Japan is making unprecedented progress in the modernization of its security and intelligence structure, with the largest reform since the end of World War II.
This shift comes amid concerns about its vulnerability to foreign operations, especially following allegations that point to the country as a key location for espionage and the provision of sensitive technology.
The most recent trigger was an investigation published by The New York Times, which described Japan as a “spy haven” used by Russia for both intelligence gathering and the acquisition of dual-use components intended for its war in Ukraine. According to that report, the country’s “weak espionage laws” facilitated the establishment of these networks.

Russian Espionage in Japan
The concern is not new, but it has escalated over time. Considered for decades as a permissive environment for foreign intelligence agencies, Japan has experienced increased espionage activity following the Russian invasion of Ukraine, when numerous agents were expelled from Western countries and relocated to Japanese territory.
In this context, Nikkei Business reported in August 2022 that around 120 Russian intelligence agents were operating in the country, a figure that reflects the magnitude of the phenomenon.
The problem also manifests in the corporate sphere. In January, Tokyo's public security office reported that an employee of a Japanese machine tool company had leaked trade secrets to an alleged agent of Russia's Foreign Intelligence Service.
The case highlighted the limitations of the current legal framework, as it was treated as unfair competition rather than under specific legislation against espionage.
