Money Tigers is the Japanese television show that provided the original format for the UK series Dragon's Den.
The concept places entrepreneurs before a panel of wealthy businesspeople who can offer investment in exchange for a share of the company. The pitch structure, negotiation and possibility of leaving without a deal are central features carried into the British adaptation.
The format travelled internationally under different names. In the United States it became Shark Tank, while many countries retained versions of the Dragon's Den title. These programmes share the basic premise but use local investors, currencies, broadcasters and production styles.
Money Tigers is sometimes confused with Shark Tank because both are widely known English-language adaptations. Shark Tank is not the source title for the British programme; the UK series belongs to the format lineage that began with Japan’s Money Tigers.
