Money Tigers was the Japanese programme that originated the international format adapted as Britain's Dragon's Den.
The Japanese title is commonly rendered in English as Money Tigers, and the programme established the central structure later used around the world: entrepreneurs present business proposals to wealthy investors, who question the plans and may offer money for an ownership stake.
Britain's Dragon's Den is therefore not an entirely separate invention, although its Dragons, presenters and production style are specific to the British version. The format has been adapted in many countries, with local titles often replacing “dragons” with another powerful animal or business metaphor.
The programme is also sometimes described using the English phrase “Tigers of Money.” That wording reflects an alternate translation of the Japanese title, but Money Tigers is the standard English title generally used in accounts of the format's origin.
