Metaplanet to complete Siiibo Securities acquisition on July 13 and launch Bitcoin-focused brokerage

Metaplanet, the Tokyo-listed company that has essentially become Japan’s answer to MicroStrategy, is about to add “securities firm” to its resume. The company will finalize its acquisition of Siiibo Securities on July 13, rebranding it as Metaplanet Securities Inc. and creating what amounts to a Bitcoin-native brokerage inside one of the world’s most tightly regulated financial markets.

The deal is valued at approximately 2.1 billion yen, or roughly $13.1 million, for full ownership of Siiibo. For that price, Metaplanet gets something money can’t easily buy in Japan: a Type I Financial Instruments Business Operator license. That’s the regulatory golden ticket required to distribute investment products to the public in the country.

From Bitcoin treasury to Bitcoin bank

The company calls this initiative “Project Nova.” The goal is straightforward, even if the execution is anything but: create Bitcoin-linked investment products and sell them to Japanese investors through a fully regulated platform.

Planned offerings include yield-focused Bitcoin products, BTC-linked bonds, and tokenized securities. These would be distributed through the online securities infrastructure that comes with the Siiibo acquisition, targeting Metaplanet’s roughly 250,000 existing shareholders as an initial customer base.

As of May 31, Metaplanet holds 40,177 BTC, giving it a net asset value of approximately 457.6 billion yen. That makes it Japan’s largest corporate Bitcoin holder by a wide margin, and one of the largest globally.

CEO Simon Gerovich has described the acquisition as a pivotal step in the company’s broader plan to expand Bitcoin financial infrastructure in Japan.

Why Japan, why now

Japan is sitting on roughly $7.4 trillion in household savings, a figure that represents one of the deepest pools of retail capital on the planet. For decades, that money has largely sat in bank deposits earning next to nothing, a rational choice in a deflationary economy where cash gains purchasing power over time.

Japan has been transitioning from its long deflationary era into a period of actual inflation, which means those savings are now slowly losing value in real terms.

What this means for investors

The acquisition itself is modest in financial terms. Spending $13.1 million is barely a rounding error for a company with a Bitcoin treasury worth billions. What Metaplanet is really buying is distribution capability. Having a regulated securities license means the company can create and sell financial products that traditional Japanese investors can actually access through familiar channels.

There are real risks, though. Regulatory approval for specific products is not guaranteed just because you hold the right license. The Japanese Financial Services Agency maintains strict oversight of securities offerings, and Bitcoin-linked products will face scrutiny that conventional bonds do not. Product design, risk disclosure, and investor protection requirements could all slow the timeline from license holder to active product distributor.
