Japan Exchange Group is evaluating changes to oversight for listed companies that accumulate large cryptocurrency reserves, according to sources cited by Bloomberg.
The Tokyo-based exchange operator has not confirmed the proposals but continues its internal assessment, the sources added.
Officials are reviewing audit and listing rules that may affect companies shifting business toward digital asset accumulation.
Japan May Audit Crypto-Heavy Listed Firms
Japan Exchange Group may introduce audits for firms with increased exposure to cryptocurrencies, people familiar with the matter said.
The review would target firms that are adjusting their operations to focus heavily on digital asset holdings, according to those same individuals.
The group has not finalized any rule changes, but discussions among senior officials remain active.
Companies shifting toward crypto accumulation could trigger audit reviews, aligning with tighter compliance standards, sources said.
Such audits may assess whether the firm’s operations have materially changed from their original business models.
Japan’s financial authorities have not publicly commented on the exchange’s ongoing review.
Backdoor Listing Scrutiny Intensifies
Japan’s stock exchange may apply tighter interpretations of its backdoor listing regulations for crypto-focused companies, sources disclosed.
This approach could affect firms using listed status to pivot into large-scale crypto reserve holdings.
Such interpretations would evaluate whether businesses are trying to sidestep formal listing disclosures.
The Japan Exchange Group aims to preserve transparency in market operations through existing and, if necessary, revised frameworks.
Three companies reportedly received informal warnings related to their digital asset acquisition strategies.
Each firm subsequently paused crypto accumulation, citing potential impacts on fundraising capacity.
Metaplanet Holds Bitcoin, Faces No Regulatory Action
Tokyo-listed Metaplanet began acquiring bitcoin in April 2024 and has amassed 30,823 bitcoin to date.
It is now the fourth-largest publicly traded corporate bitcoin holder globally, according to the company’s data.
Metaplanet confirmed no regulatory sanctions or restrictions have been imposed on its operations.
The company said, “We continue to follow all legal and corporate governance procedures as required under Japan law.”
Japan’s current rules do not prevent listed firms from purchasing or holding crypto assets.
However, market regulators are now reviewing whether new oversight may be needed to address digital asset risks.
