What is the name of the Dragon's Den investment show format's Japanese original?

The Japanese original of the Dragon's Den investment-show format is Money Tigers.

Money Tigers was the Japanese programme that established the core setup later used by Dragon's Den: entrepreneurs present business ideas to a panel of wealthy investors and seek funding in return for equity. The Japanese title refers to the investors as tigers, while the British adaptation uses dragons.

The format was created for Japanese television before being adapted internationally. The British programme therefore belongs to a wider family of versions rather than being an entirely independent invention.

A common mix-up is to name a different international adaptation instead of the Japanese source programme. Dragon's Den is also sometimes linked loosely to Shark Tank, but Shark Tank is an American adaptation of the same broad format, not the Japanese title.
