Foreign Agents Beware—Tokyo Moves

Japan is racing to plug huge gaps in its defenses against foreign spies, and the fight over how far to go should matter to every American who cares about national security and freedom.

Story Snapshot

Japan is only now building a real counter-espionage system, after decades as a “spy paradise” with no true anti-spy law.
A new National Intelligence Council and Bureau will centralize power to fight foreign spying, terrorism, and disinformation.
Future laws will likely copy U.S.-style foreign agent rules and tougher penalties on corporate and research espionage.
Left-leaning critics warn of a “surveillance state,” echoing the same privacy fights Americans see at home.

Japan Closes Its “Spy Paradise” Gap

For years, allies quietly called Japan a “spy paradise” because there was no independent anti-espionage law that made general spying a crime. Foreign operatives could fish for military, tech, and economic secrets in a major U.S. partner with limited risk. Japan relied on secrecy rules like the 2013 Act on the Protection of Specially Designated Secrets, which protects classified documents but does not clearly cover broad spying activity. That legal gap left America’s most important Asian ally softer than the United States, the United Kingdom, or Australia when it came to counter-espionage.

Prime Minister Sanae Takaichi’s government has moved to change that, tying the effort to rising threats from China, Russia, and North Korea. Japanese officials say better intelligence is needed to deter foreign spies, safeguard key technologies, and counter hybrid warfare tactics like cyber attacks and disinformation campaigns. Conservative lawmakers inside Japan pushed for reforms after experts warned that hostile states were exploiting weak laws and fragmented agencies to run influence operations and economic theft on Japanese soil. This concern mirrors long-standing U.S. warnings about Beijing and Moscow’s global espionage campaigns.

National Intelligence Council: A New Command Center

On May 27, 2026, Japan’s Diet passed legislation to create a National Intelligence Council and a supporting secretariat. Under the reform, the National Intelligence Bureau will sit at the center of Japan’s intelligence system, integrating information from many ministries and reporting to the council, which is chaired by the prime minister. The aim is to break down long-standing silos, where separate agencies failed to share data on foreign spies, terrorism risks, or economic security threats. For U.S. readers, this looks similar to the push after 9/11 to improve coordination among agencies.

The new council will set unified strategy for foreign intelligence, counterintelligence, economic security, and information warfare. One core mission is to spot and stop disinformation and manipulation campaigns led by foreign agents before they shape Japan’s politics or weaken its alliances. For Washington, that matters because Japan hosts U.S. forces and anchors the free world’s posture in the Indo-Pacific. A more capable Japanese service can share better intelligence on Chinese and Russian activities, help guard supply chains for advanced chips, and support joint operations. Stronger Japanese laws also send a clear message to Beijing that the days of easy spying are ending.

Next Step: A Real Anti-Spy Law And Foreign Agent Rules

The intelligence overhaul is only stage one. Takaichi has pledged to “speedily draft” a new law on “spy prevention,” and ruling parties have written rapid enactment of anti-spy measures into their coalition deal. Current plans include tougher penalties for espionage carried out for foreign powers and a legal framework similar to America’s Foreign Agents Registration Act, forcing people who act for foreign interests to report their funding and activities. An expert panel on foreign anti-espionage laws is due to meet and compare how democracies balance security with civil liberties. Those findings will guide bills expected in the autumn Diet session that could become Japan’s first true anti-spy statute.

Japan already passed a law in 2025 to protect “economic security information,” adding a security clearance system to stop leaks of sensitive business and technology data. But that law focuses on economic secrets only and does not criminalize general intelligence work or spying, leaving gaps when hostile services target political parties, activists, or regular citizens. New reforms would likely add criminal penalties for corporate and research espionage, forcing companies and universities to take foreign spying more seriously. U.S. firms operating in Japan may welcome stronger protection against theft, but they will also need to watch compliance rules, just as they do at home under U.S. national security law.

Rights Fears And “Surveillance State” Warnings

Japan’s left and human rights groups are already sounding alarms that should feel familiar to American conservatives. Human Rights Watch warned that Takaichi’s promise to move fast, and past secrecy laws, raise serious concerns for free speech, media freedom, and whistleblower protection. Opposition leader Fukushima Mizuho has called the intelligence reform a step toward a “surveillance state” and claimed new bodies could be used for purposes far beyond counter-espionage. Some critics and media outlets say tightened secrecy rules might be used to silence journalists or block exposure of government wrongdoing.

These fights have pushed lawmakers to add formal privacy language. Committees in both houses passed a resolution saying personal information and privacy must not be unnecessarily infringed and that intelligence gathering should not undermine political neutrality. Critics still worry that future anti-spy bills could be broad enough to criminalize normal behavior. One lawmaker even warned that the law might threaten “oshikatsu,” Japan’s fan culture around pop idols, if supporting a foreign star could be twisted into foreign influence. For U.S. readers, this echoes how vague “disinformation” or “foreign interference” labels at home can be misused to target free speech.

What This Means For America And The Free World

For the United States, a stronger Japanese shield against foreign spies is a clear strategic win. China has already expanded its own counter-espionage law, giving authorities vast power to target foreigners and widen the definition of “national security.” If Japan stays weak, hostile regimes gain an easy back door into advanced technology, finance networks, and military planning that support U.S. power in Asia. By building a real intelligence council and preparing robust anti-spy laws, Tokyo is finally stepping into its role as a full partner in defending the free world’s infrastructure and information.

At the same time, American conservatives know how quickly “national security” can become a weapon against political enemies if leftists and bureaucrats are unchecked. Japan’s coming debate over how far its anti-spy law should reach is a reminder to watch the balance at home too. The core lesson is simple: free nations need tough tools to stop foreign spies, but they must write clear laws, guard free speech, and resist any move to turn intelligence agencies into tools of domestic control. That fight is global, and it will not end with one bill in Tokyo.
