Metaplanet buys a securities license to sell Bitcoin yield to Japan

Japan's largest corporate Bitcoin holder wants to become Japan's Bitcoin bank. @Metaplanet announced on June 12 that it has agreed to acquire 100% of licensed broker @siiibo Securities for 2.1 billion yen (approximately $13 million), with plans to rebrand the firm as Metaplanet Securities and use it to distribute $BTC-linked yield products directly to retail investors.

The deal is expected to close on July 13, 2026. It marks the company's first major merger and acquisition and the opening move of what CEO Simon @gerovich calls Project Nova, a long-term strategy to build a Bitcoin-centric financial ecosystem in Japan.

What Metaplanet Is Actually Buying

The acquisition is as much about regulatory access as it is about the business itself. Siiibo holds a Type I Financial Instruments Business registration, the license Japanese firms need to structure and distribute securities to retail investors. By acquiring an active Type I licensed entity, Metaplanet effectively bypasses the lengthy process of obtaining regulatory approval from Japan's Financial Services Agency from scratch.

Founded in 2019, Siiibo pioneered Japan's online corporate bond market, backing more than 40 issuers and facilitating over 100 bond offerings. Despite that track record, the firm has not turned a profit, losing between 159 million and 175 million yen in each of its last three fiscal years. Metaplanet's own filing suggests the acquisition price largely reflects what obtaining a fresh registration would cost in time, capital, and compliance staffing.

Planned products include BTC-linked bonds, treasury-backed preferred shares, and security tokens, all subject to regulatory clearance. Metaplanet also plans to distribute Siiibo's existing bond products to its shareholder base of approximately 250,000 investors.

Targeting Japan's $7.4 Trillion Savings Pool

The strategic logic behind the deal rests on a shift in Japan's macroeconomic environment. Gerovich noted that Japanese households hold roughly $7.4 trillion in cash, deposits, and low-yield products, and that as Japan moves from deflation to inflation, that capital has begun searching for yield. Metaplanet wants to be where it lands.

Metaplanet held 40,177 $BTC as of May 31, 2026, with a net asset value of 457.6 billion yen, making it the third-largest corporate Bitcoin holder in the world and the largest in Asia. Project Nova represents the next phase: converting that treasury into the backbone of a financial services business.

Metaplanet said it will fund the acquisition from cash on hand and borrowings, with the option to draw on Bitcoin-backed credit facilities carrying an aggregate borrowing capacity of up to $500 million. Execution risks remain. Integrating a traditional securities firm into a crypto-native corporate structure presents operational challenges, and the inherent volatility of Bitcoin as collateral means its ambitious targets will require careful risk management.
