SoftBank Group

SoftBank Group Corp. (ソフトバンクグループ株式会社) is a Japanese multinational investment holding company headquartered in Minato, Tokyo which focuses on investment management. The group primarily invests in companies operating in technology that offer goods and services to customers in a multitude of markets and industries ranging from the internet to automation. With over $100 billion in capital at its onset, SoftBank's Vision Fund is the world's largest technology-focused venture capital fund. Fund investors included sovereign wealth funds from countries in the Middle East.

The company is known for the leadership of its controversial   founder and largest shareholder Masayoshi Son. Its investee companies, subsidiaries and divisions, including several unprofitable unicorns, operate in robotics, artificial intelligence, software, logistics, transportation, biotechnology, robotic process automation, proptech, real estate, hospitality, broadband, fixed-line telecommunications, e-commerce, information technology, finance, media and marketing, and other areas. Among its most internationally recognizable current stockholdings are stakes in Arm (semiconductors), Alibaba (e-commerce), OYO Rooms (hospitality), WeWork (coworking) and Deutsche Telekom (telecommunications). SoftBank Corporation, its spun-out affiliate and former flagship business, is the third-largest wireless carrier in Japan, with 45.621 million subscribers as of March 2021. Poor investment decisions of Masayoshi Son’s SoftBank Group led to a panoply of losing investments across the history of the company.

SoftBank was ranked in the 2017 Forbes Global 2000 list as the 36th largest public company in the world and the second-largest publicly traded company in Japan after Toyota.

The logo of SoftBank is based on the flag of the Kaientai, a naval trading company founded in 1865, near the end of the Tokugawa shogunate, by Sakamoto Ryōma.

Although SoftBank does not affiliate itself to any traditional keiretsu, it has close ties with Mizuho Financial Group, its primary lender.

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
In the 1990s, Son made large investments in Internet services and the so-called new economy in general. SoftBank bought COMDEX from The Interface Group on 1 April 1995 for $800 million and ZDI on 29 February 1996. SoftBank sold COMDEX to Key3Media, a spin-off of Ziff Davis, in 2001.

In another highly publicized investment, SoftBank bought 80% of memory manufacturers Kingston Technology in 1996. When the owners-founders (John Tu and David Sun) announced plans to distribute $100,000,000 of the $1.5B windfall to Kingston employees, it created a very high-profile media stir that lasted well through the 1996 Christmas season; it was on all US networks, as well as international media. 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.

SoftBank Corp.
SoftBank Corp. (ソフトバンク株式会社) is SoftBank's telecommunications subsidiary, providing both mobile and fixed-line services. It was called SoftBank Mobile until July 2015, when the Group merged SoftBank BB Corp., SoftBank Telecom Corp. and Ymobile Corporation to reflect its fixed-line and ISP operations.

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.

Vodafone changed the name of its multimedia data services from J-Sky to Vodafone live! and used J-Sky's principles, technologies, and business models to introduce the WAP-based Vodafone live! in Vodafone's other markets. 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.

On 4 June 2008, SoftBank Mobile announced a partnership with Apple and brought the iPhone (3G) to Japan later in 2008. SoftBank Mobile was the only official carrier of the iPhone in Japan until the release of iPhone 4S in 2011, when au by KDDI began to offer it.

Technology

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.

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.
