Japan has acknowledged the need to better counter foreign espionage after a New York Times investigation reported that Russia had turned the country into a 'den of spies' and a key source of weapons components.
Key facts
- A government spokesman said the issue must be addressed with 'even greater rigour'.
- A New York Times investigation published Sunday described Japan as a Russian 'den of spies'.
- The report cited Japan's 'weak espionage laws' as enabling intelligence gathering.
- Russia allegedly used Japan to procure dual-use technology for its war in Ukraine.
Japan has said it recognises the need to counter foreign intelligence more effectively, following a New York Times report that Russia had turned the country into a ‘den of spies’ and a key source of weapons components, according to the Guardian.
A government spokesman said the issue must be addressed with ‘even greater rigour,’ responding to the investigation into how Japan has reportedly become a spy hub for Russian President Vladimir Putin.
The New York Times, in an investigation published on Sunday, reported that thanks to ‘weak espionage laws,’ Moscow was using Japan as a key hub for intelligence gathering and the procurement of dual-use technology.
According to the report, that dual-use technology is needed for Russia’s ongoing war in Ukraine. Dual-use goods are items that can serve both civilian and military purposes, making them a focus of export controls in many countries.
The acknowledgement from Tokyo signals official recognition of the concerns raised by the investigation, though the government’s statement centred on the broad need to strengthen counter-espionage efforts rather than specific new measures.
Why it matters
Espionage and the flow of sensitive technology have become central concerns as governments seek to limit support for Russia's war in Ukraine. Japan's response highlights how allied nations are being pressed to tighten intelligence and export controls to prevent their territory being used for hostile procurement.
