Metaplanet Inc., Japan’s leading corporate Bitcoin holder, has added another 1,005 BTC to its treasury, further deepening its commitment to the digital asset. As disclosed on June 30, the company spent ¥15.648 billion (approximately $108 million) on the latest purchase, acquiring Bitcoin at an average price of ¥15,569,831 (roughly $107,430) per coin. This raises Metaplanet’s total holdings to 13,350 BTC, accumulated at an average cost of ¥14,331,959 (around $98,891) per BTC.
To fund future acquisitions, Metaplanet also announced the issuance of its 19th series of ordinary bonds, worth ¥30 billion (about $207 million), to EVO FUND. These bonds, which carry zero interest, are set to mature in December 2025. The proceeds will be used both to expand Bitcoin reserves and refinance ¥1.75 billion in secured debt from its third bond series issued in November 2024.
The company also released updated performance metrics related to its Bitcoin-focused strategy. Its BTC Yield—a key indicator reflecting the increase in Bitcoin value per share—jumped from 95.6% in the previous quarter to 129.4% between April and June 2025.
Metaplanet’s aggressive expansion aligns with its “555 Million Plan,” unveiled earlier in June, which targets ¥555 billion (approximately $5.4 billion) in capital to acquire 210,000 BTC by 2027—equivalent to 1% of Bitcoin’s total supply. The company has ramped up acquisitions throughout June, including 1,112 BTC on June 16, 1,111 BTC on June 23, and 1,234 BTC on June 26.
Despite soaring share prices and growing institutional backing, Metaplanet remains Japan’s most shorted stock, highlighting ongoing market skepticism about its Bitcoin-centric approach. Nonetheless, the company now holds the title of Asia’s largest corporate Bitcoin holder, following in the footsteps of U.S.-based MicroStrategy.
