Metaplanet Doubles Down: Massive Q4 Bitcoin Buy Catapults Holdings to 35,102 BTC

Japan's "Asia's MicroStrategy" aggressively accumulates resumes.

Metaplanet Inc. declared a significant Q4 2025 Bitcoin purchase of 4,279 BTC for almost $451 million, purchased at an average price of $105,412 per coin. With a total investment of around $3.78 billion and an average acquisition cost of $107,606 per BTC, this brings the company's holdings to 35,102 BTC as of December 30, 2025.

Strategic Location and Finance

Following a short respite, the purchases started again with finance through a mix of equity offerings and Bitcoin-backed loans (pulling $230 million from a $500 million credit facility). Behind leaders such as Strategy (formerly MicroStrategy), MARA Holdings, and XXI, this aggressive strategy places Metaplanet as the fourth-biggest public firm Bitcoin holder worldwide. Viewing Bitcoin as a key treasury asset, the corporation aims to have 210,000 BTC by 2027.

Mixed Market Response Among Volatility

Following the announcement, Metaplanet's stock (TYO:3350) dropped about 8% to roughly 405 JPY despite the bold move, mirroring pressure on Bitcoin's price below $106,000 (trading around $87,000–$88,000 at the time). With unrealized portfolio losses nearing $520 million resulting from short-term instability, the company's multiple to net asset value (mNAV) fell from 1.17 to 1.03. Still, the tactic mirrors MicroStrategy's playbook stressing long-term belief above short-term market swings.
