Japan Exchange Group Considers Stricter Oversight of Crypto-Holding Firms Amid Market Volatility

Japan Exchange Group (JPX), the operator of the Tokyo Stock Exchange, is weighing tighter regulations for listed companies that hold significant cryptocurrency reserves, according to a Bloomberg report. The move follows growing concern over the risks and market swings tied to digital asset treasury (DAT) strategies.

Sources familiar with the matter said JPX is exploring several options, including stricter interpretations of existing backdoor-listing rules and possible requirements for fresh audits when a company shifts its focus toward large-scale crypto accumulation. Backdoor listings—where a private company goes public through a merger or acquisition rather than an initial public offering—are already prohibited. JPX may extend this restriction to prevent listed firms from pivoting their business models primarily toward cryptocurrency holdings.

While no formal decision has been made, the report notes that at least three publicly traded companies have paused plans to start buying digital assets after discussions with the exchange. JPX reportedly cautioned them that heavy crypto exposure could impact their ability to raise funds in the future.

Currently, there are no explicit rules barring Japanese listed companies from holding cryptocurrencies as part of their treasury assets. JPX has not issued an official statement in response to the report.

Market Reaction and Industry Context

The potential policy shift comes as shares of Japan’s crypto-treasury firms face steep declines. Metaplanet, a Tokyo-listed company that adopted a bitcoin accumulation strategy in April 2024, has seen its stock price fall more than 79% from its June peak—dropping from 1,895 yen to 397 yen ($2.60) as of Thursday. Despite the downturn, Metaplanet emphasized that it remains in full compliance with corporate governance and legal requirements.

“With shareholder approval at both extraordinary and annual general meetings, we have adhered to all procedures deemed necessary under applicable laws and regulations, maintaining corporate governance as our highest priority,” the company said in a statement.

Other DAT-related stocks were also hit hard. Shares of Convano Inc. fell 11.5%, while Bitcoin Japan Corporation dropped 16.2% on Thursday.

A Balancing Act for Regulators

JPX’s deliberations highlight Japan’s cautious stance toward digital assets—a sector that continues to draw both institutional interest and regulatory scrutiny. As companies increasingly explore bitcoin and other cryptocurrencies as treasury assets, Japan’s financial authorities face the challenge of supporting innovation while safeguarding investor confidence and market stability.
