KEY FACTS: Metaplanet Inc., a Tokyo-based investment firm, has become the world’s fifth-largest corporate Bitcoin holder after acquiring 5,419 BTC for $633 million, bringing its total holdings to 25,555 BTC, valued at nearly $3 billion. This purchase, executed at an average price of $117,000 per Bitcoin, underscores Metaplanet’s aggressive “Bitcoin-first” strategy as a hedge against Japan’s economic challenges, including yen depreciation and inflation. The company’s stock rose 3.8% following the announcement but remains 30% below its monthly peak, reflecting market volatility. Metaplanet is also expanding through new subsidiaries in the U.S. and Japan, aiming to generate yield and strengthen its Bitcoin ecosystem, while a $1.44 billion share issuance plan signals further acquisitions.

Metaplanet Soars to Fifth Place Among Global Corporate Bitcoin Holders with $633 Million Acquisition
Metaplanet Inc., a Tokyo-based investment firm once known primarily for its ventures in hotel management and Web3 technologies, has catapulted itself into the upper echelons of global Bitcoin treasuries. The company announced on Monday a massive purchase of 5,419 Bitcoin (BTC), valued at approximately $633 million, propelling its total holdings to 25,555 BTC and securing its position as the world's fifth-largest corporate holder of the digital asset.
This acquisition, executed at an average price of 17,281,012 Japanese yen per Bitcoin, equivalent to about $117,000 based on prevailing exchange rates, marks yet another aggressive step in Metaplanet's "Bitcoin-first" strategy. According to data from BitcoinTreasuries.NET, a leading tracker of corporate cryptocurrency reserves, Metaplanet's stack now trails only industry giants like MicroStrategy, Marathon Digital Holdings, Tesla, and Hut 8 Mining. The move comes amid a volatile period for Bitcoin's price, which hovered around $112,500 at the time of the announcement, implying a modest paper loss of nearly 3.9% on the freshly acquired tranche.
For Metaplanet, this is a calculated bet on Bitcoin as a hedge against Japan's persistent economic headwinds. With the yen facing depreciation pressures and inflation eroding traditional savings, the company has positioned itself as a pioneer in corporate adoption within Asia's largest economy.
Metaplanet's journey into Bitcoin began in earnest earlier this year, but its trajectory has been nothing short of meteoric. Founded in 1999 as a hotel operator, the firm pivoted sharply toward blockchain and decentralized finance in the early 2020s, rebranding itself as a "Bitcoin Treasury Company" in April 2025. What started as a modest allocation has snowballed into a multi-billion-dollar portfolio, fueled by a combination of equity raises, strategic partnerships, and an unyielding commitment to accumulation.
The latest buy brings the value of Metaplanet's Bitcoin holdings to nearly $3 billion at current market prices, a staggering 43% increase from $2.1 billion just one month prior. This growth is even more impressive when viewed through the lens of the company's proprietary "Bitcoin yield" metric, which measures the percentage change in the ratio of total BTC per fully diluted share. From July 1 to September 22, this yield surged to an eye-popping 10.3%, highlighting the efficiency of Metaplanet's fundraising and deployment tactics.
Yet, for all its treasury triumphs, Metaplanet is not immune to the whims of the market. The company's shares, listed on the Tokyo Stock Exchange under the ticker 3350 and traded over-the-counter in the U.S. as MTPLF, rose a modest 3.8% on Monday following the news. The stock has plummeted more than 30% over the past month, closing at $4.09 per share. Year-to-date, shares are up nearly 78%, a respectable gain, but they remain well below the all-time high of $15.35 reached on May 21, 2025, during the height of the spring Bitcoin rally.
Analysts attribute this disconnect to broader market dynamics, including Bitcoin's recent consolidation phase and investor fatigue with high-beta plays. The pressure is palpable, as a sustained share price decline could crimp the firm's ability to raise capital for future acquisitions.
To counter these challenges, Metaplanet has been aggressively diversifying its operations beyond mere accumulation. Earlier this month, the company unveiled two key subsidiaries aimed at fortifying its Bitcoin ecosystem. First, Metaplanet Income Corp., a U.S.-based entity headquartered in Miami, Florida, was launched with an initial capital injection of $15 million. This venture is designed to generate yield from Bitcoin-related activities, such as lending and staking protocols, while tapping into America's burgeoning crypto infrastructure.
Complementing this is Bitcoin Japan Inc., a domestic arm focused on strengthening Metaplanet's foothold in its home market. With Japan slowly warming to digital assets, boosted by regulatory clarifications from the Financial Services Agency—the subsidiary will explore opportunities in Bitcoin education, custody services, and integration with traditional finance.
These initiatives are part of a "flywheel" strategy that Metaplanet hopes will sustain its growth. In a shareholder update earlier this year, the board secured approval for a $3.7 billion funding round tied explicitly to Bitcoin expansion. More immediately, the firm announced plans to issue 385 million new shares at a nearly 10% discount to current trading prices, potentially raising up to $1.44 billion. Proceeds are earmarked for further Bitcoin purchases, R&D in Web3 applications, and bolstering the new subsidiaries.
Metaplanet's rise resonates far beyond Tokyo's financial district. As the fifth-largest corporate Bitcoin holder, it joins a select club dominated by U.S. firms, challenging the narrative of American exceptionalism in crypto. MicroStrategy, led by Bitcoin evangelist Michael Saylor, still reigns supreme with over 250,000 BTC, but Metaplanet's aggressive pace, adding thousands of coins monthly, has narrowed the gap considerably.
