Japanese Bitcoin treasury company Metaplanet signed a 2.1 billion yen ($13.11 million) agreement to acquire Siiibo Securities. The deal allows the corporate accumulator to transition into a financial distributor, packaging Bitcoin-backed yield products for retail investors. The acquisition occurs as Japan exits decades of stagflation and ultralow interest rates, generating domestic retail demand for higher-yielding financial products.
The transaction is scheduled to close on July 13, 2026. Siiibo Securities will undergo a formal rebranding to Metaplanet Securities by the end of August. Metaplanet currently holds 40,177 Bitcoin in its corporate treasury, valued at approximately $2.6 billion. Siiibo brings established infrastructure to the acquisition, having previously facilitated over 100 corporate bond offerings for more than 40 companies on its platform.
The acquisition utilizes Siiibo’s existing Type 1 Financial Instruments Business license to legally distribute Bitcoin-linked bonds within the country. Metaplanet will fund the purchase through a combination of corporate cash and debt, potentially utilizing a $500 million Bitcoin-collateralized credit facility to finalize the transaction. This marks the opening phase of an internal strategy titled “Project Nova,” designed to build a broader financial ecosystem around the company’s cryptocurrency reserves.
What Japan’s Proposed Crypto Tax Revisions Mean for Metaplanet
The Siiibo acquisition positions Metaplanet ahead of impending regulatory shifts in the Japanese domestic market. Lawmakers are advancing proposed revisions to the Financial Instruments and Exchange Act. These legislative changes aim to reduce the maximum capital gains tax on cryptocurrency from 55% down to a flat 20% by 2028.
This tax parity aligns digital assets with traditional Japanese stocks and bonds. Market analysts anticipate that digital-asset treasuries like Metaplanet will soon face direct competition from traditional exchange-traded fund providers as Tokyo regulates the cryptocurrency sector more similarly to conventional equity markets.
