Japan has emerged at the center of the military technology smuggling network fueling Russia's war in Ukraine. A comprehensive New York Times investigation documented that, despite Western sanctions imposed after the 2022 invasion, Moscow has been obtaining advanced technology components through Japan via a complex structure operating under diplomatic and commercial covers.
Secret Russian Unit in Tokyo
According to the report, which is based on Western intelligence officials, at the heart of the operations is a previously undisclosed secret unit called the '20th Directorate,' affiliated with Russian military intelligence. This unit is tasked with purchasing or stealing sensitive technologies and smuggling them to Russia through companies and intermediaries.
The unit reportedly operates from the office of Russian airline Aeroflot in Tokyo, with Russian officer Maksim Vladimirovich Vilchenkov, posing as a company employee, directing the operations.
Japanese Components in Russian Missile Systems
According to estimates by the Ukrainian government, approximately 90 percent of Russian missiles and drones contain Japanese-origin components. This shows how vital Japanese technology is for the Russian military-industrial complex at a time when Western sanctions are tightening.
The NYT investigation reports that Japanese electronic parts, whose export to Russia is banned, were found in the wreckage of a Russian KH-101 cruise missile that struck a residential building in Kyiv last May.
Method to Circumvent Sanctions: Intermediary Countries
Instead of direct shipments from Japan, Russia first sends the products to intermediary countries such as Sri Lanka, Uzbekistan, and Vietnam, and then transports them to Russia. This method is used to try to bypass export controls.
The investigation highlights a Japanese company called Proco Air, described as a 'bridge between Japan and Russia.' The company's owner, Takehiko Miki, acknowledges doing business with Vilchenkov for years but claims he was unaware of his connection to Russian intelligence and that he did not transport prohibited goods.
However, shipping documents examined by journalists reveal Proco Air's commercial relationship with the Russian company R-Farm, which is not on the sanctions list. R-Farm's founder, Aleksey Ribik, is on the sanctions lists of the UK, Canada, and Australia due to his close ties with Russian President Vladimir Putin and his support for the war effort.
Japan's Weak Response and Intelligence Gap
Throughout 2025, Ukraine sent a series of diplomatic notes to Japan's Foreign Ministry, providing photographs and lists of Japanese parts found in Russian weapons. The lists included products from major Japanese companies such as Panasonic, Toshiba, and NEC. The companies stated that they fully comply with sanctions and do not sell their products to Russia, and that the parts reached Russia through re-exports via third countries.
Western and Ukrainian officials express frustration that, despite repeated warnings from allies, Japanese authorities have not brought any charges against the companies or the Russian officer and have been slow to prevent sanctions violations.
According to the NYT, one reason for the problem is Japan's weak counter-espionage system. The country, which lacks an independent foreign intelligence agency, has less strict espionage laws compared to other Western nations. This makes Japan a favorable environment for Russian intelligence operations.
The investigation concludes that Russia's ability to sustain its war in Ukraine depends not only on its military resources but also on its success in maintaining covert channels to access Western technology. This makes Japan, which provides political support to Kyiv, one of the most important arenas in the intelligence war behind the front lines.
