Son graduated from Berkeley with a B.A. in Economics in 1980, and started Unison in Oakland, CA, which has since been bought by Kyocera. Son's family had adopted the Japanese surname Yasumoto (安本), and Son had used that surname as a child. He decided to use his Korean surname instead on returning to Japan from the U.S., and became a role model for ethnic Korean children in Japan.
Son was an early investor in internet firms, buying a share of Yahoo! in 1995 and investing a $20 million stake into Alibaba in 1999. Son's holding company SoftBank owns 29.5% of Alibaba, which is worth around $108.7 billion as of 23 October 2018. Although SoftBank's stake in Yahoo! had dwindled to 7%, Son established Yahoo! BroadBand in September 2001 with Yahoo! Japan in which he still owned a controlling interest. After a severe devaluation of SoftBank's equity, Son was forced to focus his attention on Yahoo! BB and BB Phone. So far, SoftBank has accumulated about $1.3 billion in debt. Yet, Yahoo! BB acquired Japan Telecom, the then third largest broadband and landline provider with 600,000 residential and 170,000 commercial subscribers. Yahoo! BB is now Japan's leading broadband provider. In June 2020, Son stepped down from the Alibaba board.
In response to the Fukushima Daiichi nuclear disaster in 2011, Masayoshi Son criticized the nuclear industry for creating "the problem that worries Japanese the most today", and engaged in investing in a nationwide solar power network for Japan. In March 2018, it was announced that Son was investing in the biggest ever solar project, a 200GW development planned for Saudi Arabia as part of its Vision 2030.
In 2011 Son pledged to donate 10 billion yen ($120 million) and his remaining salary until retirement to support victims of the 2011 Tōhoku earthquake and tsunami.
In July 2016, SoftBank announced plans to acquire Arm Holdings for £23.4 billion ($31.4 billion) which would be the largest ever purchase of a European technology company. In September 2016, SoftBank announced that the transaction was complete. The total acquisition price was approximately £24 billion ($34 billion).
In July 2018, coverage indicated that Son "would underwrite most of 100 GW" of a planned 275 GW of new renewable provision in India by 2027.
