At age 16, Son moved from Japan to California in the U.S. He finished high school very quickly by taking special exams.
Son then went to the University of California, Berkeley. He studied economics and computer science. When he was 19, he became very excited about computer technology. He believed it would change the world.

Son graduated from Berkeley in 1980. He started a video game company called Unison World. He later sold this company for almost $2 million.
When he returned to Japan, Son decided to use his family's original Korean surname. This made him a role model for many ethnic Korean children in Japan.
SoftBank

SoftBank's Journey
Masayoshi Son started SoftBank in 1981. At first, it sold computer software. Over time, it grew into a major telecommunications company in Japan. Later, it became SoftBank Group Corp., a company that invests in other businesses.
Even before it became a main investment company, SoftBank often invested in other businesses. Some investments were very successful, like Alibaba Group in 1999 and Yahoo! in 1995. Others did not work out as well.
In 2021, Masayoshi Son stepped down as CEO of SoftBank Mobile, which is the mobile phone part of SoftBank.
Yahoo! and Alibaba Investments

Son was one of the first people to invest in internet companies. He bought a share of Yahoo! in 1995. He also invested $20 million in Alibaba in 1999. For a short time, he was the richest person in the world.
SoftBank owned a large part of Alibaba. This was worth a lot of money. Son also helped start Yahoo! BroadBand in Japan. This company became Japan's top broadband provider. In 2020, Son left the Alibaba board. By 2023, SoftBank had sold most of its shares in Alibaba.
Arm Holdings
In 2016, SoftBank announced plans to buy Arm Holdings. Arm Holdings is a UK company that designs computer chips. This was a very large purchase for a European technology company. The deal was completed in September 2016.
In 2020, SoftBank Group agreed to sell Arm Limited to Nvidia, a U.S. chip-maker. This deal was worth a lot of money. SoftBank said that combining Arm and Nvidia would create a company that would lead the future of artificial intelligence. However, the deal with Nvidia did not happen. This was because regulators in the U.S. and Europe had concerns. After this, Arm filed to be listed on the U.S. stock market in 2023.
Sprint Corporation
In the 2010s, SoftBank bought a large share of Sprint. Sprint is a telecommunications company in the U.S. SoftBank later owned even more of Sprint.
Sprint and T-Mobile US merged in 2020. This was a big deal worth $26 billion. By 2021, SoftBank Group Corp. had bought shares in Deutsche Telekom, which is T-Mobile's parent company.
Solar Power
After the Fukushima Daiichi nuclear disaster in 2011, Masayoshi Son spoke out against nuclear power. He started investing in a nationwide solar power network for Japan.
In 2018, Son announced he was investing in a huge solar project in Saudi Arabia. He also planned to support a lot of new renewable energy projects in India.
Vision Fund
The SoftBank Group started the Vision Fund in 2017. This fund was created to invest in new technologies. These include artificial intelligence (AI), robotics, and the internet of things. The goal was to invest in many AI companies. It also invested in companies that aimed to change real estate, transportation, and shopping. Son wanted to connect the CEOs of all these companies.
In 2019, a second Vision Fund was created. SoftBank itself put a lot of money into this fund.

By 2020, the first fund had invested in many companies. These included Coupang, Didi, Doordash, Fanatics, Grab, Oyo, Paytm, Uber, and WeWork. However, the fund also faced challenges. Some investments did not do well, especially during the COVID-19 pandemic.
Son became well-known as an investor after the huge success of Alibaba Group. He had invested in Jack Ma's Alibaba when it was a young company in 2000. He also created the SoftBank Vision Fund in 2017. This fund was very large and aimed to support technology startups. However, some of the fund's investments, like WeWork, faced big losses. This led to questions about the fund's strategy.
By 2022, the SoftBank Vision Fund reported a very large loss. This was because the value of its investments went down. Some people said that Son's investment choices were sometimes too quick or not well-timed. Despite these challenges, Son continues to be a major figure in technology investment.
