Metaplanet has agreed to acquire all shares of Siiibo Securities Co., Ltd., expanding its push beyond corporate Bitcoin accumulation and into regulated financial services. Following the July closing, the Tokyo-listed firm plans to rename the business Metaplanet Securities Co., Ltd.
The Bitcoin news marks Metaplanet’s first full-scale acquisition and provides direct access to Japan’s regulated securities market. The company intends to use that foundation to develop Bitcoin-linked investment products and broaden its financial ecosystem under Project Nova.
Metaplanet CEO Simon Gerovich said the company had reached an agreement to buy 100% of Siiibo Securities. Siiibo operates as a Type I Financial Instruments Business Operator in Japan. The firm also runs an online platform that serves individual investors in the corporate bond market.
Metaplanet plans to use the acquired business as a licensed base for new Bitcoin-related financial products. After the closing, the company plans to change Siiibo’s trade name to Metaplanet Securities Co., Ltd. The Bitcoin news gives Metaplanet a direct route into Japan’s regulated securities market.

The deal forms the first concrete step in Project Nova, according to the Bitcoin news. Project Nova focuses on building a financial platform around Bitcoin, securities products, and investor demand for yield. Metaplanet has framed the acquisition as part of its wider plan to move beyond treasury holdings.
Metaplanet said Siiibo’s license and online platform will help it offer Bitcoin-related yield products in Japan. The Bitcoin news plans to combine Siiibo’s securities infrastructure with its own Bitcoin treasury position. This structure may allow the firm to create regulated products linked to Bitcoin exposure.
The company also pointed to changing household investment behavior in Japan. Gerovich said about 1,190 trillion yen remains held in cash deposits and low-yield products among Japanese households. Metaplanet sees this pool of capital as a target market for new yield options.
Japan’s move from deflation toward inflation has pushed more investors to look for returns. Metaplanet said that the shift creates demand for products that offer alternatives to low-yield savings. The company plans to serve that demand through the renamed Metaplanet Securities.
Metaplanet said it holds 40,177 BTC, making it Asia’s largest corporate Bitcoin holder. The company has used its Bitcoin treasury strategy as the base of its public market identity. The Siiibo deal now adds a securities business to that strategy.
The company did not announce a fresh Bitcoin purchase with this acquisition. However, the deal shows that Metaplanet wants to build services around its existing Bitcoin position. Its next stage now includes product distribution, not only balance sheet growth.
Earlier this year, Metaplanet issued $50 million in bonds to buy more Bitcoin. That fundraising showed the company’s continued interest in expanding its BTC holdings. The Siiibo acquisition adds another layer by focusing on investor products and securities access.
Gerovich praised Siiibo founder Kazuki Komura and the firm’s team for building a recognized platform in Japan’s corporate bond market. Metaplanet plans to leverage that foundation as it develops new financial products for domestic investors.
The acquisition also positions the company to participate more directly in Japan’s evolving investment market, where rising inflation has increased interest in alternatives to traditional savings accounts.
Investors will now focus on two milestones: completion of the July acquisition and the first Bitcoin-linked products launched through Metaplanet Securities.
If successful, the transaction could transform Metaplanet from a Bitcoin treasury company into a broader digital asset financial services provider operating within Japan’s regulated market framework.
