## History
### Founding and early years

SoftBank was founded in September 1981 as SOFTBANK Corp by then-24-year-old Masayoshi Son, initially as a software distributor. The company entered the publishing business in May 1982 with the launches of the Oh! PC and Oh! MZ magazines, about NEC and Sharp computers respectively. Oh!PC had a circulation of 140,000 copies by 1989. It would go on to become Japan's largest publisher of computer and technology magazines and trade shows.
In 1994, the company went public, valued at $3 billion. In September 1995, SoftBank agreed to purchase US-based Ziff Davis publishing for $2.1 billion.

### 1995–2009 expansion

A few years later, in 1999, after the market for memory softened substantially, SoftBank sold the company back at a loss to the original owners for about a third of the original price.
In October 1999, SoftBank became a holding company. In 2000, SoftBank made its most successful investment – $20 million to a then-fledgling Chinese Internet venture called Alibaba. This investment turned into $60 billion when Alibaba went public in September 2014.

### J-PHONE

SoftBank's mobile communications arm began with the formation of Japan Telecom in 1984. The Digital Phone Group (デジタルホン, DPG, three local companies) mobile phone division was formed in 1994, and J-PHONE Co., Ltd. (J-フォン) was formed in 1999 by the DGP/ Digital TU-KA Group merger (DTG, six local companies, not to be confused with TU-KA). Japan Telecom owned a stake of 45.1%.
J-PHONE grew steadily for a decade by introducing new services and enhancements such as SkyWalker for PDC, SkyMelody ringtone download, the Sha-Mail picture mail introduced following camera phones developed by SHARP, the mobile multimedia data service J-Sky modeled after NTT DoCoMo's i-mode, and advanced Java services based on JSCL, modeled after NTT DoCoMo's DoJa based i-appli.

### Vodafone

In October 2001, the British mobile phone group Vodafone increased its share to 66.7% of Japan Telecom and 69.7% of J-Phone. On 1 October 2003, the company's name and the service brand changed to Vodafone, while the division was called Vodafone K.K. or Vodafone Japan.
However, in January 2005, Vodafone Japan lost 58,700 customers and in February 2005 lost 53,200 customers, while competitors NTT DoCoMo gained 184,400 customers, while Au by KDDI gained 163,700, and Willcom gained 35,000. While as of February 2005, DoCoMo's FOMA 3G service had attracted 10 million subscribers and KDDI's 3G service had attracted over 17 million subscribers, Vodafone's 3G service only attracted 527,300 subscribers. Vodafone 3G failed to attract subscribers because Vodafone reduced investments in 3G services in Japan in 2002/3; handsets did not fully match the needs and preferences of Japanese customers. At the end of February 2005, Vodafone Japan had 15.1 million customers. By the end of October 2005, the number of subscribers had fallen below 15M. During the same period, NTT DoCoMo gained 1.65 million customers, and KDDI/AU gained 1.82 million customers. Vodafone-Japan had only 4.8% of Japan's 3G market.

At the end of February 2005, Vodafone live! had 12.907 million subscribers in Japan. By the end of October 2005, the number of Vodafone live! subscribers had fallen by 138,000.
In March 2006, Vodafone began discussing the sale of the Vodafone Japan unit to SoftBank. Vodafone was unable to satisfy customers. Handsets had user interfaces that differed too much from the Japanese interface and lacked competitive features.

### SoftBank Mobile

On 17 March 2006, Vodafone Group announced it had agreed to sell Vodafone Japan to SoftBank for about US$15.1 billion. On 18 May 2006, the unit was renamed "SoftBank Mobile Corp.", effective 1 October 2006.

## Marketing

Since May 2006, SoftBank's telecommunications marketing and commercials have principally revolved around "Otosan sujan karki", the canine patriarch of the otherwise human "Shirason, Kaito" family. "Otosan" translates to father, and the character, a Hokkaido dog, indeed acts as the father of the family, along with the son "Kojiro" (starred by Dante Carver), mom "Masako" (Kanako Higuchi), and daughter "Aya" (Aya Ueto). The advertising series proved to be popular: CM Research Center ranked the Otousan adverts as the most popular in Japan between 2007 and 2012, based on monthly surveys of 3,000 randomly selected adults.
SoftBank partnered with the Ingress augmented reality game, supporting the branded "SoftBank Ultra Link" in-game item.

### Sponsorship

SoftBank bought a "team" for the America's Cup. The team was named SoftBank Team Japan, and Yanmar came on board. SoftBank Team Japan raced in the 2017 races held in Bermuda. The team members come from various backgrounds, most of whom were not Japanese.
The company was the official jersey sponsor of the Japanese national basketball team at the official 2017 Asian Basketball Championship in Lebanon as well as the 2019 FIBA World Cup.
SoftBank has also owned the Fukuoka SoftBank Hawks, a Japanese professional baseball team based in Fukuoka, since 2005. The SoftBank logo appears on the jersey, and the team has won seven Japan Series championships under SoftBank, all of which came between 2011 and 2020.

## Baby bonus

In 2015, SoftBank, along with some other companies in Japan, offered a baby bonus for employees who have children. The payments range from 50,000 yen for the first child to 5 million yen for the fifth child.

## Vision fund investments

SoftBank Investment Advisers oversees SoftBank's Vision Fund, created in 2017, which invests in emerging technologies like artificial intelligence, robotics and the internet of things. It intended to develop a portfolio of 125 AI companies. According to the fund and Son, it also invested in companies to revolutionize real estate, transportation, and retail. Son claimed he would make personal connections with the CEOs of all companies funded by Vision Fund in order to boost synergies among them. Son’s original plans were to raise $100 billion for a new fund every few years, investing about $50 billion a year in startups. By 2023, after the launch of Vision Fund 1 and 2, the dismal performance of SoftBank’s funds had cast a shadow over the initial exuberance of both Masayoshi Son and his company regarding its huge, largely unprofitable intercorporate investments that had become the main mission, vision and purpose of the entire SoftBank Group.

## SoftBank Ventures Asia

SoftBank Ventures Asia (SBVA) was the global early-stage venture capital arm of the SoftBank Group The firm focused on early-stage ICT investments – including Artificial Intelligence (AI), the internet of things (IoT), and smart robotics. By October 2021, SBVA had backed more than 250 companies in 10 countries with US$1.3 billion fund under management.
SoftBank Ventures Asia (SBVA) was founded in 2000 as SoftBank Ventures Korea and began its focus on South Korean market and its early-stage ventures. SBVA’s one of the early investments in South Korea included Nexon Co, now a Korean-Japanese gaming publisher that was the largest IPO in Japan for 2011.
SoftBank Ventures Asia (SBVA) expanded its focus beyond South Korea since 2011 and made several notable investments in Southeast Asia, such as Tokopedia, an Indonesian e-commerce platform, and Carro, Singapore's used-car platform. In 2018, SBVA launched a $300m venture fund ‘China Venture Fund I’, targeting Chinese start-ups, then immediately trailed by ‘SoftBank Acceleration Fund’ with $300M the following year. With continuous investment across Asia and beyond, the company renamed itself as SoftBank Ventures Asia to reflect its broadened focus on startups in the Asia-Pacific region beyond South Korea, and opened offices in Seoul, Singapore, and Beijing.
With the company’s extended expertise in ICT investment, SBVA is aiming towards two investment themes, which were ‘technology innovation’ in AI, Robotics, Semiconductor, Mobility, and AR/VR, and ‘market innovation’ in consumer, enterprise, shared economy, healthcare, etc. SBVA created $160M ‘future innovation fund’ in March 2021, focusing on AI start-ups and made investment in AI sector including VoyagerX, AI software developer, Upstage AI, AI solution provider, and MarqVision, AI-powered intellectual property (IP) protection platform.
In April 2023, it was known that Masayoshi Son's SoftBank Group would sell its early-stage venture capital arm SoftBank Ventures Asia to Singapore-based The Edgeof, a newly formed investment firm led by Son's youngest brother, Taizo Son, as SoftBank Group grappled with steep losses in a myriad of investments made around the world. The operation raised governance concerns.
