The filing, released Wednesday, shows the company now holds 30,823 Bitcoin in total.

Data from BitcoinTreasuries.NET indicates this places Metaplanet as the fourth-largest publicly listed corporate holder of Bitcoin, moving ahead of the Bitcoin Standard Treasury Company.

According to the disclosure, the purchase was executed at an average price of 17.39 million yen per coin (around $116,000), for a total expenditure of $600 million.

The company’s cumulative holdings are valued at roughly $3.6 billion, with an average acquisition cost of about $108,000 per Bitcoin.

Based on current market levels, the position reflects an unrealized gain of approximately 7.5%, BitcoinTreasuries.NET data shows.

Metaplanet began acquiring Bitcoin in April 2024 and has expanded its holdings at a comparatively fast pace among publicly traded firms.

The company also tracks a measure it refers to as “BTC Yield,” which reflects the change in Bitcoin per fully diluted share.

This figure reached 309.8% in late 2024 before stabilizing at 33% in 2025, indicating slower growth in Bitcoin exposure on a per-share basis.

Industry data shows that public companies together hold over 1 million Bitcoin, valued at about $116 billion, representing 4.7% of total supply.

Across public corporations, ETFs, governments, exchanges, and private entities, treasuries account for roughly 3.8 million Bitcoin, worth an estimated $442 billion.
