Japan's Garantex freeze lands 19 months after police seized the exchange's servers
Japan froze the assets of Garantex, a Moscow crypto exchange that processed at least $96 billion, in Russia sanctions that took effect on October 2. Any exchange or payment firm that touches Garantex now carries Japanese legal risk on top of its US and EU exposure.

What happened
- Most of the package targeted Russia's war economy, including defense makers Tulamashzavod and Motovilikhinskiye Zavody and individuals tied to defense conglomerates.
- Japan brought no fresh accusations against Garantex and extended restrictions already in place against the exchange.
- A March 2025 international law enforcement operation seized Garantex's domains and servers in Germany and Finland.
- In August 2025 US authorities sanctioned Grinex, an exchange they deemed Garantex's successor, along with three Garantex executives.

Why it matters
- cost Compliance teams at Japan-exposed exchanges and payment firms pay in screening work, adding Japan's list to the wallet and counterparty checks they already run.
- constraint The freeze adds little pressure on Garantex itself, because the 2025 seizures had already disrupted the business and Crypto Briefing found no trading data to measure a fresh effect.
- precedent Whether Tokyo extends its list to successor entities will test if coordinated sanctions can keep up with platforms that rebrand faster than lists are updated, according to Crypto Briefing.
By Crypto Briefing's count, Garantex processed at least $96 billion from April 2019 [8]. The more than $26 million frozen in the March 2025 seizure [12] comes to about 0.027 percent of that, or roughly $27 for every $100,000 that passed through the exchange [1]. Japan's order arrives 19 months after that seizure [2]. It also comes about four years after the US Treasury's Office of Foreign Assets Control sanctioned the exchange in 2022 [10][3], a year that began with Garantex losing its Estonian licence over anti-money-laundering deficiencies [9].
Crypto took up a small part of Tokyo's package. Garantex is one of 42 names on the freeze list, 33 entities and nine individuals [4], in a round that also restricted services and financing for 35 shadow-fleet vessels [4]. Washington and Brussels had already targeted the exchange over alleged sanctions evasion and illicit finance [7], so Tokyo could reuse a record others built.
The freeze can play out in a few ways. If Japanese exchanges or payment firms find leftover Garantex-linked wallets, the screening catches real money and the order matters more than its timing suggests. If they find nothing, the listing is a legal backstop for a platform that law enforcement had already disrupted in 2025. Russia-linked crypto routes narrow only if Tokyo follows Washington onto Grinex [13]. The US took that step 14 months before Japan got to Garantex [5].
I think the second outcome is the likeliest. Japan listed Garantex roughly four years after OFAC did [3], and a quick Japanese move on Grinex would break that pattern. The view is wrong if Japanese authorities report frozen Garantex-linked balances of any size, or if Tokyo's next Russia round names Grinex.
What to watch
- A Japanese sanctions round that adds Grinex or the three Garantex executives Washington sanctioned in August 2025.
- Any report from Japanese authorities or Japan-based firms of frozen Garantex-linked balances beyond the $26 million seized in 2025.
- Whether the EU extends its own Garantex sanctions to successor platforms.
