A comprehensive investigation by The New York Times (NYT) reveals that Russia has turned Japan into a key hub for accessing advanced technology despite sanctions imposed after its 2022 invasion of Ukraine. According to the investigation, Moscow is procuring critical electronic components, microchips, and equipment for its military industry through Japan, exploiting complex smuggling networks operating under diplomatic and commercial covers and legal loopholes.
Secret Unit in Tokyo: The 20th Directorate
The report, based on Western intelligence officials, states that at the center of operations is a previously undisclosed secret unit called the "20th Directorate," attached to Russian military intelligence. This unit is tasked with purchasing or stealing sensitive technologies and smuggling them to Russia through companies and intermediaries.
The unit operates from the office of Russian airline Aeroflot in Tokyo, and Russian officer Maksim Vladimirovich Vilchenkov, who appears to be a company employee, is said to be running the operations.
Japanese Signature on Russian Missiles
According to estimates by the Ukrainian government, approximately 90 percent of Russian missiles and drones contain Japanese-origin components. This highlights how vital Japanese technology is for the Russian military-industrial complex at a time when Western sanctions are tightening.
The NYT investigation reports that the wreckage of a Russian KH-101 cruise missile that struck a residential building in Kyiv last May contained Japanese electronic parts whose export to Russia is banned.
Network of Intermediary Countries and Companies
Instead of direct shipments from Japan, Russia first sends the products to intermediary countries such as Sri Lanka, Uzbekistan, and Vietnam, and then forwards them to Russia. This method is used to circumvent 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 Slow Response and Weak Intelligence Structure
Throughout 2025, Ukraine sent a series of diplomatic notes to the Japanese 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 in question 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 countries. 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.
