Hiroshi Okuda, chairman of the Japan Federation of Employers' Associations (Nikkeiren), said Wednesday the management of Mizuho Financial Group should take responsibility for the computer fiasco afflicting the group's two banks.

"I don't know if that means resignations or pay cuts," Okuda said. "But they should do something to take the blame for inconveniencing so many customers."

Mizuho's computer troubles began just before the April 1 launch of Mizuho Bank and Mizuho Corporate Bank. They were created when Dai-Ichi Kangyo Bank, Fuji Bank and the Industrial Bank of Japan brought three incompatible computer systems to their merger under Mizuho Holdings Inc.
