Metaplanet’s stock trading volume nearly doubled in June 2025, reaching approximately $11.6 billion, as the company ramped up its Bitcoin treasury strategy—surpassing major Japanese corporations like Toyota Motor and Sony Group.
According to data from the Tokyo Stock Exchange, the Tokyo-based investment firm recorded a trading volume of 1.87 trillion yen (around $11.6 billion) in June, marking an 87% increase from May’s 997.6 billion yen.
This surge propelled Metaplanet ahead of industry titans Toyota and Sony, whose trading volumes in June stood at 1.6 trillion yen and 1.3 trillion yen, respectively. However, Advantest retained the top spot with a trading volume of 4.8 trillion yen.
As reported by Reuters Japan, Metaplanet’s share price began climbing in mid-June, driven by growing investor interest in its expanding Bitcoin strategy. On June 16, the company’s stock closed at a high of $1.895—up 25% from $1.509 just the day before.
On June 16, Metaplanet reached a major milestone by surpassing 10,000 BTC in its treasury, just hours after announcing its ambitious goal to accumulate up to 210,000 BTC by 2027. That day, the company acquired 1,112 BTC, pushing its total holdings to the 10,000 BTC mark.
Over the course of June, Metaplanet executed five separate Bitcoin purchases, the most recent of which took place on June 29—adding 1,005 BTC following a $207 million issuance in ordinary bonds. With another purchase completed on July 7, the company’s total Bitcoin holdings have now climbed to 15,555 BTC.
At current market value, Metaplanet’s Bitcoin reserves are worth approximately $1.68 billion.
Metaplanet’s 210k BTC strategy
On June 6, Tokyo-based investment firm Metaplanet unveiled plans to significantly expand its Bitcoin holdings as part of its ongoing Bitcoin treasury strategy, inspired largely by Michael Saylor’s approach. The company has set an ambitious target: to acquire 210,000 BTC by 2027.
This target represents 1% of the total global Bitcoin supply. To achieve it, Metaplanet has raised its BTC accumulation goal for 2026 from 21,000 BTC to 100,000 BTC. By the end of 2025, the firm plans to more than triple its holdings—from 8,888 BTC in early June to 30,000 BTC.
Metaplanet began accumulating Bitcoin in May 2024 as a hedge against inflation and the declining value of the Japanese yen. Since November 2024, the company has consistently ranked as the top-traded firm on the Tokyo Stock Exchange’s standard market, with Nomura Shipbuilding trailing in second place with 516 billion yen in trading volume.
