TL;DR – Metaplanet Inc., a Japanese "Bitcoin Treasury Corporation," is raising ¥21.25 billion through 23.61 million Class B Preferred Shares to expand its Bitcoin holdings. This strategic funding approach minimizes common share dilution while offering 4.9% dividends and conversion rights, positioning Bitcoin as a hedge against global economic uncertainties.
In the rapidly evolving Bitcoin treasury landscape, Metaplanet Inc. (TSE Standard: 3350) is capturing attention with its latest funding initiative. If you're wondering "what is metaplanet" or "what does metaplanet do," this Japanese company has transformed from traditional operations into a Bitcoin-focused entity, strategically accumulating BTC as a core asset. At 21Rates, we provide comparisons of Bitcoin lending, ETFs, and custody services to help investors navigate similar strategies.
The announcement details a third-party allotment of Class B Preferred Shares to overseas allottees, subject to approval at the December 22, 2025, Extraordinary General Meeting. Priced at ¥900 per share, the raise totals ¥21.249 billion and is aimed at accelerating Bitcoin acquisitions under plans such as the "21 Million Plan" and "555 Million Plan."
This comes amid market corrections, during which Metaplanet's stock dipped below its mNAV, prompting a Capital Allocation Policy that emphasizes preferred equity to optimize funding.
Metaplanet views Bitcoin as a superior store of value due to its scarcity, utility, and transparency, positioning it against rising geopolitical risks and sovereign debt concerns. With BTC holdings now central to its value, the firm has generated significant income from Bitcoin-related activities. For more on corporate BTC adoption, check our Bitcoin Treasury Companies guide.
What Is Metaplanet and What Does Metaplanet Do?
Initially focused on global economic transitions, Metaplanet repositioned in April 2024 as a "Bitcoin Treasury Corporation." It holds BTC long-term on its balance sheet, using derivatives and financing to expand holdings. By Q3 2025, Bitcoin income reached billions in yen, creating a reinvestment cycle.
This shift aligns with viewing BTC as a hedge against inflation and currency risks, distinguishing it from traditional assets.
The Class B Shares are non-voting, with a ¥1,000 liquidation preference and quarterly dividends at 4.9% annually (¥12.25 per share per record date, pro-rated for Q4 2025). They prioritize dividends over common shares but are subordinate to Class A. For secure BTC management post-investment, explore our Best Bitcoin Custody Services.

Key Features Include:
- Conversion Rights: Holders can convert to common shares at ¥1,000 (adjustable), potentially adding up to 2.07% dilution if fully exercised
- Redemption Options: Cash redemption if not listed on TSE by December 2026, or upon events like reorganizations
- Company Calls: Acquirable if trading above 130% of preference for 20 days (after 10 years) or if value falls below ¥6 billion
