Founding
In September 1981 the 24-year-old Son Masayoshi established Japan SoftBank in the city of Fukuoka. The distribution of software for personal computers had no wholesaling function equivalent to the distributors of the book trade, and he conceived a business that would join software houses, retail shops and users through a single company. He signed exclusive distribution contracts with Sharp and NEC and built a nationwide wholesale network. The following year, 1982, he widened into publishing specialist magazines, and in July 1994 the shares were registered over the counter. The money the flotation raised went not into expanding the core business but into acquisitions and investments — in January 1996 the company set up Yahoo Japan Corporation as a joint venture with Yahoo of the United States, and put a further $91.9M (¥10bn) into the American parent to become its largest shareholder. By 1997 it was pressing on with aggressive acquisitions funded by bond issues, and the stock market looked with doubt on interest-bearing debt that exceeded revenue.
The Decision
Whatever the industry it moved into, the sum it committed always exceeded the cash it had. When it entered the ADSL market with Yahoo! BB in September 2001 it held on through losses larger than its revenue, and through talk of the company being broken up, to secure subscribers. In July 2004 it acquired Japan Telecom for about $3.1B (¥340bn), taking in corporate customers and optical fibre. The purchase of Vodafone's Japanese arm in April 2006 came to about $15.0B (¥1.75tn), structured as an LBO built around non-recourse loans secured on the acquired assets so that the effect on the parent's balance sheet was contained. In October 2012 it bought Sprint of the United States, entering the North American mobile market for about $18.4B (¥1.8tn). In July 2016 it acquired ARM of Britain, committing $30.3B (¥3.3tn) — the largest sum a Japanese company had paid up to that point. Interest-bearing debt swelled with every acquisition, and each time the gains on selling shares it held became the money for repayment.
Today
The valuation gains on its investments are an order of magnitude larger than the profit its businesses earn. Of consolidated revenue of $49.3B (¥7.8tn) in the year to March 2026, $44.5B (¥7.04tn) came from the domestic telecoms of its listed subsidiary SoftBank Corp. (9434), whose segment profit was $6.1B (¥965bn). In the same year the AI computing business, reorganised out of the Arm business, had revenue of $4.0B (¥640bn) and a loss of $868.1M (¥137bn). Against the $5.2B (¥828bn) the two businesses made between them, pre-tax profit reached $38.8B (¥6.13tn) and net income attributable to owners of the parent $31.6B (¥5tn). What made the difference is the investment stacked up since 2017, the year the company assembled the SoftBank Vision Fund on a scale of $89.2B (¥10tn). In January 2025 it launched Stargate, an AI infrastructure plan worth $500bn in all, with OpenAI and Oracle, and in March that year it acquired Ampere Computing of the United States, a designer of CPUs for servers, for $6.5bn. A company that had only held shares in the firms it backed moved to the side that owns everything from design through to product.
Competition
Its rivals changed from fellow telecoms operators to regulators and activist shareholders. Sprint, bought in 2013 for about $18.4B (¥1.8tn), carried the weight of capital spending in a fight to climb from fourth to third place in the United States, and left the consolidated accounts in April 2020 on its merger with T-Mobile US. Competition in the North American mobile market ended there. In March that year Elliott Management of the United States pressed on the discount of the share price to the value of the holdings, demanding shareholder returns and better governance, and the company settled on asset sales of up to $42.1B (¥4.5tn) and share buybacks totalling $23.4B (¥2.5tn). In September the same year a contract to sell the whole of Arm to Nvidia of the United States was agreed at up to $40bn, but it could not get past the competition concerns of Britain's CMA and a suit by the US FTC, and was terminated in February 2022. The Arm it could not sell listed on its own on the Nasdaq in September 2023 and became the asset supporting a market capitalisation of $129.3B (¥20.46tn) at the end of March 2026.

Founding Story

1981–2000From software distribution to internet investment

Across its first two decades SoftBank moved from wholesaling packaged software for personal computers to holding stakes in the companies that would run the internet, and it financed that shift almost entirely with borrowed money and market capital rather than its own earnings. At the peak of the dot-com bubble the group was worth $185.6B (¥20tn) on paper; when the valuation collapsed in the same year, it had to sell down the assets it had spent the 1990s buying.

A founding that filled the gap in software distribution, and an entry into publishing

In September 1981 the 24-year-old Son Masayoshi (孫正義)[1] established Japan SoftBank at Yonbancho, Chiyoda-ku, Tokyo[2], and began wholesaling packaged software for personal computers. The company's founding ground is the city of Fukuoka[3]. Personal computers were spreading and the range of software was widening, yet almost no business existed to carry goods from makers to retail shops, so a user had to trawl several microcomputer shops before reaching the title they wanted[4]. Son designed the business as an intermediate distributor that would deliver software the way a bookshop delivers a book[5]. He narrowed his options to a handful of industries on the criteria of low capital and high growth, hired staff, and spent a year and a half studying the market and the technology before committing to the founding[6]. In May 1982 the company launched the monthly magazines Oh! PC and Oh! MZ, entering publishing[7].

The founding capital was the $453,412 (¥100m) Son had earned from the patent on an automatic translation device he developed while studying in the United States[8]. Software could not serve as collateral, so no bank would lend to a distribution business at its founding, and the loan was executed only against personal guarantees from Sharp's Sasaki Tadashi (佐々木正) and others[9]. To make up for his lack of managerial experience, in 1983 Son brought in Omori Yasuhiko (大森康彦), formerly of Japan Guard Security, as president, and stepped back to become chairman[10]. Revenue grew from $9.2M (¥2bn) in the second year to $18.9M (¥5bn) in the third and $31.6M (¥8bn) in the fourth[11], reaching $48.2M (¥12bn) in the fifth, the year ended December 1985[12]. Oh! PC, launched the year after incorporation, also succeeded, and publishing grew into a pillar of the business alongside wholesaling[13]. Son returned to the presidency in 1986[14].

Flotation, and buying an information network

In July 1990 the company changed its name to SoftBank[15], and in July 1994 it registered its shares with the Japan Securities Dealers Association and went public[16]. Using the fundraising power that flotation gave it as a lever, from December that year it moved on the American trade-show operator Comdex and the Silicon Valley IT publisher Ziff-Davis[17]. The acquisitions were funded with bonds — beginning with a first unsecured straight bond of $106.3M (¥10bn) in February 1995[18], it issued twelve tranches totalling $2.0B (¥220bn) by November 1996[19]. Piling large acquisitions on borrowings one after another swelled interest-bearing debt to a scale greater than its revenue[20]. In January 1998 it listed on the First Section of the Tokyo Stock Exchange[21].

On 11 January 1996 SoftBank established Yahoo Japan Corporation as a joint venture with Yahoo of the United States, capitalised at $1.8M (¥200m)[22]. SoftBank held 60 per cent, or $1.1M (¥120m), and Yahoo Corporation 40 per cent, or $735,497 (¥80m)[23]; Son Masayoshi himself took the post of representative director and president[24]. The business was defined as providing a Japanese-language information search service within Japan and operating a mirror site[25] — an irregular joint venture in which the brand and the technology were borrowed from the American Yahoo while SoftBank held the capital and the management. In April the same year it put a further $91.9M (¥10bn) or so into Yahoo itself in the United States, becoming a larger shareholder than the founders. The American Yahoo was at that point no more than a venture with five or six employees and monthly revenue in the tens of millions of yen.

The market voiced concern that the run of acquisitions was draining the company's financial strength, and in August 1996 the question was put directly — could it stand the strain of one purchase after another?[26] Son Masayoshi replied that there was nothing to worry about, arguing that the acquisitions were not expensive purchases and that he was not chasing easy gains[27]. In the autumn of 1997 the deteriorating results of the acquired companies came to the surface, and clouds gathered over Son's expansionary line[28]. Criticism also gathered around an acquisition scheme that used a company Son owned personally; Son said that the responsibility for the shadowed parts is mine as well, while stating plainly that the acquisitions would continue[29]. Even in November that year the company had got through only by financial contrivance, and with the acquired businesses worsening nothing could be taken for granted[30].

The internet bubble, and shrinking the balance sheet in the collapse

In October 1999 SoftBank converted into a pure holding company[31], reorganising itself to hold and oversee the shares of its operating companies. In February 2000 it invested in Alibaba.com Corporation, making it an affiliate[32] and taking a stake that would later become the group's largest unrealised asset. At the peak of the internet bubble, the surge in the American Yahoo's share price briefly lifted SoftBank's market capitalisation to $185.6B (¥20tn). Most of that valuation rested on unrealised gains related to Yahoo[33], and the gap with the profit its businesses actually generated was wide. Less than six years after the 1994 flotation, a software wholesaler had turned into an investment company with one of the largest market capitalisations in the world[34].

The fall in share prices from the spring of 2000 pushed many of its investees into crisis[35]. SoftBank selected and sold the holdings that had appreciated, using the proceeds to shrink interest-bearing debt while clearing out the assets it had accumulated through the 1990s[36]. In parallel it went ahead with the purchase of Nippon Credit Bank, which had failed, been nationalised and been dealt with using public money[37]. Concerns were raised from the outset that a group centred on an investment company owning a bank would turn it into an in-house lender concentrating credit on affiliated firms[38]. In September 2000 President Homma (本間) of Nippon Credit Bank took his own life, and the wind turned against SoftBank after the acquisition[39].
