Metaplanet acquires Siiibo Securities for $13M in Bitcoin platform push

Metaplanet's $13 million acquisition of a licensed brokerage marks its pivot from passive Bitcoin holder to active financial platform builder, targeting Japan's $14.6 trillion pool of dormant household savings.

Metaplanet, the Tokyo-listed company often called "Japan's MicroStrategy," acquired Siiibo Securities for 2.1 billion yen ($13 million) under a strategy it calls Project Nova, the company said July 24. The deal gives Metaplanet a licensed brokerage through which it can offer Bitcoin-linked investment products to Japanese retail investors, moving beyond its previous model of simply accumulating Bitcoin on its balance sheet.

"Japan has $14.6 trillion in household savings sitting in bank deposits earning near-zero interest, and we see an opportunity to offer those investors regulated Bitcoin exposure through familiar investment channels," Simon Gerovich, chief executive officer of Metaplanet, said.

The company currently holds 2,235 Bitcoin after its most recent purchase of 135 BTC for approximately $13 million. Metaplanet also has access to a $500 million Bitcoin-collateralized credit facility, which it plans to use for share buybacks and further Bitcoin accumulation. The Siiibo Securities acquisition is the first step in Project Nova, with the company aiming to generate revenue from fees on Bitcoin-linked products rather than relying solely on Bitcoin price appreciation.

Japan's crypto moment

The acquisition comes as Japan prepares to open its first spot Bitcoin exchange-traded funds. Analysis by XWIN estimates the market could accumulate $18.4 billion, or roughly 3 trillion yen, by fiscal 2028 — a figure that represents just 0.13% of Japanese household savings and 1% of the country's equity investment fund market. Three sources of capital are expected to drive inflows: retail investors using tax-advantaged NISA accounts, institutional investors such as pension funds, and domestic financial giants like SBI Holdings, which has proposed launching a dual Bitcoin and XRP ETF targeting 5 trillion yen in assets under management within three years.

Tax reform could accelerate adoption. The tax rate on crypto income is expected to be reduced from 55% to the standard 20%, removing a major barrier for Japanese retail investors. The National Business Pension Fund in Okayama has already allocated 1% of its assets to crypto, signaling early institutional interest.

The immediate question for Metaplanet is whether it can integrate Siiibo Securities smoothly and launch its first products without regulatory delays from Japan's Financial Services Agency. At 2,235 BTC, the company's treasury is meaningful but not massive relative to its ambitions. The $500 million credit facility suggests plans to grow that position aggressively, though leveraged Bitcoin accumulation carries risks during market downturns. If Tokyo avoids bureaucratic bottlenecks, Asia could gain a regulated crypto hub capable of competing with the U.S. market.
