Japan's new intelligence bureau raises oversight concerns, signals strategic shift

Japan's newly established National Intelligence Bureau, which began operations on July 31, has drawn criticism for its lack of independent oversight, with experts warning it marks a significant departure from the country's post-war pacifist principles.

Michel Ruimy, a professor of economics at Sciences Po and specialist in international relations, said the bureau centralizes intelligence functions under the direct authority of the prime minister. The agency was created following a law enacted in May that also set up the National Intelligence Council, a command body chaired by the prime minister and comprising nine other Cabinet ministers.

The bureau acts as the council's secretariat, coordinating intelligence from the National Police Agency, the Foreign Ministry, the Defense Ministry, and other government bodies. It holds the authority to compel these organizations to share information.

Ruimy noted that the centralized structure shortens the chain of command, allowing decision-making time in a crisis to be reduced from hours of discussion to mere minutes. He pointed out that human, technical, and cyber intelligence are now synchronized under this new framework.

The reform, however, extends beyond administrative restructuring. Ruimy highlighted that the Takaichi administration has already initiated the largest rearmament program since 1945, with defense spending projected to reach two percent of GDP by 2027. The government has also lifted restrictions on arms re-exports and strengthened security cooperation with the United States, Australia, and Germany.

"Japan is thus demonstrating its desire to break free from the post-war pacifist framework," Ruimy said. He added that this shift is reshaping the balance of power in the Indo-Pacific, forcing all regional actors, particularly China, to recalibrate their strategies.

Analysts view the intelligence reform as part of a broader move from a defensive to a more assertive security posture under Prime Minister Sanae Takaichi, raising questions about the adequacy of checks and balances in Japan's evolving security architecture.
