How a Loom Patent Funded the World's Biggest Car Company

Toyota did not start in a garage. It started in a textile factory, and the story of how it became the largest automaker on earth is stranger and more interesting than most people know.

Most great company origin stories begin with a visionary and a product. Toyota begins with a loom.

In 1924, Sakichi Toyoda, a Japanese inventor with a genius for mechanical engineering, built the Toyoda Model G Automatic Loom, a machine that could stop itself automatically when a thread broke. The principle behind it, known as jidoka, sounds simple. It is not. It meant that quality control was built into the machine itself, rather than relying on a human operator to catch every problem. That idea that a system should detect its own errors and stop before they compound would eventually become one of the foundational principles of the Toyota Production System, one of the most influential manufacturing philosophies ever developed.

In 1929, Sakichi sold the patent for that loom to the British company Platt Brothers. The sale generated the starting capital for an entirely new venture. His son, Kiichiro Toyoda, took that money and began building cars.

From Trucks to Toyopet: The Early Years

The Automobile Division of Toyoda Automatic Loom Works was established on 1 September 1933. By August 1935, the company had produced its first truck, the G1, modelled partly on a period Ford truck and priced ¥200 cheaper. By April 1936, Toyoda's first passenger car, the Model AA, was rolling off the production line at ¥3,350 again, ¥400 cheaper than equivalent Ford or GM offerings.

In September 1936, the company ran a public competition to design a new logo. Of 27,000 entries submitted, the winning design used the three Japanese katakana letters for "Toyoda" arranged in a circle. But Rizaburo Toyoda, who had married into the family, preferred "Toyota" for several reasons. It took eight brush strokes to write in Japanese, and eight is a lucky number. The voiceless consonant at the end sounded cleaner and clearer than the voiced sound in "Toyoda." And perhaps most practically: "Toyoda" literally means "fertile rice paddies," which was not the association a modern industrial company wanted attached to its name.

Toyota Motor Company was incorporated on 28 August 1937. The loom business had become a car company. Kiichiro served as vice-president; his brother-in-law, Rizaburo, as the first president.

The company's early years were shaped by forces largely outside its control. World War II pushed Toyota almost exclusively into military truck production. Its plants were bombed by Allied forces in August 1945. Post-war occupation authorities banned passenger car production entirely. Toyota survived by building civilian trucks and repairing US military vehicles until a Bank of Japan bailout in 1949, triggered by a financial crisis caused by a government stabilisation programme, forced significant restructuring.

The rescue that actually stabilised the company came from an unexpected source: the Korean War. The US Army placed an order for 1,000 trucks in the early 1950s, and the resulting cash flow helped Toyota rebuild.

The Trip That Changed Everything

In 1950, a group of Toyota executives, including Kiichiro's cousin Eiji Toyoda, who would lead the company for the next two decades, travelled to the United States to study American manufacturing. They spent time at Ford and observed operations at dozens of US manufacturers.

What they saw was impressive. What they learned, though, was not simply how to replicate what they saw, but how to improve upon it. The knowledge they brought back, combined with the principles inherited from the loom business, gave rise to The Toyota Way and the Toyota Production System: a lean manufacturing philosophy built around eliminating waste, empowering workers to stop production when problems arise, and relentlessly pursuing improvement in every process.

These were not just management buzzwords. They were operational realities that produced vehicles of consistently higher quality, at lower cost, with fewer defects, than virtually any competitor could match. The Toyota Production System would go on to be studied, imitated, and taught in business schools around the world. It is arguably as significant as any car Toyota ever built.

The Corolla, the Crown, and the American Market

Toyota's first attempt to crack the American market did not go well.

The Toyopet Crown was introduced in the United States in 1958. It had been designed for the muddy, slow, unpaved roads of Japan, engineered for endurance rather than high-speed performance. American buyers, driving on good roads at highway speeds, found it overpriced and underpowered. Exports were suspended within a few years.

Toyota learned from the failure and returned with purpose. The Toyota Corona, redesigned specifically for the American market with a more powerful engine, found success in 1965. US sales tripled in a year. By 1967, Toyota was the third-best-selling import brand in the United States.

Then came the Corolla.

Introduced in the late 1960s to capitalise on Japan's rapidly growing middle class and its newly improved road infrastructure, the Corolla was affordable, reliable, and practical in a way that resonated with ordinary drivers everywhere. It became the world's best-selling automobile of all time, a record it still holds. No single car has been bought by more people, in more countries, over more decades, than the Toyota Corolla.

Building a Global Empire

The scale of Toyota's subsequent expansion is difficult to fully comprehend without the numbers.

The company established its first production facility outside Japan in Brazil in 1958. It entered Saudi Arabia with Land Cruisers in 1955, Yemen in 1956, the Philippines and Indonesia in the early 1970s. It struck deals to manufacture locally in markets that imposed high tariffs on imported vehicles, including a creative arrangement in the United States involving truck beds and the infamous 25% "chicken tax" on imported light trucks, which Toyota sidestepped by importing chassis cabs and attaching the beds domestically.

Today, Toyota operates manufacturing facilities across dozens of countries, holds significant stakes in Subaru, Mazda, Suzuki, Isuzu, Yamaha Motor, and Panasonic, and produces vehicles under five brands: Toyota, Lexus, Daihatsu, Hino, and Century. Its subsidiaries include Toyota Financial Services, Woven by Toyota (its technology and software division), and Prime Planet Energy & Solutions, its battery manufacturing joint venture. In 2024, the company generated revenue of approximately $411 billion and net income of $45 billion. Its total production reached 300 million vehicles by September 2023, a cumulative figure that spans nearly a century of manufacturing.

It was the first automaker in history to produce more than 10 million vehicles in a single year, achieving that milestone in 2012 when it also reported the production of its 200 millionth vehicle. As of 2025, its market capitalisation stands at approximately $260 billion, making it one of the most valuable automotive companies in the world.

The Prius, the Debate, and the Road Ahead

Toyota's most consequential recent decision came in 1997 when it launched the original Prius, the world's first mass-produced hybrid electric vehicle. The Prius was not an immediate commercial sensation. It was, for much of its early life, a statement of intent: a proof of concept that a mainstream automaker could build a vehicle that used significantly less fuel without asking drivers to change their behaviour in any dramatic way.

That statement eventually became a commercial reality. Toyota now sells more than 40 hybrid models worldwide, and the hybrid powertrain has become central to the company's environmental positioning. The Prius itself has sold millions of units globally and reshaped public perception of what a fuel-efficient car could be.

The criticism that has followed, however, is pointed. While rivals have raced to develop fully battery-electric vehicles, Tesla is building an entirely new market, Volkswagen is betting billions on electrification, GM and Ford are committing to all-electric futures, and Toyota has moved more cautiously. The company has instead invested significantly in hydrogen fuel cell technology, exemplified by the Toyota Mirai. Hydrogen has significant theoretical advantages: fast refuelling times, longer range, and no battery degradation. It also has significant practical disadvantages: minimal refuelling infrastructure, high costs, and an adoption trajectory that has lagged far behind battery electric vehicles in virtually every major market.

Whether Toyota's bet on hydrogen will ultimately prove visionary or mistaken is a question that cannot yet be answered. What is clear is that the company has staked a significant portion of its long-term strategy on a technology that the rest of the industry has largely passed by and that the outcome of that bet will shape both the company and the broader automotive landscape in ways that are still unfolding.

What Toyota Actually Is

It is easy to describe Toyota in superlatives, largest, oldest, most productive, most copied, and lose sight of what makes the company genuinely interesting.

Toyota is a company that started by selling a loom patent, nearly went bankrupt twice before it found its footing, learned manufacturing from Ford and then built a system that made Ford's look inefficient, failed in its first attempt at the American market and then conquered it, invented the mass-market hybrid and is now debating whether to follow the rest of the world into full electrification or chart its own course.

It is, in other words, a company that has spent nearly a century being underestimated, adapting, and proving the doubters wrong. Whether it will do so again with hydrogen is the most interesting automotive question of the coming decade.

The loom patent money has been well spent.
