Japan’s FSA Warned Binance Over Unregistered Crypto-Exchange Activity

Japan’s Financial Services Agency issued a formal warning to Binance Holdings Limited on June 25, 2021, saying the company had conducted crypto-asset exchange business with Japanese residents over the internet without registration.

The one-page notice identified Changpeng Zhao as the company’s representative and listed its location as unknown. It also said Binance Holdings Limited operated the online crypto-trading service Binance. The agency cautioned that those identifying details came from information available online and might not reflect the company’s current particulars.

The development mattered because it put a direct regulatory objection against one of the cryptocurrency market’s most prominent international trading platforms. It also illustrated a central institutional conflict of the period: an exchange could make services accessible across borders, while regulators continued to apply licensing and customer-protection requirements country by country.

A warning, not a license revocation

The precise character of the action is important. The FSA described it as a warning issued under section III-1-6(2)(ii) of its administrative guidelines for crypto-asset exchange providers. The document did not announce a criminal judgment, a monetary penalty, a loss of customer funds or the revocation of a Japanese license. Binance did not have the registration that the agency said was required for the activity at issue.

The surviving notice also did not quantify the number of Japanese residents involved, their assets, Binance’s Japan-related trading volume or any resulting market-price movement. It therefore supports a firm conclusion about the regulator’s position, but not a calculation of the warning’s immediate financial effect.

A contemporaneous report from CoinDesk described the FSA’s action on June 25, 2021, as another warning that Binance was operating without registration. That description is consistent with the regulator’s own historical record.

Japan had warned Binance before

The June 25 action was not the first time Japan’s regulator had raised this issue with Binance. An FSA publication covering March 2018 stated that crypto-exchange business could not be conducted without registration from the FSA or a local finance bureau. It listed Binance among two businesses sent warnings, with Binance’s earlier warning dated March 23, 2018.

That history made the 2021 notice more significant than an initial request for clarification. Three years after the earlier warning, the agency was again publicly asserting that Binance was dealing with Japanese residents without the required registration. The record available on June 25 did not explain what operational changes, if any, the FSA expected Binance or Japanese users to make in response.

Why the jurisdictional boundary mattered

The warning highlighted how regulatory status attached to legal entities and activities rather than to a globally recognized brand name alone. Internet access to a platform did not establish that the operator held permission to provide every service in the user’s jurisdiction.

For the industry, that distinction affected market access, compliance costs and the durability of global product distribution. For customers, it created a separate question from whether a platform was technically reachable: whether a domestic regulator had registered the provider and could supervise its local activity. The June 25 notice did not evaluate Binance’s solvency, custody arrangements or trading technology, so it should not be read as a broader finding on those subjects.

Later context

A separate UK Financial Conduct Authority restriction was imposed on Binance Markets Limited on June 25, 2021, but the FCA’s consumer warning was first published on June 26. The FCA later released its detailed supervisory notice on August 25. That subsequent record reinforced the broader pattern of jurisdiction-specific scrutiny, but it was not public evidence available when Japan’s June 25 warning appeared and does not alter the narrower Japanese finding reconstructed here.
