One of Tokyo’s main financial regulatory authorities—Japan Exchange Group—has taken note of the increase of crypto treasury companies using Bitcoin as its main reserve asset and is considering tightening rules to curb the rapid growth of the industry, as per a Bloomberg Japan report.
According to one person who spoke to Bloomberg Japan, the new regulations being considered were preventing ‘backdoor listings’ and mandatory audits for these companies.

Metaplanet has responded to the Bloomberg report via an official company notice saying
“In recent years, there has been a global increase in the number of “Bitcoin treasury companies” that hold Bitcoin as a corporate reserve asset. In line with this trend, we understand that regulatory discussions are progressing in various jurisdictions with the aim of ensuring investor protection and maintaining market integrity, particularly with respect to preventing backdoor listings and strengthening corporate governance.”
“We believe this is a natural and healthy development that will contribute to enhancing the transparency and credibility of this emerging business model,” it also read.
