Princes of the Yen reveals how post-war Japanese society was transformed to suit the agenda of powerful interest groups, and how citizens were kept entirely in the dark about this. History is now repeating itself around the world. Based on a book by Professor Richard Werner, a visiting researcher at the Bank of Japan during the 90s crash, during which the stock market dropped by 80% and house prices by up to 84%. The film uncovers how the Bank of Japan pumped up and then crashed the Japanese economy, with an aim of inducing change. Today, what happened in Japan 25 years ago is repeating itself in Europe, with an aim of centralizing power in the Eurozone.
