged with sluggish revenues, and its president said the company is reaching out to the Toyota Motor Corp. group for assistance.

"We have asked the Toyota group for help, and we understand they are considering it," Tomen President Morihiko Tashiro told reporters when the company unveiled the interim financial results.

Tashiro did not go into further detail, but company sources said Tomen has asked Toyota Tsusho Corp., the automaker's trading house unit, to provide support when it implements its new midterm business plan that begins April 1.
