Metaplanet's Largest Bitcoin Purchase Moves It Into the Top Tier of Public Holders
Metaplanet announced the purchase of 5,419 BTC, its largest acquisition to date, raising holdings to 25,555 BTC and moving the Japanese company into roughly fifth place among public corporate Bitcoin holders.
On September 22, 2025, Tokyo-listed Metaplanet announced that it had acquired 5,419 BTC, its largest single Bitcoin purchase to that point. The acquisition cost roughly $632 million at the exchange rates reported contemporaneously and increased the company's holdings to 25,555 BTC.
Metaplanet had already become one of the most aggressive adopters of the Bitcoin-treasury model outside the United States. The September purchase mattered because it crossed a scale threshold rather than merely adding another recurring transaction. Contemporary rankings placed the company around fifth among publicly traded corporate Bitcoin holders, making it one of the largest corporate holders in the world and the most prominent Asian example of the strategy.
The event illustrates how the corporate Bitcoin-treasury phenomenon was becoming geographically broader and more concentrated at the same time. A model pioneered by Strategy was no longer a U.S.-only experiment: a Japanese public company had accumulated tens of thousands of Bitcoin and moved into the same global rankings as much larger Western firms.
