The Japanese government has expanded its sanctions against Russia, citing the continuing war in Ukraine. These measures now include the Russian cryptocurrency exchange Garantex under an asset freeze list that restricts payments and capital transactions with targeted parties, according to a joint statement issued on Friday by Japan’s Ministry of Foreign Affairs, Ministry of Finance, and Ministry of Economy, Trade and Industry. The new sanctions also target 33 other organizations and nine individuals linked to Russia, alongside 35 vessels identified as part of the so-called “shadow fleet” carrying Russian oil. Specifically, the measures restrict services such as repairs and insurance for these designated vessels.
Garantex was previously sanctioned by the US, the EU, and other jurisdictions for helping Russian entities evade financial restrictions. Through these actions, Japan aims to reduce Russia’s earnings from crude oil exports. However, blockchain intelligence firm TRM Labs reported in August 2025 that Garantex may have already possessed contingency plans to skirt the impact of US actions. The US Treasury’s Office of Foreign Assets Control had sanctioned Garantex a second time, along with its successor, Grinex. TRM Labs noted that such sanctions may be ineffective because entities like Garantex appear to prepare contingency plans well in advance, allowing them to quickly migrate clients, infrastructure, and funds to successor platforms.
Japan’s inclusion of Garantex on its asset-freeze list signals a coordinated effort among major economies to close regulatory gaps exploited by sanctioned entities. By restricting payments and capital transactions, Tokyo aligns its enforcement posture with Washington and Brussels, aiming to disrupt the financial lifelines supporting Russia’s war economy. This move underscores the growing recognition that cryptocurrency exchanges serve as critical nodes in evasion networks, necessitating direct intervention beyond traditional banking channels.
However, the effectiveness of these sanctions remains questionable given historical precedents of rapid platform migration. As noted by TRM Labs, entities like Garantex often maintain pre-existing contingency plans that allow them to shift operations to successor platforms such as Grinex before or immediately after enforcement actions. This dynamic suggests that static lists may struggle to contain sophisticated evasion tactics, highlighting the need for continuous monitoring of infrastructure changes rather than relying solely on entity designation.
