Who owns Rakuten? Ownership structure explained (2026)

Rakuten is one of Japan's largest internet companies, and it is unusual among global tech giants because a single founder still holds the top job and a controlling block of stock nearly three decades after launch. Hiroshi Mikitani built the business from a small online shopping mall in 1997 into a sprawling group that sells everything from marketplace listings and credit cards to mobile phone service and e-books.

That breadth is the reason its ownership is worth understanding. Rakuten is not a focused pure-play. It is a conglomerate whose fortunes now hinge on an expensive bet on becoming Japan's fourth mobile carrier, a bet funded partly by outside investors who bought in during a 2021 capital raise. Who holds the stock, and who holds the votes, shapes how much freedom Mikitani has to keep funding that bet.

This article breaks down Rakuten's ownership: how public and private the company really is, how much control the founder retains, which institutions and strategic partners sit on the register, and why the structure matters for the company's future.

Rakuten was founded on February 7, 1997 by Hiroshi Mikitani, originally under the name MDM, Inc., and renamed Rakuten in 1999. Its first product was Rakuten Ichiba, an online marketplace that let small merchants open storefronts, a model closer to a shopping mall than to a first-party retailer, and a contrast with how Amazon blends marketplace and own-account retail. The company is based in Setagaya, Tokyo, at a campus known as Crimson House.

Today Rakuten Group operates through three reported segments. Internet Services covers Rakuten Ichiba, travel, digital content, and advertising. FinTech covers Rakuten Card, Rakuten Bank, Rakuten Securities, and insurance. Mobile covers Rakuten Mobile, the carrier network, and the Rakuten Symphony telecom-software business. The group also owns the Viber messaging app and the Kobo e-reader and e-book business. Rakuten is an investor as well as an operator: it once held one of the earliest large stakes in the ride-hailing company Lyft, whose shareholder base is now largely public, and an early position in the image-discovery platform Pinterest, whose ownership tilts toward its founders and index funds.

For the full year ended December 31, 2025, Rakuten reported record revenue of 2.50 trillion yen, up 9.5% from the prior year, its 29th consecutive year of record revenue. Operating income was 14.4 billion yen. The FinTech segment produced revenue of 975.9 billion yen, and the Internet Services segment produced 1.37 trillion yen. Despite that, the group posted a net loss attributable to owners of 177.9 billion yen, its seventh consecutive annual net loss, driven by mobile investment, financing costs, and impairment charges.

Rakuten is a public company. Its shares trade on the Prime Market of the Tokyo Stock Exchange under code 4755, and anyone can buy them. The company had roughly 2.17 billion shares issued as of December 31, 2025. But "public" understates how concentrated control is. The founder, his family, and their holding vehicles together own close to a quarter of the company, which makes Rakuten a listed company with a controlling shareholder rather than a widely held one.

Hiroshi Mikitani is the single most important shareholder. As of December 31, 2025, he directly held 8.14% of Rakuten's shares. He also controls Crimson Group, LLC, an investment company that held 10.43%, making it the second-largest holder on the register. His wife, Haruko Mikitani, held 5.19%, and two further family-linked entities, Mikitani Kosan, Inc. and Spirit Inc., held 1.88% each. Added together, the founder, his family, and their affiliated vehicles hold roughly 27% of the company.

Rakuten uses a single class of common stock, so this control comes from the size of the family bloc rather than from super-voting shares. That distinction matters: unlike founders who lock in control with dual-class structures, Mikitani's grip depends on his family continuing to hold that quarter-stake and on his standing as chairman and CEO.

The register mixes the founder's holdings, Japanese trust banks that hold shares on behalf of institutional investors, one strategic corporate investor, and global asset managers. The table below shows the largest holders as of December 31, 2025.

The Master Trust Bank of Japan and Custody Bank of Japan are the two largest names on the register, but they are custodians rather than economic owners. They hold shares in trust accounts on behalf of pension funds, index funds, and other institutions, so their combined double-digit stake represents many underlying investors, not a single decision-maker.

Japan Post Holdings is the standout strategic shareholder. The state-linked postal and financial group invested about 150 billion yen in Rakuten during a 2021 capital raise and remains a roughly 6% holder. The tie-up gave Rakuten cash for its mobile and logistics push and gave Japan Post a partner for digital transformation and delivery.

Global asset managers appear through custodians and nominee accounts. Passive giants such as BlackRock and Vanguard hold Rakuten as part of broad international index funds, and firms including Goldman Sachs and Nomura Asset Management show up on the shareholder list. None of these holders comes close to challenging the founder's bloc.

Because Rakuten has a single class of shares, one share carries one vote. There is no founder super-share. Control therefore rests on the arithmetic of the register: the roughly 27% held by Mikitani, his family, and their vehicles is large enough to dominate shareholder votes in practice, given that the rest of the float is dispersed across institutions and retail investors. Strategic holders like Japan Post are partners rather than activists, which further insulates Mikitani from outside pressure. Founder-anchored Asian internet companies are common, but the balance varies: a useful contrast is Alibaba's more dispersed ownership, where no founding family holds a comparable personal bloc.

Hiroshi Mikitani is the central figure. He founded the company in 1997 and holds the combined titles of Representative Director, Chairman, President, and CEO. He sets strategy, chairs the board, and remains the public face of the company. His concentration of both equity and executive titles is the defining feature of Rakuten's governance.

Masayuki Hosaka, a co-founder, serves as Vice Chairman and has been part of the leadership since the early years. Beyond the two founders, Rakuten's board includes a mix of internal executives and outside directors, consistent with the governance expected of a Tokyo Prime Market listing. Precise board membership changes at each annual general meeting, so current appointments should be checked against the company's latest disclosure.

What is confirmed is the shape of control: Mikitani holds the votes, the chair, and the chief executive role at once. What is less visible from public filings is the day-to-day division of authority among the segment heads who run e-commerce, fintech, and mobile, since Rakuten discloses far less about operating leadership than it does about its top shareholders.

The dominant issue hanging over Rakuten's ownership is the cost of Rakuten Mobile. Building a nationwide fourth network from scratch has drained cash for years, producing a long run of quarterly operating losses and driving the group to seven consecutive annual net losses through FY2025. The Mobile segment posted a non-GAAP operating loss of 161.8 billion yen in 2025 even as revenue grew and the unit reached its first full-year EBITDA profit. The build-out left Rakuten carrying heavy debt, and the company has spent recent years refinancing and rolling over large bond maturities. Rising interest costs on that debt are a direct contributor to the group's net losses.

To keep funding mobile, Rakuten has raised money repeatedly, including the 2021 share sale to Japan Post, Tencent, and Walmart, bond issues in Japan and abroad, and partial listings and stake sales in group businesses such as Rakuten Bank and Rakuten Securities. Each equity raise dilutes existing holders, and the reliance on capital markets ties the company's freedom of action to investor appetite and credit conditions. For a founder whose control rests on the size of his stake rather than special voting rights, repeated dilution is a slow pressure on that control.

As a licensed mobile operator and a major financial-services provider, Rakuten sits under Japanese telecom and financial regulation, including rules on network reliability, spectrum, and the handling of customer data across its e-commerce, card, bank, and mobile arms. Operating a bank, a securities broker, and a card issuer alongside a marketplace and a carrier concentrates a large volume of sensitive customer information inside one group, which raises the stakes on data protection and cross-selling practices. The tangle of mobile debt, refinancing exposure, and cross-group data risk is the kind of map a risk register template is built to keep track of.

Rakuten's ownership structure explains why the company can pursue an expensive, contrarian strategy that public-market pressure might otherwise have killed. Founder control means Mikitani can keep funding the mobile network through years of losses without being forced out by activist investors demanding a retreat. That is a genuine advantage when the payoff is long-dated, but it also means the strategy lives or dies on one person's judgment.

For investors, the structure is a double-edged sword. A committed founder with a large stake aligns his interests with long-term value, and Japan Post's presence signals strategic backing. But the same concentration limits the influence of minority shareholders, and the steady dilution from capital raises has eroded the value of existing stakes as the share price fell from its pandemic-era highs. Sizing what the group's mix of e-commerce, fintech, and mobile is actually worth is the kind of exercise a business valuation calculator is built for. Anyone buying Rakuten stock is effectively backing Mikitani's mobile thesis.

For customers, ownership matters because it keeps the sprawling "Rakuten Ecosystem" intact. The founder's strategy is to bind shoppers, cardholders, bank customers, and mobile subscribers together with the Rakuten Points loyalty program, so control of the parent keeps that cross-selling machine pointed in one direction. If control were to pass to an owner focused on a single segment, the group could be broken up and the ecosystem unwound.

Finally, the structure matters for the company's resilience. Because control depends on the family bloc rather than super-voting shares, a large enough external raise, or a sale of family holdings, could gradually loosen Mikitani's grip. That makes the pace of future capital raises one of the most important things to watch in Rakuten's ownership story.

Rakuten Group, Inc. is a publicly traded company listed on the Tokyo Stock Exchange, so it is owned by its shareholders. The largest is founder Hiroshi Mikitani, who together with his family and their holding vehicles controls roughly 27% of the shares. Trust banks holding stock for institutions, the strategic investor Japan Post Holdings, and global asset managers own most of the rest.

Hiroshi Mikitani is the Chairman, President, and CEO of Rakuten Group. He founded the company in 1997 and has led it ever since, making him one of the longest-serving founder-CEOs among major global internet companies.

Yes. Rakuten trades on the Prime Market of the Tokyo Stock Exchange under the ticker code 4755. It had a market value of about 1.56 trillion yen, or roughly 10 billion US dollars, as of September 16, 2026.

No. Rakuten Group is itself the parent company of a large group of businesses, including Rakuten Card, Rakuten Bank, Rakuten Mobile, Rakuten Securities, Viber, and Kobo. No single company owns Rakuten; it is controlled by its founder and public shareholders.

As of December 31, 2025, the largest holders were The Master Trust Bank of Japan at 10.84% (a custodian for institutions), the founder's investment vehicle Crimson Group at 10.43%, Hiroshi Mikitani personally at 8.14%, and Japan Post Holdings at 6.04%. Family members and holding companies account for much of the remaining founder-linked bloc.

Rakuten's group-level net losses come mainly from building Rakuten Mobile, Japan's fourth mobile network. The construction and marketing costs, plus rising interest on the debt raised to fund them, have outweighed profits from the e-commerce and fintech businesses. In FY2025 the mobile unit reached its first full-year EBITDA profit and passed 10 million subscribers, but the group still posted a net loss of 177.9 billion yen.
