Metaplanet Boosts Bitcoin Reserves to 18,113 BTC After New Purchase
Metaplanet Inc., often referred to as "Japan’s MicroStrategy," has announced another major addition to its Bitcoin treasury, acquiring an extra 518 BTC.
The purchase, disclosed on August 12, 2025, pushes the company’s total Bitcoin holdings to 18,113 BTC.
This marks a sharp increase from the 17,595 BTC the company held just days earlier, continuing an aggressive accumulation strategy that began in 2024.
Largest Corporate BTC Holder in Japan
With this purchase, Metaplanet cements its position as the largest corporate Bitcoin holder in Japan and one of the top publicly traded Bitcoin treasuries globally. The company’s total BTC acquisition cost stands at 274.93 billion yen (~$1.86 billion), highlighting its long-term conviction in Bitcoin as a strategic reserve asset.
“Alchemy of 5%” Goal
Metaplanet has publicly stated its ambition to acquire 5% of all Bitcoin in circulation – a target that, if achieved, would require roughly 1 million BTC. While still far from that figure, the pace of accumulation has accelerated significantly, with the company adding billions of yen worth of Bitcoin in recent months.
Institutional Support and Liquidity Strength
The firm’s buying spree has been backed by a roster of heavyweight investors, including ARK Invest’s Cathie Wood, Founders Fund, Pantera Capital, Kraken, and Galaxy Digital. Metaplanet is also among the most liquid stocks in the U.S. market, ranking 25th in average daily dollar trading volume at $2.2 billion, surpassing giants like JPMorgan and Micron Technology.
With its aggressive treasury strategy, deep institutional support, and high trading liquidity, Metaplanet continues to position itself as a leading corporate force in Bitcoin adoption – and its latest purchase signals no slowdown in its accumulation plans.
