Japan’s Metaplanet Expands Bitcoin Treasury With 518 BTC Purchase, Stock Reacts

Japan’s Metaplanet Inc. has expanded its Bitcoin treasury, announcing the purchase of 518 BTC. This establishes the business as one of the most notable Bitcoin corporate owners.

Metaplanet Increases Bitcoin Treasury With New Purchase

Metaplanet added to its Bitcoin treasury with the purchase of 518 BTC valued at approximately $61.4 million. The acquisition was made at an average price of $118,519 per coin.

The August 12 transaction brings Metaplanet’s total Bitcoin holdings to 18,113 BTC, acquired for roughly $1.85 billion at an average cost of $101,911 per coin. In yen terms, the latest purchase amounted to 9.086 billion yen, with an average purchase price of 17,540,861 yen per Bitcoin. 

The firm’s current aggregate Bitcoin investment stands at 270.364 billion yen, reflecting the scale of its commitment to the cryptocurrency. 

The acquisition follows another significant buy in late July, when Metaplanet added 463 BTC to its reserves at an average price of $115,895, totaling $53.7 million. That purchase took its holdings at the time to 17,595 BTC, worth approximately $1.78 billion, and delivered a 459.2% YTD Bitcoin yield.

The company’s rapid pace of accumulation echoes moves from other Bitcoin-focused entities such as Strategy, which recently disclosed the purchase of 155 BTC for $18 million at an average of $116,401 per coin. Strategy’s holdings now stand at 628,946 BTC, valued at $46.09 billion.

According to analysts, these concentrated corporate purchases might be a sign of an increasing institutional interest in Bitcoin, especially among companies that are adopting a “Bitcoin standard” approach to treasury management.

Market and Stock Reaction

Following the announcement, Metaplanet’s stock experienced a brief 1% uptick, rising from 985 yen to 997 yen before crashing back to 980 yen. 

Meanwhile, Bitcoin’s market price saw little immediate impact. The cryptocurrency slipped about 2% to $119,000. It eased from recent highs that had brought it within striking distance of its all-time high.

Given Metaplanet’s established pattern of frequent purchases, traders observe that the market may have partially priced in the acquisition based on the muted reaction in the spot price of Bitcoin.

Metaplanet’s latest move comes on the back of an already stellar performance in 2025. From July 1 to August 12, Metaplanet achieved a Bitcoin yield of 26.5%. This has increased its year-to-date performance to an impressive 468.1%.

By continuously acquiring Bitcoin, Metaplanet follows a careful buying strategy, regardless of short-term market changes. Many institutional investors believe that Bitcoin is a good way to protect against inflation and serves as a long-term investment.

With control of 18,113 BTC, the Tokyo-listed company is now one of the largest corporate holders of Bitcoin globally. This strategy could pay off well if Bitcoin reaches its previous all-time highs in the coming weeks.
