Few TV shows have managed to influence the world of entertainment and entrepreneurship as much as The Tigers of Money or in Japanese Manē no Tora (マネーの虎). Long before Shark Tank became a global phenomenon, it was this Japanese reality show that attracted millions of viewers, combining suspense, business, and a dose of human drama. In this article, we will dive deep into the “cradle” of the format that changed the way entrepreneurship is presented on television.

What was Manē no Tora?
First broadcast in October 2001, by Nippon Television (日本テレビ), the show revolutionized the game show genre in Japan. Unlike traditional entertainment formats that focused on physical challenges or quizzes, Manē no Tora bet on something unprecedented: putting ordinary entrepreneurs face to face with powerful investors, in search of real financial support.
The name — literally “The Money Tiger” — evoked strength and predatory instinct, characteristics associated with both the business world and the investors themselves, known as “Toras” (Tigers). The slogan was direct and provocative: “No Challenge, No Success” — an invitation for participants to risk everything for their dreams.
The show aired until March 2004, totaling over 100 episodes, and left a deep mark on Japanese culture, serving as inspiration for adaptations in various countries, including the popular Shark Tank.

How did the format work?
The operation was simple but loaded with tension: each episode featured two to three entrepreneurs, who had to present their business ideas, products, or services to a fixed panel of investors. These investors, successful businesspeople, had complete freedom to accept or reject the proposal. There was no obligation to finance.
To receive the investment, the entrepreneur needed to convince the tigers to offer the requested amount, either fully or partially. When the investors were interested, they could also suggest changes to the business model or propose additional conditions — which often turned the negotiation into a true verbal battle.
Unlike many reality shows, where the focus is pure entertainment, Manē no Tora placed the commercial viability of the proposals at the center stage. And this created an environment where hope, risk, and pragmatism intersected all the time.
Who were the main “Tigers”?
One of the differentiators of Manē no Tora was precisely the choice of its investors: all real figures from the Japanese corporate world, many of them eccentric, others discreet, but invariably successful.
Among the most iconic, we highlight:
- Shinji Hattori: owner of a chain of English schools, known for his aggressive negotiation style.
- Yoshihiro Terada: food industry entrepreneur, famous for his direct and ruthless critiques.
- Hiroyuki Ariyoshi: more reserved investor, who often surprised with unexpected decisions.
- Ritsuko Nagao: one of the few women on the panel, respected for her attentive view of the social aspects of the projects.
Each of them represented a distinct facet of the business world in Japan, and their interactions with the candidates were an essential part of the program’s appeal.

Memorable pitches and unusual inventions
Throughout its seasons, The Tigers of Money received hundreds of proposals, some as creative as they were unfeasible, others surprisingly visionary.
Among the most talked-about pitches:
The robot restaurant: an entrepreneur presented the idea of opening a fully automated restaurant, where orders would be made via tablets and dishes delivered by robotic arms. Although it seemed too futuristic for the time, the project caught attention for its boldness but was ultimately rejected by most investors, who deemed the cost unfeasible.
The instant ramen machine: an inventor proposed a vending machine capable of preparing and serving fresh ramen in less than two minutes. The idea received praise for its practicality and feasibility and received partial investment, with suggested adjustments to make the equipment more compact.
A manners school for teenagers: unusual but quite relevant, this proposal sought to offer extracurricular courses for young people to learn good manners and social skills. While some tigers found the idea outdated, others saw a promising niche and decided to invest.
One of the biggest successes of the program was the proposal for a chain of organic coffee shops, which after receiving the requested funding, managed to expand to several Japanese cities and remains active to this day.
The cultural impact and legacy of the program
More than just a show, Manē no Tora helped popularize the concept of entrepreneurship in Japan. Before it, the Japanese business environment was often associated with large corporations and careers within the traditional model of lifetime employment. The program, by putting individual entrepreneurs in the spotlight, helped open space for a new vision: that of the “self-made man”, or the one who builds his own path.
The format also innovated by exposing the vulnerability of the participants: many of them presented their ideas not just as a business, but as a personal dream, revealing fears, frustrations, and hopes in front of the cameras. This human aspect, combined with the rawness of the tigers’ responses, created an engaging narrative that transcended mere entertainment.

Exporting the format: from Japan to the world
The success of Manē no Tora quickly drew international attention. Its formula was adapted for “Dragons’ Den” in the United Kingdom and later for “Shark Tank” in the United States and various other countries.
Interestingly, while Japan associated its investors with tigers, in the UK they became dragons, and in the US, sharks. Each adaptation incorporated specific cultural traits, but the essence remained the same: entrepreneurs seeking investment and investors deciding who deserves support.
Despite its global influence, few know that the heart of Shark Tank beats with a Japanese accent — something that still impresses the most attentive fans of the franchise.
Why did Manē no Tora end?
Although the program was a success, its airing was ended in 2004. There are various speculations about the reasons: natural wear of the format, difficulty in finding sufficiently prepared entrepreneurs, and even pressures from the advertising market itself, which did not always look favorably on the exposure of failed businesses in prime time.
Still, its short trajectory left deep marks on Japanese and global television. Manē no Tora may have gone off the air, but its influence remains alive. It opened doors, transformed careers, and, above all, proved that good ideas, when well presented, can find those who believe in them.
Whether in the form of a tiger, dragon, or shark, the predatory investor is now a consolidated presence on global TV thanks to the boldness of a Japanese program that, over two decades ago, decided to bet on the unlikely combination of business and entertainment.
