Japan’s New Intelligence Agency: Why Tokyo is Building Its Own Spy Network (2026)

Japan's decision to establish its first centralized intelligence agency since World War II is a significant move that reflects a shift in the country's security strategy. This development comes amidst a changing geopolitical landscape, with Japan aiming to modernize its defense capabilities and address the evolving threats it faces.

The new agency, the National Intelligence Council, will serve as the government's command center for intelligence gathering and analysis, while the National Intelligence Bureau will handle operational tasks. This reform marks a departure from Japan's decades-long reliance on US intelligence support and its pacifist stance enshrined in the post-war constitution.

A Shift in Security Posture

Prime Minister Sanae Takaichi's government views this legislation as a "first step" towards strengthening Japan's espionage capabilities. The agency's creation is a response to the increasing challenges posed by neighboring countries, including North Korea, Russia, and China. Japan's foreign and national security policies have traditionally followed the US, but the Trump administration's emphasis on American alliances and defense spending has prompted Japan to pursue its own intelligence capabilities.

The absence of an anti-espionage law in Japan has made it relatively easy for foreign intelligence activities to go unnoticed and unpunished. This has made Japan an attractive target for foreign adversaries, as noted by former Russian intelligence officers who operated in the country. The establishment of the new agency aims to address this vulnerability by providing the legal framework needed to conduct undercover operations and investigations.

Addressing Internal Challenges

Japan's current intelligence structure faces significant challenges due to its decentralized nature. The Cabinet Intelligence and Research Office (CIRO) has lacked the authority to enforce cooperation among agencies and prevent the scattering of intelligence data. This has hindered the effectiveness of Japan's intelligence efforts.

The new agency aims to strengthen coordination, reduce inter-agency barriers, and ensure that intelligence products better meet policymakers' requirements. By centralizing intelligence operations, Japan hopes to improve its ability to gather and analyze information, making it more responsive to the evolving security landscape.

Surveillance and Public Perception

Japan's history with surveillance and state monitoring is a complex one. The country's defeat in World War II and the subsequent drafting of Article 9 in the constitution led to a deep-rooted distrust of state surveillance among its citizens. The wartime Special Higher Police, known as the Tokko, monitored, arrested, and tortured citizens for their political beliefs, leaving a lasting impact on the country's psyche.

However, the latest reforms do not amount to a return to the espionage apparatus that could be used against Japanese civilians, according to Sanshiro Hosaka, a research fellow at the International Centre for Defence and Security. The legislation focuses on improving coordination and transparency rather than expanding surveillance powers.

The Way Forward

As Japan continues to navigate the complexities of modern security challenges, the establishment of the National Intelligence Council represents a significant step towards a more robust and independent intelligence apparatus. The country's evolving security strategy, influenced by the geopolitical dynamics of the region, will shape its future intelligence capabilities and its role in the global security landscape.
