Mane no Tora is the full Japanese title commonly translated as Money Tigers, the format source for Dragon's Den.
The Japanese programme's title is written in Japanese as マネーの虎 and is romanised as Mane no Tora. Literally, the title combines “money” with “tiger,” creating the same animal-investor idea that later became “dragons” in the British version.
The format centres on entrepreneurs presenting business plans to wealthy investors. The investors question the applicants and decide whether to provide funding, generally in exchange for an ownership interest. This core structure was adapted internationally rather than copied as an identical production.
Romanisation can create confusion because Japanese names may appear in several spelling styles. “Mane no Tora” is the standard form used in English-language references to the programme. It should not be confused with the British title Dragon's Den or the American title Shark Tank.
