The British TV show Dragons' Den is based on which Japanese reality format?

The British TV show Dragons' Den is based on the Japanese reality format Money Tigers.

Money Tigers was a Japanese programme in which entrepreneurs presented business proposals to wealthy potential investors. Its format was adapted for several countries, with investors deciding whether to offer money in exchange for a stake in a business.

The British version was developed for the BBC and became part of an international franchise. The title changed from the original Japanese name because “dragons” conveys wealth, power and intimidating business personalities in the British format.

The show is sometimes confused with Shark Tank, the United States adaptation of the same broad format. Shark Tank is not the Japanese original; it is a separate national version descended through the international franchise.
