Masayoshi Son's epic rise: from pig farming and pachinko to the world's biggest tech empire

Masayoshi Son's story is not about a privileged founder who discovered code early. It is about a man born into abject poverty—literally living with pigs in an illegal shack on a railroad in Japan—who became one of the world's most aggressive deal makers by absorbing his father's gambler's ethos and applying it to capital allocation at scale.

Son was born in 1957 in Tosu, a town in Kyushu. He is a third-generation Zainichi Korean, part of an ethnic Korean community granted permanent residency in Japan after World War II. His grandfather was part of an agricultural aristocracy in Korea and carried a deep disdain for business. His father, born in 1936, was different: an entrepreneur who broke from family tradition.

Son's father watched American B-29 bombers during the war and emerged convinced America was the future. In post-war Japan, as a Korean in a country that treated Koreans as underclass, he started by selling moonshine at age 14 to feed a family of seven. He gradually built capital through pig farming—free labor (his family), free land (railroad ghetto), and pigs that reproduced quickly. By the time Son was a child, his father had accumulated the equivalent of $100,000 and pivoted to pachinko, the Japanese gambling machine business.

The pachinko move was radical. Son's father built a massive club called Lions, spending $4 million—nearly all his capital—on a bet that required 5,000 to 10,000 players per day to succeed. The first month lost $350,000. He responded by adjusting the machine payout rates. The next month, he made $350,000 back. He lost it again, then won it back. Son watched his father oscillate between boom and bust, indifferent to bankruptcy. "I don't care if I go bust," his father said. "We'll run it back."

By the time Son was 14, the family lived a dual lifestyle: flashy cars and casinos for the working generation, while grandparents clung to the past. Son absorbed this completely. He would later say he had nightmares about pig farm smells. More importantly, he internalized that extreme risk-taking was normal, that losing everything was recoverable, and that the goal was to play the biggest game possible.

Early wins in America

A mentor named Den Fujita, who brought McDonald's to Japan, told Son to learn English and study computers. Son arrived in California at 16, advanced through high school in two weeks by testing out, spent two years at a college, then transferred to UC Berkeley to study economics. At Berkeley, he generated one business idea per day. He sold a translation device patent to Sharp Electronics for $2 million (before 1980). He then imported Space Invaders arcade machines, modified them, and made another $1 million. He founded a game software company and sold it for $2 million. Three hits in quick succession, before age 20.

Son returned to Japan in 1981 and spent 18 months in monk mode, developing research and building a knowledge base while relatives thought he was idle. He created 20 metrics to measure business ideas. The highest-scoring opportunity was personal computer software distribution—not building software, but buying finished software cheap and reselling it to retailers who lacked distribution arms.

This choice reveals his core logic: he was not an engineer and never identified as one. He was a deal maker assembling capital and people. Software distribution was capital-light, required no R&D, and aligned with his ability to charm vendors and retailers.

He founded SoftBank in 1981 with two part-time employees in a small office. He stood on an Apple box and declared: "In five years, we'll have $75 million in sales, supplying a thousand outlets, and we'll be number one in PC software distribution." Both employees quit immediately. He booked a giant trade show booth anyway—the size of Sony's and Toshiba's—despite being tiny. He invited vendors to exhibit for free and advertised them for free. Weeks later, Joshin Denki, a major retailer, called and said it needed a dedicated software supplier. Son pitched them hard on the idea that software drove hardware sales: if Joshin Denki had the best software, customers would come for the software and buy computers.

He closed the deal and secured something critical: Joshin Denki agreed to pay for product inventory, solving his working capital problem. SoftBank went from $10,000 in monthly revenue to $230 million in monthly revenue. Software distribution had massive margins and no inventory risk. SoftBank went public in 1994 at a $3 billion valuation and became Japan's largest PC software distributor.

The .com pivot

Son moved to Silicon Valley in 1995, early in the Internet boom but before the 2000 crash. In 1996, he met Yahoo cofounders Jerry Yang and David Filo. He offered them $100 million for 30 percent—an enormous check at a time when most VC funds could not write such amounts. When they hesitated, he gave them an ultimatum: "If you don't take my money, I'll invest in Excite or Lycos and kill you." He did not know who Excite or Lycos were. He asked them during the meeting and they told him. He immediately weaponized that information. Yahoo accepted. The IPO happened shortly after. Son made $150 million on day one.

From 1996 to 2002, he invested in 250 Internet startups—roughly one deal per week, sometimes five in a week. He was not trying to pick winners. He was riding the Internet wave with enormous volume and minimal due diligence. He launched teams across South Korea, Japan, Hong Kong, Australia, India, Mexico, and Brazil. He had presence in nearly every market before most American VCs thought about international expansion.

The critical move came when he met Jack Ma of Alibaba. Goldman Sachs, a previous investor, had grown reluctant to fund Alibaba further and was analyzing it on a spreadsheet basis. Son saw a glint in Ma's eye and committed $20 million at a $100 million valuation. As the deal progressed, he wound up with 34 percent of Alibaba. A critical advantage: Son sat on Cisco's board and saw router sales to China exploding, signaling massive Internet expansion there.

That $20 million investment turned into a $72 billion position—arguably the greatest venture bet of all time.

The .com crash hit hard. In March 2000, interest rates rose, stock markets plummeted, and SoftBank's market cap plunged 99 percent. Son personally lost $70 billion, a record at the time. But Alibaba survived, and he still owned it. He pivoted to durable, revenue-generating infrastructure: Yahoo Broadband, Japan Telecom, and Vodafone Japan (later rebranded as SoftBank Mobile). He was no longer betting on application-layer winners. He was betting on the pipes.

The Vision Fund and the pattern of massive bets

In 2010, Son released a 30-year vision presentation with outsized predictions: artificial intelligence will surpass the human brain, life expectancy in Japan will reach 200 years, a hyper-connected era will dawn. His central philosophy: "The information revolution will bring happiness for everyone." It was simple, intelligible, and non-technical. People mocked the slides. Many turned out correct.

The Vision Fund came in 2017. In 2016, on a flight to the Middle East, Son sketched a target of $30 billion, crossed it out, and wrote $100 billion instead. "Life's too short to think small," he said.

He pitched Crown Prince Mohammed Bin Salman with a 45-minute presentation. "I want to give you a trillion dollar gift. If you invest a hundred billion, I'll turn it into a trillion." MBS committed $45 billion on the spot. SoftBank added $28 billion. Apple, Qualcomm, Foxconn, and the UAE's Mubadala filled the rest. The Vision Fund launched with roughly $100 billion in capital.

Son's investment thesis was simple: AI, robotics, IoT, consumer tech. He invested in Uber, WeWork, ByteDance, Didi, DoorDash, Grab. He crossed borders freely—Chinese tech, American startups, Southeast Asian companies. He was one of the few truly global dealmakers. His capital often bridged huge transactions: Uber and Didi both took SoftBank money, and his simultaneous participation helped facilitate their eventual merger.

But the bets came with a cost. Many Vision Fund rounds became known as "suicide rounds"—so large that companies felt obligated to deploy massive capital quickly, and unless they achieved generational scale like Uber or DoorDash, they collapsed under the weight of huge preference stacks. He lost money on WeWork (Adam Neumann received $3 billion in his first meeting and was told to "be crazier"). He lost on Wirecard, a German payments processor that collapsed due to accounting fraud. Greensill Capital melted down.

In 2022, SoftBank announced a $27 billion loss. Chinese tech stocks like Alibaba and Didi were hammered by regulatory crackdowns. And it emerged that Son personally owed SoftBank $5 billion due to side deals gone wrong—deals that apparently happened without rigorous oversight.

Yet he did not quit. In 2021, despite the losses, SoftBank posted $46 billion in annual net profit. His core holdings—Alibaba, mobile, broadband—were still printing cash. One massive hit could cover ten WeWorks. He said, "When it rains, you open an umbrella," and remained an "unshakable optimist."

The return

He pivoted back to AI. By 2024, he was in talks on Stargate, a mega-infrastructure deal involving Sam Altman and Larry Ellison. He was ripping checks into OpenAI. His ARM holdings had appreciated enormously, erasing earlier losses. He was back in the game.

The pattern is unmistakable: Son operates in a fog of aggressive announcements, side deals, and personal commitments that his team is expected to "just make happen." He visualizes outcomes and moves capital as if they are already real. He does not sell early. He has never been short. His outcomes are 10-baggers or zeros.

And yet—and this is the key insight—he learned this from watching his father bet the family's entire fortune on pachinko parlors. Son grew up watching a man lose $350,000 in a month and make it back the next month, indifferent to the possibility of ruin. That ethos, applied across centuries of compound growth and global capital, produces a mogul unlike any other.

He is not Warren Buffett. He is not a researcher or a slow builder. He is a gambler with infinite conviction, playing the biggest game he can see. And because he has been right twice—Yahoo and Alibaba—he has earned the capital and credibility to keep playing.
