Metaplanet Inc., listed on the Tokyo Stock Exchange, has revealed a strong acceleration in its corporate strategy regarding Bitcoin, reporting a year-to-date BTC Yield of 568.2% for 2025 and bringing total reserves to 35,102 BTC.

The communication highlights the company's aggressive accumulation approach, positioning it among the largest publicly declared corporate holders of Bitcoin in the world.

Metaplanet acquires more Bitcoin

The company acquired an additional 4,279 BTC in the fourth quarter of 2025, paying an average price of 16.33 million yen ($104,642) per coin, according to CEO Simon Gerovich.

This brings Metaplanet's total investment in Bitcoin to approximately 559.7 billion yen, with an average price of 15.95 million yen ($102,207) per BTC for the year.

Metaplanet's Bitcoin accumulation falls within its officially designated Bitcoin Treasury Operations, a strategic business line launched in December 2024.

Purchases are made through a combination of operating profits, capital markets activities, and Bitcoin-backed credit lines. This reflects a sophisticated treasury strategy integrating market timing, equity management, and corporate financing instruments.

In just the fourth quarter, the BTC Yield reached 11.9%, contributing steadily to annual performance, following prior quarters that recorded yields of 95.6%, 129.4%, and 33%.

The company's proprietary BTC Yield metric measures the change in Bitcoin holdings per fully diluted share, isolating the impact of dilution from new equity issuances. This gives investors a clear view of shareholder value increase from Bitcoin accumulation, rather than direct profitability.

BTC Gain and BTC ¥ Gain translate these holdings into quantitative metrics in both BTC and Japanese yen. This provides insight into the hypothetical value growth generated exclusively by the treasury strategy.

Metaplanet ranks 4th globally as corporate Bitcoin adoption accelerates despite market volatility.

Despite the stated yield, Bitcoin Treasuries data shows Metaplanet's portfolio is down 18.9% in market value. This reflects Bitcoin's price volatility over the year.

The company emphasizes that BTC Yield is a KPI, not a measure of realized profits or operational performance. It offers a perspective on strategic accumulation, rather than traditional financial returns.

Metaplanet now ranks as the fourth largest corporate holder of Bitcoin globally, after Strategy (672,497 BTC), MARA (53,250 BTC), and Twenty One Capital (43,514 BTC).

The adopted approach, combining disciplined accumulation, capital markets activities, and leveraged structures, highlights how companies in Japan and around the world are adopting Bitcoin as a treasury asset, balancing risk with a strategic positioning for potential upside.

The announcement strengthens the growing role of corporate treasuries in Bitcoin markets, where companies like Metaplanet are quietly accumulating significant positions, while using metrics such as BTC Yield to communicate strategy and results to shareholders.

However, despite the impressive declared yields, investors should distinguish between proprietary performance metrics and actual financial profits. This distinction is becoming increasingly important as institutional participation in Bitcoin grows globally.

With 35,102 BTC under management and a record BTC Yield, Metaplanet's silent accumulation strategy in 2025 positions it as a notable force in corporate Bitcoin adoption. This suggests that publicly traded companies are increasingly using crypto as a strategic treasury tool, rather than a speculative asset.
