Metaplanet Inc., the foremost corporate Bitcoin holder in Japan, has finalized an agreement to purchase 100% of Siiibo Securities Co., Ltd. This transaction, valued at approximately 2.1 billion yen (about $13.1 million), was disclosed by the Tokyo-listed entity on Friday, June 12.
This acquisition, slated for completion on July 13, 2026, signifies the inaugural major step in “Project Nova” — Metaplanet’s comprehensive strategy aimed at establishing a Bitcoin-centric financial platform within Japan. Post-completion, Siiibo Securities will be rebranded as Metaplanet Securities Inc.
Through this deal, Metaplanet secures a crucial asset it previously lacked: a Type I Financial Instruments Business Operator license. This regulatory approval is mandated by Japanese law for the creation and distribution of financial instruments targeted at retail consumers.
This official standing, coupled with Siiibo’s existing clientele and digital infrastructure, strategically positions the conglomerate to commence offering investment vehicles linked to Bitcoin to individual investors in Japan.
Siiibo Securities, established in January 2019, operates a digital marketplace for private placement corporate bonds, a sector historically accessible only to institutional investors and affluent individuals.
The company has supported over 40 bond issuers and facilitated more than 100 bond offerings, cultivating a significant track record within Japan’s retail corporate bond market.
Metaplanet’s Strategic Motivation
As of May 31, 2026, Metaplanet held 40,177 BTC, representing a net asset value of 457.6 billion yen. This substantial holding makes it the third-largest corporate Bitcoin owner globally and the largest in Asia.
The company has dedicated the past two years to accumulating Bitcoin as a treasury reserve, a tactic reminiscent of MicroStrategy’s approach in the United States. Project Nova represents the subsequent phase: transforming this treasury reserve into the foundation of a financial services enterprise.
Simon Gerovich, President and CEO of Metaplanet, characterized the acquisition as a fundamental strategic pivot.
“We perceive Bitcoin not merely as a treasury reserve asset, but as the bedrock upon which the next generation of financial ecosystems will be built,” Gerovich stated in the official announcement. “Siiibo Securities’ Type I Financial Instruments Business license, its corporate bond platform, and its established customer network equip us with the necessary instruments to realize this vision.”
Metaplanet has identified four primary areas of synergy anticipated from this integration. The company intends to make Siiibo’s existing bond products available to its shareholder base, which comprises approximately 250,000 investors. Furthermore, Metaplanet plans to develop financial products tied to BTC, including BTC-linked bonds, for distribution via the Siiibo platform.
Joint underwriting of bond and digital security issuances is planned in conjunction with Metaplanet Ventures Inc., with a particular emphasis on emerging companies within the cryptocurrency and decentralized finance sectors.
Additionally, a pilot initiative for security tokens and other digitized financial instruments is included in their future plans.
Kazuki Komura, CEO of Siiibo Securities, expressed that the merger will facilitate novel capital formation structures previously unattainable.
“By amalgamating the financial, technological, and community-building expertise of both firms, we are confident in our ability to pioneer new avenues for capital generation and investment experiences,” Komura remarked.
Metaplanet indicated that the acquisition will be financed through its existing cash reserves and borrowed funds. They also have the option to utilize Bitcoin-backed credit lines, which collectively offer a borrowing capacity of up to $500 million.
