On April 23, Japan’s House of Representatives passed a bill to establish the National Intelligence Council, in what would be the most significant reform of the country’s intelligence architecture in the postwar era. The bill now moves to the House of Councillors, where the opposition holds a stronger position. But the lower house passage, without amendment, already revealed something important about how the framing of this debate shaped its outcome.

The legislation seeks to upgrade the Cabinet Intelligence and Research Office (CIRO) into a National Intelligence Agency and establish a National Intelligence Council chaired by the prime minister. Every party except the Japanese Communist Party voted in favor – including the opposition Centrist Reform Alliance, whose chief negotiator, Goto Yuichi, led 21-and-a-half hours of committee deliberation as the panel’s senior opposition leader. 

Yet the breadth of that majority conceals a genuine tension. Serious structural concerns were raised during deliberations, partially addressed through political commitments, and then left without institutional safeguards in the final version of the bill.

This raises a question worth examining through the lens of securitization theory: Did the framing of this reform as a security imperative foreclose the kind of legislative scrutiny that could have produced better institutional design?

The Case for Reform

The case for intelligence reform is clear. Japan’s intelligence community has long suffered from structural fragmentation. Information has been siloed across agencies – the National Police Agency, the Ministry of Defense’s intelligence apparatus, the Ministry of Foreign Affairs’ Intelligence and Analysis Service, and the Public Security Intelligence Agency – with limited mechanisms for consolidation. The CIRO, despite its coordinating mandate, lacked statutory authority to compel information sharing. 

Allies – particularly the United States – have pressed Japan to improve its capacity for intelligence consolidation, a prerequisite for deeper integration into regional security frameworks. The ruling coalition’s ambition to eventually create a dedicated foreign intelligence service reflects a serious institutional project.

Intelligence reform was needed in Japan. But it’s worth scrutinizing whether the solution offered by this bill was the best available option.

How the Debate Was Securitized

In the framework made famous by Barry Buzan and Ole Wæver, securitization is the move by which an issue is lifted out of normal political deliberation and framed as an existential threat requiring extraordinary measures. The scholars’ normative argument is that this move should be resisted wherever possible, because it suspends the democratic contestation through which better policy is produced.

Prime Minister Takaichi Sanae framed the bill in explicitly existential terms, declaring that “foreign influence operations, including the spread of disinformation, constitute a threat that can shake national security.” A Jiji Press poll found 39.1 percent of Japanese were in favor, 19.0 percent opposed, and 41.9 percent unable to decide. The bill passed in the space created by suspended judgment rather than active conviction.

The objections raised during deliberation were exactly the kind of design issues that normal legislative processes are meant to resolve. Haruna Mikio, one of Japan’s foremost intelligence researchers, argued that the domination of the new agency by the National Police Agency – a law enforcement body, not an analytical one – would undermine its stated purpose. 

Veteran diplomat Yachi Shotaro, the first head of the National Security Secretariat under Prime Minister Abe Shinzo, had proposed an alternative design modeled after the United Kingdom, with a foreign intelligence service, a joint intelligence committee staffed by career officials, and expanded analytical capacity. His proposal was set aside.

Goto of the opposition CRA identified another structural problem during committee hearings: the new council and the existing National Security Council share nearly identical membership. The prime minister chairs both; the same ministers sit on both. When the body curating intelligence and the body making policy overlap, the risk grows that information is shaped to fit preferred conclusions rather than to challenge them. 

Japan’s own record provides an instructive case. In 1991, the CIRO designed a public opinion survey on minesweeper deployment to the Persian Gulf with question framing that foregrounded “international contribution,” producing a 62 percent approval figure. That poll, in turn, was used to persuade a reluctant Prime Minister Kaifu Toshiki – and Japan’s first postwar overseas military dispatch followed.

What the Opposition Won – and What It Did Not

Goto’s party chose to vote in favor despite these concerns, and his post-vote explanation on April 24 laid out the reasoning with unusual candor. Because the bill does not grant new investigative powers over citizens, demanding new oversight solely for an internal restructuring would, in his view, lack proportionality. 

More practically, with the ruling coalition holding an overwhelming majority, outright opposition could not block passage – but negotiation could extract commitments.

What did the opposition secure through over 21 hours of deliberation? Chief Cabinet Secretary Kihara Minoru committed in formal answers to the committee that the government will compile a medium-to-long-term strategy document on intelligence activities, report it to the Diet, and make it public – including specific measures to prevent intelligence collection, provision, and requests that would unnecessarily violate privacy or compromise political neutrality. A senior Cabinet Intelligence official stated that records of National Intelligence Council proceedings will be created and preserved as official documents under public records management rules.

Most significantly, the chief cabinet secretary acknowledged that if future intelligence policies are developed that could constrain citizens’ rights – specifically, the establishment of a foreign intelligence service – the government will need to consider democratic oversight mechanisms, including parliamentary scrutiny.

These are meaningful concessions. But they are political commitments, not institutional safeguards. Goto himself acknowledged that appended resolutions lack legal binding force, though he argued that formal government answers to committee questions carry political obligation. This is true – ministerial statements on the record do constrain future government action. But political commitments are vulnerable to Cabinet reshuffles, changes in administration, and the gradual erosion of institutional memory. They are promises, not structural solutions.

The distinction matters because the concerns that prompted these commitments – the risk of politicized intelligence, the overlap between policy and intelligence curation, the absence of independent scrutiny – are structural features of the institutional design. Structural risks call for structural remedies.

The Oversight Consensus

Since the Snowden revelations, most comparable democracies have moved toward stronger parliamentary or independent oversight of intelligence activities. The United Kingdom substantially expanded its Intelligence and Security Committee of Parliament through the Justice and Security Act 2013. The United States has maintained congressional intelligence committees since the Church Committee reforms. Germany, France, and Australia have built parliamentary oversight into their intelligence architectures. The emerging consensus is that structured accountability improves intelligence quality – not least by institutionalizing challenge analysis that guards against groupthink.

The Five Eyes countries – Australia, Canada, New Zealand, the U.K., and the U.S. – have formalized this at the multilateral level. The Five Eyes Intelligence Oversight and Review Council brings together oversight bodies from all five nations, with a charter mandate to “encourage transparency to the largest extent possible to enhance public trust.” 

Japan is not a Five Eyes member, but it is an increasingly integrated intelligence partner, listed among the alliance’s Tier B cooperation countries. As that integration deepens, the absence of a domestic oversight mechanism becomes a structural misfit with the accountability standards that partners rely on when deciding what to share and under what conditions.

Rita Floyd has argued that securitization can be normatively legitimate when three conditions are met: the threat is objectively present, the response is proportionate, and the response is compatible with the community’s fundamental values. Foreign influence operations are real – the first condition is plausibly satisfied in the case of Japan’s intelligence reform. But proportionality requires asking whether better design was available. 

The Yachi proposal demonstrated that consolidation and oversight are not mutually exclusive. And the third condition is difficult to affirm when the architecture consolidates information under the same officials who make policy, with no independent check – a design that risks narrowing the range of options presented to decision-makers rather than diversifying them.

Rearticulation

Lene Hansen has identified “rearticulation” as the most constructive form of desecuritization: redefining an issue so it returns to the domain of normal politics. The structural problems in this intelligence reform legislation are not security questions. They are governance questions about how a democracy organizes the relationship between intelligence, executive power, and accountability.

The government’s committee answers point in this direction – acknowledging that future intelligence reforms touching citizens’ rights will require democratic oversight, and committing to public reporting on intelligence strategy. These commitments implicitly accept the principle that intelligence governance belongs in the domain of normal politics. The question is whether that principle will be honored through institutional design or left dependent on the political goodwill of successive administrations.

As the bill moves to the House of Councillors, that question remains open. The upper house has the leverage – and, if it chooses, the opportunity – to convert political promises into structural safeguards.
