Metaplanet Inc., a leading Japanese bitcoin treasury firm, has continued to expand its Bitcoin holdings, announcing another large purchase. On September 22, the firm purchased 5,419 Bitcoin (BTC) at an average price of approximately 17.28 million yen each ($116,724), spending a total of roughly 93.6 billion yen ($632.53M).
According to Metaplanet’s official announcement, the company’s total stash has reached 25,555 BTC, acquired at an average cost of approximately 15.58 million yen (around $106,065) per coin. Altogether, the company has invested close to 398.2 billion yen (about $2.71B) in Bitcoin.
At the time of writing, Bitcoin was trading at around $114,575, according to CoinMarketCap. This puts the value of Metaplanet’s Bitcoin holdings at approximately $2.93 billion based on current market prices.Â
This latest purchase comes after the company made a smaller buy, adding just 136 BTC to its holdings on September 18, 2025. With this, Metaplanet has now crossed 85% of its 2025 target of accumulating 30,000 BTC.Â
Metaplanet has also been tracking a set of in-house performance measures it calls BTC Yield, BTC Gain, and BTC ¥ Gain. From July 1 to September 22, 2025, Metaplanet reported a BTC Yield of 10.3%, following significantly higher yields in previous quarters.
Recent share offering
Metaplanet has been active in the capital markets to fund its Bitcoin purchases. Since July, it has redeemed portions of previously issued bonds and raised money through the exercise of stock acquisition rights.
Earlier this month, the company issued 385 million new shares in an international offering, raising about $1.4B (≈205 billion yen). Most of the proceeds, around 183.7 billion yen, have been allocated for Bitcoin purchases over the next two months. Nearly half of that amount has already been deployed.
Metaplanet began treating Bitcoin as an official business line in late 2024. Since then, it has steadily scaled up its holdings through a combination of equity fundraising and bond activity.
According to Yahoo Finance, Metaplanet’s stock price closed at 597, down ¥11 or 1.65% in Tokyo trading.
