Tadashi Yanai: The Iron Fist Behind the Uniqlo Empire

Since then, the top fortune in Japan (valued at $48 billion by Forbes) often references this scene to assert: “The manual is just a set of rules! The most important thing is the customer right in front of you!” This anecdote perfectly encapsulates his character. An ironclad discipline has enabled the emergence of the textile giant Uniqlo, a ubiquitous chain with 2,541 stores from Paris to Shanghai, including New York. Its parent company, Fast Retailing, is projected to generate a profit of 2.5 billion euros on more than 21 billion euros in revenue for 2024-2025. A machine that can jam at the slightest disruption, yet keeps its founder alert at 76 years old.

What is he made of? As a child, he had the roughness of those born with little. He grew up in the 1950s in Ube, a suburb of Hiroshima. His youth was spent amid the smoke of factories and the melodies of American rock, in the baroque carefreeness of post-war Japan.

His father owned a suit shop where the family lived above. Tadashi dreamed of broader horizons and went to study at Waseda University in Tokyo. Then he traveled across America and Europe. He wanted to see this world of dreams for himself.

His method? “The big problem in fashion is inventory management,” summarizes a consultant. “To counter this, there are two schools. The Zara school, with small collections that are frequently renewed; and the Uniqlo school, with timeless pieces that will always sell.” Tadashi Yanai champions the concept of lifewear, basic clothing that can be worn in any situation.

His pieces of fabric must be like tools. Essential and practical. And wearable worldwide. “Toyota, Sony, Honda had one thing in common: they all went to challenge America!” observes author Takashi Sugimoto. “They left the cramped Japan of the post-war era to conquer the world.”

The Uniqlo shareholder models himself after two figures. First, Soichiro Honda, the eponymous founder of the automobile manufacturer, who was free-spirited and rebellious—Tadashi Yanai long had a model of the small HondaJet airplane on his desk. And more importantly, Konosuke Matsushita, founder of the industrial conglomerate Panasonic, the best example of Japan’s ability to mass-produce simple or sophisticated parts indefinitely at an unbeatable cost—thus price. Uniqlo’s HeatTech t-shirts are no different, with their promise of reliable quality at a low cost, akin to a Honda motorbike or a Panasonic screen.

Upstream, this positioning requires production with an unbeatable quality-price ratio, based on extreme—and extremely rewarding—demands. “When Uniqlo’s teams approached us,” recalls Dennis Wong from the Hong Kong-based textile group Crystal, “they asked us to deliver within ten days 17 examples of colorful t-shirts in specific fabrics. Mission impossible. And we did it.” Not only did Crystal profit from the huge orders from Uniqlo, but the supplier also used the acquired know-how to serve other clients.

Downstream, Yanai’s method of absolute control is exercised over his tens of thousands of employees. Everything is decided by him: the most visible garment, the arrangement of colors on the shelves, the text to be printed on the smallest leaflet of the most obscure counter…

Upon hiring, employees are given the famous manual. It is now loaded onto a mobile phone, containing instructions with entomological precision. As confidential as the Coca-Cola formula, the guide must be returned when the employee leaves the company.

According to a store manager, “it’s not so much OCD as it is seeking consistency across the hundreds of Uniqlo stores around the world.” A former executive, less convinced, recounts a scene from a seminar for new recruits: “He asked us: ‘Who has read my manual once? 10 times? 30 times? 50 times? 80 times?’ As the raised hands became fewer, he urged us to read it as many times as possible.”

Tadashi Yanai’s face, dry, with taut features, always seems heavy with an anger ready to burst. “One day, I saw him publicly humiliate a sloppy-dressed IT worker,” recalls a foreign collaborator, who has since left the group. “Tadashi Yanai explained that he must be dressed impeccably since he works for Fast Retailing. I didn’t like that moment: nobody saw this technician, why reproach his attire?” A Japanese employee, still with the group, objects: “Admonishing someone in public is a way to advance the entire company.”

Tadashi Yanai’s story is not a straight line. It is punctuated by bets, successful or failed, recounted in the title of his autobiography: One Victory, Nine Defeats (not translated). Like when he decided, on a whim, to blanket the United Kingdom with 50 Uniqlo stores in the early 2000s. He opened 21, closed 16, now has 20… Or when, in June, his French brands Princesse Tam Tam and Comptoir des Cotonniers were sadly placed in receivership. Or when he appoints global ambassadors (Novak Djokovic, Roger Federer…), without straying from lifewear, which is also an aesthetic. “People think that style is about adding,” whispers the brand’s longtime designer, Naoki Takizawa. “But style, creation, is often about taking away.”

By nature, Tadashi Yanai is just like his products: simple and straightforward. “Basic,” summarizes a French customer outside a Parisian store of the brand, near the Opera. “One day, he had lunch at the embassy with his wife,” recounts a former French ambassador to Tokyo. “They came with… two t-shirts.”

A whole person, with a frankness that stands out in the gray walls of Japanese capitalism. “Trump’s tariffs are absurd,” he thundered during the presentation of the latest semi-annual results, beating American CEOs at their own game regarding the White House’s protectionist agenda.

Yet, beneath the HeatTech t-shirt, this metronomic and frugal heart is capable of almost unexpected generosity. When he awards scholarships to needy foreign students through his Fast Retailing Foundation, for example. “He told us: ‘I have no regrets, the only thing to do is to move forward.’ I think about that often,” shares Vu Xuan Tung Duong, who studies at Tohoku University. Or when he supports Asian University for Women, a university in Chittagong (Bangladesh) that identifies promising young women in the most deprived areas (Yemen, Afghanistan, Palestine…) to offer them education and a springboard for the future.

But it’s not enough. Tadashi Yanai’s obsession with control has discouraged many brilliant executives. For example, Nobuo Domae, now CEO of Muji, a brand driven by the same “basic” philosophy as Uniqlo. As a result, at 76, after repeatedly announcing successors and then postponing his retirement, Tadashi Yanai remains the sole master on board, no longer even pretending that he will one day relinquish the reins.

His successor “will be someone from within,” he simply promises, sidelining his two sons, who nevertheless hold responsibilities within the company. The family fiber is not the strongest within Uniqlo. To spare them, he studies enduring companies that have incorporated family shareholders into governance, like Walmart or Dell.

Unless, in a final reversal, he entrusts one or the other with operational leadership at the moment he must finally let
