Tokyo-listed Metaplanet has quietly climbed into the ranks of the world’s largest corporate Bitcoin holders. The company confirmed this week that its reserves have topped 20,000 BTC, making it the first non-U.S. firm to break into the global top six.
Metaplanet’s Latest Bitcoin Buy
In a filing Monday, Metaplanet disclosed the purchase of an additional 1,009 BTC for roughly $112 million, paying an average of $111,000 per coin. The move comes just a week after it picked up 103 BTC, underscoring an aggressive accumulation strategy.
With this latest purchase, Metaplanet’s total stash now exceeds 20,000 BTC, acquired at a combined cost of $2.06 billion (¥302.3 billion). Data from BitcoinTreasuries.net shows the company has now leapfrogged U.S. mining firm Riot Platforms, strengthening its position among corporate heavyweights like MicroStrategy and Marathon Digital.
Strategy: Bitcoin at the Core
For the third quarter of 2025, Metaplanet reported a BTC Yield of 30.7%, a metric that reflects growth in Bitcoin holdings relative to its fully diluted share count. In other words, shareholder value is directly linked to the company’s Bitcoin balance sheet.
The Japanese firm has been financing its buys through a mix of stock offerings and debt restructuring. In August, it issued its 20th round of stock options to EVO FUND, creating 60 million new shares. The capital went toward Bitcoin purchases and early repayment of corporate bonds.
Market Reaction
Despite the scale of the acquisition, the stock market didn’t reward the move. On announcement day, Metaplanet shares closed at ¥831, down 5.46% from the previous session. That muted response highlights the divide between traditional equity investors and the crypto community, where the firm’s bold strategy is earning it recognition as a pioneer.
Why It Matters
Metaplanet’s rise signals a shift in Bitcoin corporate adoption, which has so far been dominated by U.S. companies. As Asia’s most aggressive Bitcoin treasury holder, Metaplanet is setting a precedent for other listed firms in the region.
The company says it will continue building its Bitcoin reserves in line with “capital strategy and market conditions.” For investors, that means the Tokyo-based firm is betting its long-term future squarely on Bitcoin’s role as a reserve asset.
