Michael Oswald's film “Princes of the Yen: Central Banks and the Transformation of the Economy” 『円の支配者』reveals how Japanese society was transformed to suit the agenda and desire of powerful interest groups, and how citizens were kept entirely in the dark about this. Based on the book of the same title by Professor Richard Werner, a visiting researcher at the Bank of Japan during the 90s crash, the stock market dropped by 80% and house prices by up to 84%. The film uncovers the real cause of this extraordinary period in recent Japanese history.
