Money Tigers was the Japanese business programme that directly inspired Dragon's Den's format.
Money Tigers was a Japanese television programme in which entrepreneurs sought investment from a panel of wealthy businesspeople. Its structure supplied the foundation for the international format later adapted in Britain as Dragon's Den.
The British version retained the central dramatic idea: entrepreneurs make a concise business presentation, answer detailed questions and negotiate over money and equity. The British production changed the title and adapted the investor panel and presentation style for its domestic audience.
Money Tigers is easily confused with Dragon's Den itself or with Shark Tank, the American adaptation. Those are different national versions of a wider format. The Japanese title is the specific origin name required here, rather than a description of the British show's investors.
