Available Evidence Does Not Verify a Japanese Freeze of Garantex
A claim that Japan froze Garantex and sanctioned 33 Russian entities is not supported by the Japan-related report available here. That report describes other categories of sanctions and does not mention the cryptocurrency exchange.
- Garantex in Japan’s measures? Not mentioned in the cited report.
- Thirty-three Russian entities? Not established by the reported figures.
- Separate Garantex action: U.S. authorities reported a 2025 operation in which more than $26 million in cryptocurrency was frozen.
The distinction matters. Sanctioning people or companies, restricting an exchange’s assets and shutting down its operations are different measures. Conflating them can turn a specific claim about government action into something broader and potentially misleading.
What the Japan-related report says
Ukrainska Pravda, citing Radio Liberty and a Japanese Ministry of Finance document, reported Japanese sanctions involving nine Russian citizens, 35 vessels, and companies from Türkiye and the United Arab Emirates. The report does not mention Garantex.
Those figures do not, on their own, disprove a separate count of 33 entities. People, vessels and companies are different categories, and the lists may cover different groups. But the cited report neither supports that total nor explains what the number 33 counts. The Japanese Ministry of Finance notice is needed to confirm the exact list, legal basis and scope of the measures.
The careful conclusion is that the claim Japan froze Garantex remains unverified, not that the available figures definitively prove it false. The report also does not clarify what “freeze” would mean in this case. It could refer to restrictions on particular assets, services or operations.
Garantex’s documented U.S. enforcement history
Garantex has faced sanctions and law-enforcement action, but the documented measures described by the U.S. Treasury involve U.S. authorities and their partners, not Japan.
The Treasury Department’s Office of Foreign Assets Control (OFAC) designated Garantex on April 5, 2022, under Executive Order 14024. Treasury said the cryptocurrency exchange operated in Russia’s financial services sector. It also says Estonia’s Financial Intelligence Unit withdrew Garantex’s digital-asset services licence in February 2022, citing anti-money-laundering and counter-terrorist-financing deficiencies.
On March 6, 2025, the U.S. Secret Service worked with German and Finnish law enforcement on measures targeting Garantex’s computer infrastructure. Treasury reported that authorities seized the exchange’s web domain and froze more than $26 million in cryptocurrency controlled by Garantex. Its public account describes the freeze as part of the operation but does not, in the material cited here, identify who technically carried it out.
On March 7, 2025, the U.S. Department of Justice unsealed indictments against Garantex executives Aleksandr Mira Serda and Aleksej Besciokov. Treasury says Besciokov was arrested in India. These were separate U.S. enforcement actions and do not verify a Japanese measure.
On August 14, 2025, OFAC announced further designations involving Garantex, its successor Grinex, three Garantex executives and six associated companies in Russia and the Kyrgyz Republic. Treasury said Garantex moved customer funds and operations to Grinex after the March disruption. It also reported that more than $100 million in known Garantex transactions were associated with illicit actors, including ransomware groups and darknet markets. These characterizations and figures come from Treasury.
What does a crypto asset freeze mean?
An asset freeze generally restricts dealings with specified property or interests in property under the authority of the government imposing the measure. Its practical reach depends on the law, the assets involved and who controls them.
A freeze does not automatically mean an exchange has been shut down worldwide or that every customer’s funds have been seized. Nor can a government switch off Bitcoin’s decentralized protocol. Still, bitcoin held through an exchange is not untouchable. A custodian may restrict access to assets it controls, and sanctions can make identified addresses difficult or risky for regulated services to handle. Centralized token issuers may also be able to restrict tokens under their control.
Garantex is a cryptocurrency exchange, not the Bitcoin network. The useful questions are specific: Which authority acted? What property or services were targeted? Whose access was affected? The phrase “Japan froze Garantex” answers none of them, and the cited Japan-related report does not support the claim.
Key questions and answers
-
Did Japan freeze Garantex?
The cited Japan-related report does not mention Garantex. The claim remains unverified unless the Japanese Ministry of Finance notice confirms it.
-
Did Japan sanction 33 Russian entities?
The cited report does not establish that total. It lists different categories, which should not be treated as a direct contradiction without comparing the underlying lists.
-
Was Garantex-related cryptocurrency frozen?
Yes. The U.S. Treasury reported that more than $26 million in cryptocurrency controlled by Garantex was frozen during a March 2025 operation involving U.S., German and Finnish authorities.
-
Can a government freeze Bitcoin itself?
No government can switch off the Bitcoin protocol. Authorities can, however, restrict access to bitcoin held by a custodian or target services and entities associated with identified addresses.
