"Woodford, 51, recounted how he had just returned from Hong Kong, having fled Tokyo after a board meeting in which Olympus Chairman Tsuyoshi Kikukawa had fired him. The cause for dismissal, according to Woodford: his insistence that Olympus officials come clean about a series of questionable purchases dating to 2006, totaling $1.6 billion, none of which had been adequately reported in the company’s consolidated financial statements. The deals had been approved by Kikukawa and the Olympus board, yet in several cases the parties receiving the sums were not even clearly identified in Olympus’s books.

Woodford, frustrated by the board’s stonewalling, had hired the accounting firm PricewaterhouseCoopers to conduct an independent audit of the suspicious transactions. For several weeks leading up to his dismissal, he had been calling the board to account for these transactions, and eventually demanded the board’s resignation. Instead, Woodford was purged. And now he was running for his life."
A comment below the story claims: "Based on my own personal experience, I can say with certainty that Mr. Woodford's experience is the rule rather than the exception at most large Japanese companies."

Three years ago, in response to reports that organized crime was investing large sums in public companies, Japan's Securities and Exchange Surveillance Commission compiled an index of more than 50 listed firms with alleged yakuza ties"
