Metaplanet Inc., a Tokyo-based company, has accelerated its Bitcoin acquisition strategy, purchasing 136 BTC for $15.3 million. Based on the firm’s average acquisition cost, this brings its total holdings to 20,136 BTC, valued at roughly $2.07 billion. Over the past ten weeks, Metaplanet has consistently purchased Bitcoin on a weekly basis, executing ten separate acquisitions totaling 7,791 BTC.

The company has consistently emphasized that Bitcoin is a strategic reserve asset, part of a long-term balance sheet diversification policy designed to strengthen shareholder value. Its treasury performance metrics highlight the impact of this approach. From July 1 through September 8, Metaplanet reported a Bitcoin yield of 30.8%. Previous quarters recorded yields of 129.4% in Q2 2025, 95.6% in Q1 2025, and an extraordinary 309.8% in Q4 2024.

Yield is calculated by comparing total BTC holdings to fully diluted outstanding shares relative to earlier baseline periods. The company also tracks “BTC Gain,” which isolates net Bitcoin accumulation from financial strategy while excluding dilutive effects. Metaplanet’s cumulative BTC Yen Gain for the current quarter reached $458 million, calculated using a reference price published on Japanese exchange Bitflyer.

Metaplanet has funded these acquisitions by exercising warrants and redeeming bonds, maintaining what it describes as a disciplined, systematic approach. Analysts note this places the company among Asia’s largest corporate Bitcoin holders.

Convano: First Step of 21,000 Bitcoin Plan

Convano Inc., a beauty and retail services group best known for its nail salon chains, announced an ambitious plan to purchase Bitcoin worth $136 million by November 2025. The investment will be financed through proceeds from its Fifth Ordinary Bond issuance.

The acquisition represents the first phase of Convano’s “21,000 Bitcoin Financial Complement Plan,” which aims to hold 21,000 BTC—equivalent to 0.10% of the total supply—by March 2027. With a $17 million purchase plan approved earlier this month, Convano’s total commitment now exceeds $213 million.

Management positions Bitcoin as a key “store of value” within its corporate treasury, seeking protection against yen depreciation and inflation risks. The company also emphasized strategic considerations beyond hedging, including shareholder value enhancement, capital policy consistency, and building a distinctive digital-asset brand identity.

Convano argues that stronger institutional investor participation has improved market liquidity and price discovery, creating favorable conditions for large-scale corporate entries. Its initiative marks one of the most significant crypto commitments within Japan’s beauty and retail industries.

Broader Implications for Japanese Corporate Treasury Strategy

The two announcements highlight shifting corporate attitudes in Japan toward Bitcoin as a treasury asset. Persistent low interest rates and exchange-rate volatility have prompted some businesses to explore digital assets as an alternative to cash holdings.

Metaplanet’s stock price has soared over 1,700% since adopting its Bitcoin-focused strategy, though the company cautions that multiple factors beyond digital assets influence equity markets. Convano’s entry illustrates how non-financial firms also integrate cryptocurrency into capital planning.

Analysts suggest these moves may accelerate broader adoption across Japanese corporates with large cash reserves. Early adopters’ success could encourage traditional businesses to view Bitcoin as a viable reserve asset rather than a speculative instrument.
