The Financial Services Agency (FSA) publicly spanked Mizuho Bank last month by slapping it with a "business improvement order" for letting Japan's organized crime groups use its facilities. At least $2 million in illegal transactions were cited.
Mizuho had been warned about the same thing in 2010 but didn't do anything.
It is quite a scandal. Even the venerable Nikkei Shimbun scolded Mizuho.
