Japan’s Bitcoin investment leader, Metaplanet, has reported a remarkable surge in its stock trading volume during June, reflecting a continuous escalation in its Bitcoin holdings.
As per data from Reuters, Metaplanet’s trading volume leaped to 1.86 trillion yen (approximately $12.87 billion) in June, nearly doubling the 997.6 billion yen ($6.82 billion) recorded in May, according to statistics from the Tokyo Stock Exchange.
This notable trading activity positioned Metaplanet ahead of automotive giant Toyota and technology titan Sony on the prime market, with only Advantest surpassing its volume.
The company has maintained its leading status since November of the previous year, emphasizing its innovative approach as the former hotel operator transitioned to a Bitcoin acquisition entity, now recognized as the fifth-largest corporate Bitcoin buyer globally.
Metaplanet’s shares, listed on the Tokyo exchange, have experienced an astounding rise of over 345% this year, following a strategic transformation to operate as a Bitcoin treasury firm in 2024.

Japanese Bond Market Chaos: Investors Turn to Metaplanet Due to Transparency
According to Metaplanet’s official website, the firm currently holds 15,555 Bitcoin, valued at approximately $1.69 billion as of the latest updates.
With Japan’s 30-year government bond prices plummeting by 45% since 2019, many investors are shifting their focus to Metaplanet, considering it a viable Bitcoin proxy amid the instability of fixed-income markets.
Experts have indicated that despite the current price rally, Metaplanet’s market net asset value (mNAV) is seen as reasonable and still possesses potential for further growth.
Furthermore, Metaplanet has distinguished itself by ensuring transparency through the provision of Proof of Reserves for its Bitcoin assets, a practice that sets it apart from its competitors. Simon Gerovich, the company CEO, has made public on-chain verification of their BTC holdings.
This transparency contrasts sharply with that of Strategy’s CEO, Michael Saylor, the largest holder of corporate Bitcoin, who has recently dismissed on-chain proof of reserves as a “bad idea” that could introduce security vulnerabilities.
In a recent announcement, Metaplanet disclosed its acquisition of 2,205 Bitcoin, underlining its aggressive strategy to build its cryptocurrency portfolio.
Since early 2025, the company’s holdings have skyrocketed from 4,000 BTC in March to over 15,500 BTC in July, marking a remarkable fourfold increase within just four months.
Crypto Community Raise Concerns Over Corporate BTC Treasury Strategy
Nonetheless, skepticism persists within the cryptocurrency community regarding the sustainability of the escalating Bitcoin treasury trend. Matthew Sigel, head of digital asset research at VanEck, expressed concerns that firms holding BTC may be on unstable footing, as increasing pressures could jeopardize shareholder value.

Moreover, Glassnode’s lead analyst, James Check, has voiced apprehensions regarding the longevity of corporate Bitcoin treasury strategies, arguing that these entities might not last as long as many anticipate.
“It’s about how serious & sustainable your product & strategy is to sustain the accumulation,” he remarked in a recent post on X.
