  • Foxconn
  • Larry Ellison 

SoftBank Vision funds have invested in hundreds of companies including emerging Asian e-commerce and e-payments companies Coupang and Paytm.

Masayoshi Son 孫 正義 biography

Masayoshi Son was born in 1967 and is currently 65 years old.

He is a 3rd generation Zainichi Korean, denoting Koreans who have lived in Japan for several generations and are Japanese citizens.

His grandfather emigrated to Japan and worked as a miner during the colonial period. Son was raised with his three brothers in the city of Tosu, Saga Prefecture, Japan.

Son’s upbringing was typical of many Korean immigrant families, using an adopted Japanese surname.

Their property was constructed illegally on land owned by Japan National Railways and his father made money by selling sake illegally.

However, education was a priority and Son showed promise in business by pursuing studies in English and computer science. 

Having seen an article on microchips in a magazine, Son became sure that computing would be a major commercial revolution and decided to invest his efforts in this area.

As a 16-year-old, Masayoshi Son moved from Japan to California, staying with friends and family while completing his high school studies. He later graduated with a B.A. in Economics from Berkley (University of California) in 1980. 

Masayoshi Son’s first business

In the late 1970s, while a student at Berkeley, Son developed an electronic translator that was sold to Sharp Corporation for almost $2 million.

Further profits were made by importing used video game machines from Japan, with the company sold for $2 million. 

Return to Japan

Son ditched the adopted Japanese surname of his family when he returned to Japan, dusting off the Korean surname, Son.

He founded SoftBank in 1981 to distribute software and publish magazines on computing.

By the late 1980s, SoftBank had diversified into telecommunications offering landline phone contracts deals.

The company grew large enough to challenge Nippon Telegraph and Telephone (NTT), Japan’s main telephone company.

From there the company made several notable acquisitions and investments that grew its wealth rapidly.
