Mizuho Bank was sued by a former New York-based vice president, who claims he faced discrimination as a non-Japanese worker.

David Kurtanidze filed a complaint Tuesday in state court in Manhattan, naming the third-largest Japanese bank and three of his managers as defendants. Kurtanidze claims that, despite excellent performance and credentials, including prior stints at Morgan Stanley, Goldman Sachs Group, and Credit Suisse, he was denied promotions at Mizuho and treated differently from Japanese staffers.

He is seeking at least $10 million in damages. A spokesperson for Mizuho did not have an immediate comment on the suit.
