Japan's Metaplanet Acquires Siiibo Securities to Launch Bitcoin Financial Ecosystem

Japanese investment firm Metaplanet Inc. is making a significant move to expand its Bitcoin-centric strategy by acquiring Siiibo Securities Co., Ltd. This strategic acquisition, valued at approximately 2.1 billion yen (roughly $13.1 million), aims to build a robust Bitcoin financial ecosystem in Japan, offering innovative products to retail investors.

The deal, anticipated to finalize on July 13, 2026, represents the inaugural major step under "Project Nova," Metaplanet's ambitious long-term plan. This initiative seeks to transform the company's substantial Bitcoin treasury into the foundation of a comprehensive financial services business. Upon completion, Siiibo Securities will be rebranded as Metaplanet Securities Inc.

Paving the Way for Retail Bitcoin Products

A key driver behind this acquisition is the Type I Financial Instruments Business Operator registration that Siiibo Securities holds. This crucial license is required under Japanese law to structure and distribute financial products directly to individual investors. By gaining this regulatory standing, combined with Siiibo's established customer base and online platform, Metaplanet is uniquely positioned to introduce a range of Bitcoin-linked investment opportunities to the Japanese market.

Siiibo Securities, founded in January 2019, has built a strong reputation through its online platform for private placement corporate bonds. This market segment, traditionally exclusive to institutional players and high-net-worth individuals, has seen Siiibo facilitate over 100 bond offerings for more than 40 issuers, establishing one of Japan's most extensive track records in retail corporate bonds. This expertise will be invaluable as Metaplanet ventures into new financial product offerings.

Strategic Vision and Synergies

Metaplanet, known as Japan's largest corporate Bitcoin holder, reported holding 40,177 BTC as of May 31, 2026, with a net asset value of 457.6 billion yen. This positions the company as the third-largest corporate Bitcoin holder globally and the largest in Asia, drawing comparisons to MicroStrategy's strategy in the United States. President and CEO Simon Gerovich emphasized that Metaplanet views Bitcoin not merely as a treasury asset but as the bedrock for future financial ecosystems. This vision underpins the company's "Project Nova" and its recent acquisition efforts, as seen in previous moves to bolster its Bitcoin strategy. Metaplanet has consistently expanded its Bitcoin strategy through such strategic acquisitions.

The acquisition is expected to unlock several core synergies:

• Expanded Distribution: Metaplanet plans to distribute Siiibo's existing bond products to its vast shareholder base of approximately 250,000 investors.
• New BTC-linked Products: Development and distribution of innovative Bitcoin-linked financial products, including BTC-linked bonds, through the Siiibo platform.
• Joint Underwriting: Collaboration with Metaplanet Ventures Inc. for joint underwriting of bond and digital securities issuances, specifically targeting venture companies within the cryptocurrency and decentralized finance sectors.
• Security Token Pilot: A pilot program is on the horizon for security tokens and other digitized financial instruments, pushing the boundaries of traditional finance.

Kazuki Komura, CEO of Siiibo Securities, expressed optimism that the combined strengths of both companies in finance, technology, and community engagement would foster unprecedented capital formation structures and investment experiences. The acquisition will be funded through existing cash reserves and borrowings, with an option to utilize Bitcoin-backed credit facilities providing up to $500 million in aggregate borrowing capacity. This move solidifies Metaplanet's commitment to pioneering a new era of Bitcoin-integrated finance in Japan, building on its prior efforts to boost Bitcoin financial products.
