Japan Emerges as Key Hub for Russian Intelligence Amid Ukraine War

Since Russia's full-scale invasion of Ukraine in February 2022, Western countries have expelled hundreds of Russian spies and imposed sanctions to disrupt Moscow's intelligence and weapons supply chains. However, a New York Times investigation reveals that many expelled Russian operatives have shifted their focus to Japan, which has become a crucial intelligence and technology hub for Russia. Japan's traditionally weak espionage laws and advanced high-tech industry have made it a prime target for Russian intelligence efforts.

Central to this operation is the secretive Russian military intelligence unit known as "Directorate 20," which operates under diplomatic or business covers in Tokyo. The unit is led by Maxim Vladimirovich Pilchenkov, a veteran GRU officer who arrived in Tokyo in February 2024 posing as an employee of the Russian state airline Aeroflot. Pilchenkov has established connections with logistics companies facilitating the transfer of sensitive dual-use technologies from Japan to Russia, often through third countries like Vietnam.

According to Ukrainian government estimates, about 90% of Russian missiles and drones contain Japanese-made components, despite export bans. For example, parts from Japanese companies such as NEC, Panasonic, and Toshiba were found in Russian weapons used in attacks on Ukrainian civilians, including a Kh-101 cruise missile strike in Kyiv in May 2025 that killed at least 24 people. Ukraine has sent multiple diplomatic notes to Japan presenting evidence of Japanese technology in Russian arms, but Tokyo's response has been slow.

Japan's intelligence capabilities remain limited due to post-World War II restrictions, lacking a foreign intelligence agency and having weak espionage laws. This has allowed Russian spies to operate with relative impunity near Tokyo's National Police Agency headquarters. In response, Prime Minister Sanae Takaichi's government is now working to strengthen Japan's intelligence and export controls to prevent illegal technology transfers and counter espionage activities. In January 2025, Tokyo police uncovered a Russian spy posing as a Ukrainian attempting to steal trade secrets, highlighting ongoing security challenges.

This shift in Russia's intelligence focus to Japan is critical for sustaining its war effort in Ukraine, enabling continued access to advanced technologies despite Western sanctions and crackdowns.
