Masayoshi Son is a Japanese technology entrepreneur, investor, and philanthropist who is best known as the founder, chairman, and chief executive officer of SoftBank Group Corp., a Japanese multinational conglomerate holding company that focuses on investment management. By December 2022, he held a 34.2% stake in the company. He has often been mocked as a ‘gambler’ because the vast majority of his investments have failed. It has often been argued that Masayoshi’s reputation as an investor has largely been saved by his USD 20 million investment in 2000 in the Alibaba Group (a Chinese multinational technology company specializing in e-commerce, retail, internet, and technology), a stake that had risen to about USD 110 billion by October 2018. For many years, Masayoshi had even held the unwanted record for being the person who had lost the most money in history, a mantle that was later assumed by Elon Musk.

Masayoshi Son Facts

  1. Born in 1957 in Tosu, Japan, Masayoshi is a 3rd generation ‘Zainichi Korean’. The term refers to ethnic Koreans who have permanent residency status in Japan and whose ancestors immigrated to Japan before 1945.
  2. Masayoshi’s father used to raise pigs and chickens and later started an illegal saké (an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran) business. The business went on to become so profitable that his family became the first in its town to own a car.
  3. During his time at the University of California, Berkeley, with the help of some professors, Masayoshi created an electronic translator that he sold for USD 1.7 million to Sharp Corporation, a Japanese multinational company that designs and manufactures electronic products.
  4. Around this time, Masayoshi also ran an entrepreneurial venture under which he imported video game machines from Japan and installed them in dormitories and restaurants in California. He earned USD 1.5 million through this venture.
  5. After graduating from the University of California, Berkeley, in 1980, he started a video game company called Unison World. He later sold it for around USD 2 million. Masayoshi naturalized as a Japanese citizen in 1990.
  6. In 1995, as one of the earliest investors in internet firms, he bought a stake in Yahoo!, an American web services provider. In September 2001, Masayoshi established Yahoo! BroadBand with the Japanese subsidiary of Yahoo!.
  7. A few years later, Yahoo! BroadBand acquired Japan Telecom, the then-3rd-largest broadband and landline provider in the country. Yahoo! BroadBand went on to become Japan’s leading broadband provider.
  8. In the 2010s, through his holdings in SoftBank Group Corp., Masayoshi acquired a 76% share (which later swelled to 84%) in Sprint Corporation, an American telecom company that was the 4th-largest mobile network operator in the United States before it merged with T-Mobile US (an American wireless network operator) in April 2020.
  9. In 2011, Masayoshi pledged nearly USD 120 million, and his remaining salary until retirement, for the support and rehabilitation of the victims of the Tōhoku earthquake and the tsunami caused by it. It was, at that time, the most powerful earthquake ever recorded in Japan, and the 4th most powerful earthquake in the world since modern record-keeping began in 1900. The official figures released in 2021 reported 19,759 deaths, 6,242 injuries, and 2,553 people missing.
  10. In September 2016, SoftBank Group Corp. acquired Arm Holdings (a British semiconductor and software design company) for approximately £24 billion ($34 billion) – the then-largest purchase of a European technology company.
  11. Masayoshi’s 3-story Tokyo mansion, valued at USD 50 million, includes a golf range that is fitted with technology that can mimic the weather conditions of the world’s top golf courses.
  12. He also owns the SoftBank Hawks, a professional Japanese baseball team that competes in Nippon Professional Baseball, the highest level of baseball in Japan.
  13. In June 2023, Son revealed that he was a heavy user of ChatGPT and was talking to OpenAI CEO Sam Altman almost daily.
