How Russia Reportedly Used Japan To Source Electronics for Ukraine War

When Russian troops crossed into Ukraine in February 2022, Western governments expelled hundreds of suspected Russian intelligence officers and imposed sweeping sanctions aimed at cutting Moscow off from advanced technology needed for weapons production. However, according to a report by The New York Times, many of those operatives regrouped in Japan, where they allegedly built a network to acquire sensitive electronics despite export restrictions.

The report says Japan's advanced technology industry, combined with comparatively weak espionage laws, has made it an important source of components for Russia's military. Ukrainian government estimates cited by the NYT suggest that around 90 per cent of Russian missiles and drones contain parts made in Japan. India Summons Russian Diplomat After Cargo Ship Missile Attack Kills 4 Indian Sailors (Video).

Russia's Alleged Intelligence Operation

At the centre of this network, according to the NYT, is a little-known Russian military intelligence unit known as the 20th Directorate. Its officers reportedly pose as diplomats or businesspeople while working to acquire or steal battlefield technology before smuggling it back to Russia.

This account is based on information provided by current and former officials from five Western intelligence agencies who spoke to the newspaper. Russian Strikes Kill 4 in Ukraine as Volodymyr Zelensky Faces Political Crisis After Defence Minister's Ouster.

The man identified by the NYT as leading the Tokyo operation is Maksim Vladimirovich Filchenkov, who reportedly operates under the cover of a position at Russian state airline Aeroflot. Officials from four intelligence agencies told the newspaper that he plays a significant role in helping Russia obtain military technology.

Missile Debris and Japanese Components

The NYT highlights what it describes as the human cost of the alleged supply chain. The report notes that in May, a Russian Kh-101 cruise missile struck a residential building in Kyiv, killing at least 24 people. Investigators who examined the missile wreckage reportedly found Japanese-made components inside its guidance system despite those parts being subject to export restrictions to Russia.

How the Network Reportedly Operates

According to the NYT, Filchenkov, 49, arrived in Tokyo in February 2024 as Russia increasingly sought advanced technology while shifting its military strategy toward drone warfare.

Although China continued supplying some technology, the newspaper says specialised machine tools and electronics from advanced economies remained difficult for Moscow to replace.

A veteran officer with Russia's military intelligence agency, the GRU, Filchenkov had previously served in Japan and reportedly developed relationships with logistics companies involved in shipping goods between Japan and Russia.

Western officials cited by the NYT have warned Japanese authorities that these connections allow GRU officers to obtain sensitive technology using false identities and falsified shipping documents.

Aeroflot itself is not formally sanctioned in Japan, the report says, although the airline has effectively ceased operations there because it cannot obtain the parts and services needed to maintain flights. Some of its business partners, however, reportedly continue operating.

The NYT also reports that rather than sending restricted goods directly to Russia, smugglers allegedly move them through intermediary countries. Vietnam is identified as the largest recipient of Japan's sensitive technology and, in turn, the largest exporter of such technology to Russia.

Ukraine's Repeated Warnings

According to the NYT, Ukraine has repeatedly raised the issue with Japan's Foreign Ministry.

In April 2025 alone, Kyiv reportedly sent at least eight diplomatic letters detailing evidence of Japanese-made components recovered from Russian weapons used in attacks on civilians. Around eight additional communications reportedly followed during the year, including photographs and inventories of recovered circuit boards, semiconductors and transmitters.

The documentation reportedly named Japanese companies including Nippon Electric Corporation, Panasonic and Toshiba.

The NYT notes there is no evidence that any of these companies knowingly supplied Russia.

The companies denied wrongdoing and said they comply with Japan's export regulations. Nippon told the newspaper that the components identified by Ukraine were old products that had not been sold for several years.

Japan's Ministry of Economy, Trade and Industry said it has issued repeated warnings to businesses about sanctions evasion and has blacklisted dozens of overseas entities suspected of helping Russia bypass export controls.

Japan Strengthens Counter-Espionage Efforts

The report says Japan has long been viewed as relatively vulnerable to foreign intelligence operations because of post-war limits placed on its intelligence services and the absence of a dedicated foreign intelligence agency.

Japanese officials told the NYT they recognise the growing threat and are working to expand intelligence capabilities and strengthen enforcement against illegal technology exports.

Despite the allegations outlined in the report, Japan has remained one of Ukraine's strongest supporters in Asia. Tokyo joined US and European sanctions immediately after Russia's invasion and later supplied military equipment, including bulletproof vests and helmets, marking a significant shift from its long-standing post-war defence policy.

Under Prime Minister Sanae Takaichi, Japan has also launched initiatives aimed at improving intelligence capabilities to counter espionage and prevent the illicit export of sensitive technology.
