Not Quite a Japanese CFIUS: What Japan’s New Investment Screening Regime

The JFIC is the visible half of the reform. The half that will move deals will take effect later. 

Executive Summary

Japan has built the institution it long lacked. The Japan Foreign Investment Committee (JFIC) held its first meeting on June 29, 2026, giving the nation a standing interagency forum for inbound investment screening. The committee is the most visible element of the reform and the only one already in force. It is also the least consequential.

The changes that will move transactions sit in the amendments to Japan’s Foreign Exchange and Foreign Trade Act (FEFTA) promulgated on June 5 as Act No. 30 of 2026[1]—four of which matter the most. Review now extends to certain foreign-to-foreign acquisitions where a Japanese business sits downstream. A post-closing call-in power, with a five-year lookback, reaches investments that never required a filing. Mitigation is codified so undertakings can be adjusted mid-review without resetting the clock. Anti-circumvention rules now capture nominee and agency structures. Most take effect within a year of promulgation, and the operative thresholds await Cabinet Office orders.

Two propositions follow for anyone planning a transaction. A Japanese filing question can now arise in a deal with no Japanese party on either side, and the absence of a filing obligation no longer marks the outer edge of regulatory exposure. The April recommendation against the Makino Milling Machine Co. (“Makino”) acquisition—an allied-jurisdiction sponsor and board-supported offer other regulators already cleared—confirms that Japanese authorities will act on the sensitivity of the target rather than the nationality of the buyer. Diligence, deal structure, and post-closing governance should be recalibrated now, before the implementing rules land.

Key Takeaways

1. Screen the structure, not just the target. Acquiring a non-Japanese company that indirectly holds a Japanese business may now require notification. For listed Japanese subsidiaries the trigger cannot be set below 1 percent; the statute sets no floor at all for unlisted ones.
2. Profile capital, not passports. Nationality alone no longer predicts scrutiny. Limited-partner composition, side-letter information rights, veto and consent rights, and state-linked relationships determine whether an investor will be treated as higher risk.
3. Closing is no longer the end of the analysis. A five-year reporting and intervention power reaches deals that never required a filing, including divestment. No filing confers safe harbor.
4. Treat mitigation as a planned deliverable. Because undertakings can now be amended mid-review, cooperation covenants, an express FEFTA condition precedent, and pre-negotiated remedies convert statutory flexibility into schedule certainty.
5. Track the reciprocal benefit. A robust Japanese regime strengthens the country’s case for Committee on Foreign Investment in the United States (CFIUS) “excepted foreign state” treatment. Japanese filers submitted more CFIUS declarations than any other country in 2024, so the stakes are commercial rather than symbolic.

A Committee but Not a New Authority

The JFIC’s secretariat sits at the Ministry of Finance. Prime Minister Sanae Takaichi has framed consistent cross-ministerial review as a means of improving predictability for foreign investors while serving economic security.

The JFIC is not a Japanese CFIUS in the strict sense. Unlike CFIUS, which is deployed as a geoeconomic instrument of statecraft in the US, the JFIC has no independent jurisdiction and blocking power. Screening authority remains with the minister of Finance and the competent sector minister, exercised through FEFTA’s existing recommendation-and-order machinery. The reform adds a statutory basis for input from across government and for intelligence assessments to reach the officials who decide. It arrived alongside legislation establishing a national intelligence bureau (enacted May 27).

The JFIC is co-chaired by the director-general of the Ministry of Finance’s International Bureau and a Cabinet councilor from the National Security Secretariat, with principal members from the foreign, economy, and defense ministries. The National Police Agency, Financial Services Agency, and eight further bodies sit as members, with the Cabinet Office as observer above a working-level steering group.

Three features bear on planning: meetings and minutes are, in principle, nonpublic; the interagency agreement prescribes no fixed schedule; and the consultation duty is calibrated rather than absolute. The Ministry of Finance and the competent minister must seek the views of the prime minister, foreign minister, and other authorities only where necessary. That is a shift from wholly discretionary practice but not a mandate that every filing circulate across government. How that judgment is exercised will shape review timelines more than any other variable.

What the Amendments Do

The substantive reform rests on four pillars, each awaiting subordinate legislation.

Indirect and foreign-to-foreign acquisitions

Where a foreign investor acquires, directly or indirectly, 50 percent or more of the voting rights in a non-Japanese entity that holds an interest in a Japanese company, or the right to appoint a majority of that entity’s directors, prior notification may be required if the filing criteria are met. The precise ownership threshold that will apply at the Japanese company level remains to be set by a Cabinet order. For listed companies, the statute prohibits any threshold below 1 percent; advisory materials indicate the government is considering 1 percent for higher-risk investors and 50 percent for others.[2] No minimum stake is specified for unlisted companies, leaving open the possibility that any interest will suffice.

Post-closing call-in

Authorities gain power to require reports, issue recommendations or orders, and impose emergency measures in respect of certain investments not subject to prior notification, with a five-year lookback and advisory materials pointing to acquisitions of 10 percent or more by higher-risk investors. This is a call-in exercised after the fact, not an extension of mandatory prior screening—which is why the absence of a filing obligation cannot be read as clearance.

Codified mitigation

Adjusting undertakings has generally required withdrawal and resubmission, resetting the statutory clock. The amendments permit a mid-review amendment proposing mitigation with the prohibition period running until fourteen days after acceptance where fewer than fourteen days remain. Changes to agreed measures after clearance require advance notice and renewed review.

Anti-circumvention

The rules now reach investments made by non-foreign investors for the account of, or under arrangements with, foreign investors. This closes the path in which a domestic or third-country vehicle held the Japanese interest while economic and governance benefits flowed to a foreign principal.

Sequence and Effective Dates

Date	Development	Operative effect
January 7, 2026	Council on Customs, Tariff, Foreign Exchange and Other Transactions reports on indirect acquisitions and non-notified deals	Policy basis for the bill
March 17	Cabinet submits amendment bill	—
April 22–30	Makino recommendation issued; transaction abandoned	Enforcement signal under existing law
May 29/June 5	National Diet passes the bill; Act No. 30 of 2026 promulgated	Interagency consultation provisions effective on promulgation
June 29	JFIC holds inaugural meeting	Committee operational
By June 2027	Remaining amendments take effect on a date set by Cabinet order	Thresholds, ex post powers, and anti-circumvention mechanics still to be fixed

The Makino Signal

Enforcement has hardened alongside the legislation. On April 22, the Ministry of Finance and Ministry of Economy, Trade and Industry (METI) recommended against the acquisition of Makino by a vehicle of the Seoul-based private equity firm MBK Partners, citing the proposal to take Makino wholly owned and the wide use of its machine tools by Japanese defense manufacturers. MBK abandoned the transaction on April 30. Practitioners describe this as the first publicly disclosed cease-and-desist recommendation since the 2017 FEFTA amendments and only the second stop recommendation since the 2008 Electric Power Development case.

The features are instructive: a listed manufacturer of dual-use rather than defense-specific equipment, though in a sector designated core in 2020; a board that had endorsed the roughly ¥275 billion offer; an acquirer from an allied jurisdiction; and a ten-month review concluding after other jurisdictions had cleared. MBK’s acquisition of Altemira Holdings was reportedly cleared weeks later. One sponsor, a stop, and a clearance in short succession: outcomes turn on the target’s technology, customer base, and perceived defense sensitivity, not on categorical investor blacklisting.

Convergence—and Reciprocal Opportunity

Japan’s notification-driven, high-volume regime had roughly 2,900 prior notifications in fiscal year 2024, processed through an administrative front end. CFIUS reviewed 347 filings in calendar year 2025 (207 notices and 140 declarations), broadly consistent with recent years’ data. The JFIC improves analytical inputs; it does not convert a high-volume notification system into a low-volume investigative one. Convergence with CFIUS is therefore substantive rather than procedural, centered on beneficial ownership and post-closing reach. The same emphases run through the European Union’s (EU) 2019 screening regulation and the national regimes in Germany, France, Italy, and the Netherlands, though the EU’s decentralized model handles multistate spillovers better, while Japan’s unified body offers single-jurisdiction consistency.

One consequence is easily overlooked. CFIUS may designate “excepted foreign states” whose screening processes it judges robust and coordinated with the US, and investors from those states obtain relief from certain mandatory filings and from CFIUS jurisdiction over some noncontrolling and real estate transactions. Only the Five Eyes partners (Australia, Canada, New Zealand, the United Kingdom, and the US) qualify today. A strengthened FEFTA regime, standing interagency committee, and new intelligence bureau together improve Japan’s case. Japanese filers led all countries in CFIUS declarations in 2024, so the value of such a designation would be commercially significant. Groups with capital moving in both directions should be modeling that possibility now.

What This Means for Transaction Planning

Diligence moves upstream. Any target group holding Japanese subsidiaries requires Japanese analysis, and internal reorganizations or transfers between fund entities may trigger notification.

Investor profiling must extend beyond the acquiring vehicle to the full capital structure: limited-partner composition, side letters conferring information or governance rights, veto and consent rights, and arrangements with state-linked entities. An investor that appears wholly private on the face of the documents still may be treated as higher risk if a significant limited partner is a sovereign wealth fund, a side letter obliges disclosure of sensitive technical information to a foreign government, or governance lets a foreign state actor influence the Japanese business. Identifying these features early preserves the option to restructure before filing rather than under review.

Mitigation should be designed rather than improvised. Documents should carry cooperation covenants obliging the investor to negotiate and implement undertakings in good faith and should make FEFTA clearance—or implementation of agreed measures—an express condition precedent wherever a Japanese nexus exists. In sensitive cases the contours of potential mitigation measures (e.g., information firewalls, board composition limits, supply-chain assurances) are worth pre-negotiating so a proposal can be tabled within the review period.

Nominee and agency structures require scrutiny and a documentary record. Any trust, agency, or contractual arrangement capable of being characterized as holding a Japanese interest for a foreign principal should be tested against the new rules and the acquiring entity’s independent economic and decision-making substance recorded contemporaneously.

Post-closing governance now carries regulatory weight. With call-in available for five years, integration decisions (e.g., technology transfer, personnel access, supply commitments to defense-linked customers) are taken in the shadow of a live review power.

Unresolved

Cabinet orders will fix thresholds, define the higher-risk investor category, delimit ex post powers, and specify anti-circumvention mechanics, so any assessment of practical burden is provisional. Practice will answer whether formalized consultation produces more thorough reviews or merely friction, differentiated scrutiny survives several thousand filings a year, and Makino proves threshold-setting or particular to its facts.

Japan remains open, and most filings will clear without incident. But transactions touching capabilities Japan regards as core now require the disciplined national security analysis long standard in CFIUS practice—conducted earlier and extended to ownership structures that until recently sat outside the frame.

How BRG Can Help

BRG’s Global Trade and Compliance practice advises investors, sponsors, and their counsel on investment screening across the US, Japan, the EU, and the United Kingdom. In relation to the Japanese reform, our work typically includes:

• Jurisdictional mapping across a target group to identify Japanese nexus, including downstream subsidiaries and intra-fund transfers, before terms are agreed.
• Beneficial ownership and investor-risk profiling, tracing limited partners, side-letter rights, and state linkages to anticipate the scrutiny a transaction will attract.
• Mitigation design, negotiation support, and independent monitoring drawing on our experience serving as monitor and compliance adviser under CFIUS agreements.
• Post-closing compliance and call-in readiness, including governance protocols, technology-access controls, and documentation that will withstand retrospective review.
• Support development of economic-security regulatory strategy for groups managing CFIUS, FEFTA, and EU screening in parallel, including positioning for the reciprocal benefits of an “excepted foreign state” determination.
