Japan has added Garantex, the Russian cryptocurrency exchange already under U.S. and EU sanctions, to its asset freeze list. The designation came on Oct. 2 as part of a broader Russia package covering 33 entities, nine individuals and restrictions on 35 vessels.

For a platform that has been sanctioned, raided, indicted and, according to U.S. authorities, effectively reconstituted under a new name, one more designation may look symbolic. It is more interesting than that. Japan’s action shows both the reach and the limits of sanctions built around legal names in a market where the economic activity can move faster than the lists.

What Japan actually did

Japan’s Ministry of Foreign Affairs introduced the measures under the Foreign Exchange and Foreign Trade Act, following a Cabinet decision on sanctions connected to Russia and the war in Ukraine.

The mechanism is a permission system. Payments to the 33 listed entities and nine listed individuals now require government permission. The same requirement applies to capital transactions involving deposits, trusts and money loans with designated parties.

The ministry’s appendix identifies the target as Garantex Europe OU, with Garantex listed as an alias, and gives addresses in St. Petersburg and Moscow, including Federation East Tower in Moscow City. Garantex is the only cryptocurrency exchange named among the latest Russian entities.

The package goes beyond finance. Japan prohibited exports to four specific entities located outside Russia and Belarus and announced further restrictions on goods that could contribute to Russia’s industrial capabilities. For the 35 vessels, providing services specified by Japan’s Ministry of Finance now requires permission, and money loans and debt guarantees tied to the sale, purchase, lease or charter of those vessels face similar controls.

An asset freeze with no assets identified

Japan describes the measures as an asset freeze. The notice, however, does not disclose the value of any Garantex assets located in Japan. It does not identify cryptocurrency wallets connected to Garantex, and it does not state that any particular amount of digital assets was frozen.

That gap is worth dwelling on. In traditional finance, a name based designation works because names map onto accounts. A bank screens its customer files, finds the listed party, and blocks the account. With a crypto exchange, the relationship that matters is often not a customer account at all but a transfer to or from a wallet address. A designation that lists a legal entity and its alias, without addresses, leaves the work of connecting that name to onchain activity to the firms doing the screening.

This is analysis rather than anything the Japanese government has said. But the practical consequence is clear enough: the effectiveness of this listing in the crypto context will depend largely on how compliance teams translate a corporate name into the addresses and counterparties they actually see.

The long paper trail behind the designation

Japan is arriving late to a well documented case.

The U.S. Treasury’s Office of Foreign Assets Control first sanctioned Garantex in April 2022. Treasury said its analysis linked more than $100 million in known Garantex transactions to illicit actors and darknet markets, including funds associated with the Conti ransomware group and the Hydra marketplace.

The European Union followed in February 2025, listing Garantex in its 16th sanctions package against Russia. The Council of the EU described the exchange as closely tied to Russian banks already under EU sanctions. The listing imposed an EU asset freeze and barred EU citizens and companies from making funds available to it.

Weeks later, enforcement moved from paper to infrastructure. On March 6, 2025, U.S. authorities seized three domains used by the exchange, while German and Finnish authorities seized servers supporting its operations. Garantex suspended its services after Tether froze more than 2.5 billion rubles worth of USDT connected to the exchange.

The Justice Department then unsealed charges against Garantex administrators Aleksej Besciokov and Aleksandr Mira Serda. Prosecutors alleged that the exchange facilitated money laundering and sanctions violations and said it had processed at least $96 billion in cryptocurrency transactions since April 2019. Those criminal accusations remain allegations and have not been proven in court.

In August 2025, OFAC designated Garantex again, this time under U.S. cyber sanctions authorities, stating that the exchange had “directly facilitated” ransomware actors and other cybercriminals.

The successor problem

The most important part of this story may be the part Japan’s list does not reach.

After the March 2025 disruption, U.S. authorities said Garantex moved customers and funds to another exchange, Grinex. Treasury’s August 2025 notice described Grinex as a successor created by Garantex employees to keep providing services after the law enforcement action. OFAC said customer deposits were transferred to the new platform and that Grinex went on to process billions of dollars in cryptocurrency transactions.

Treasury also said Garantex customers regained access to some balances through A7A5, a digital asset backed by the ruble and issued by Old Vector. According to Treasury, A7A5 was created for customers of A7, a Russian cross border settlement company that U.S. authorities accused of supporting sanctions evasion.

Since Garantex is the only cryptocurrency exchange named among the new Russian entities, Japan’s latest package does not list Grinex. Here lies the structural weakness of entity based sanctions in this sector. A designation attaches to a legal person and its known aliases. If the operation that matters has already migrated to a new name, a new platform and a new settlement token, a list that names the old entity captures its history more than its present activity.

None of this makes the Japanese listing pointless. It closes a jurisdiction, aligns Japan with its partners, and puts any residual Garantex exposure in Japan under a permission regime. But readers should be precise about what it targets.

One day earlier in Washington

The timing is notable. On Oct. 1, 2026, one day before Japan’s announcement, Treasury sanctioned the A7 Network as a transnational criminal organization, and the Financial Crimes Enforcement Network proposed restrictions on fund transfers involving its sub agents. FinCEN said its investigation found that A7 sub agents processed more than $17 billion between January 2025 and June 2026.

Two cautions follow. First, nothing in the record establishes that the U.S. and Japanese actions were coordinated, so the sequence should not be read as proof of a joint operation. Second, the figures must not be blended. The $17 billion concerns A7 sub agents, not Garantex. Treasury’s Garantex findings put known transactions linked to illicit actors at more than $100 million, while the Justice Department’s $96 billion figure refers to the exchange’s total cryptocurrency volume since 2019. These are three different numbers measuring three different things.

The November deadline

Japan’s payment and capital controls on the 33 entities and nine individuals took effect with the Oct. 2 measures. The English language notice announced no separate grace period for transactions involving Garantex.

The vessel restrictions carry a narrower transitional rule. They apply to obligations and services performed on or after Oct. 2, but obligations or services based on contracts concluded before that date may proceed only if they are carried out before Nov. 1, 2026. Anyone with legacy exposure on those vessels is working against a fixed and short clock.

The takeaway for bitcoiners

The Garantex saga illustrates where state power in this market actually lands. Governments do not sanction a protocol. They sanction intermediaries: custodial exchanges, issuers, settlement companies and the businesses that connect them to the banking system. That is where names, addresses in the corporate sense, servers and domains exist, and that is where enforcement has repeatedly bitten.

Japan’s designation adds one more jurisdiction to that perimeter. Whether it adds real pressure depends on what follows: whether successor platforms are named, and whether compliance teams can turn a corporate name into the onchain activity it actually represents.
