Foreign Investment Screening in Japan: FEFTA Prior Notification Explained

Japan screens inward foreign investment under the Foreign Exchange and Foreign Trade Act, and in designated sectors the screening is suspensory: you file a prior notification and wait out a review before you can complete. The threshold for the most sensitive sectors is as low as one percent. For anyone acquiring into a Japanese company in a covered area, this is not paperwork that follows the deal; it is a condition on whether the deal can close.

This is the step foreign investors most often discover late. The Foreign Exchange and Foreign Trade Act, FEFTA (外国為替及び外国貿易法), is Japan’s counterpart to CFIUS in the United States, and like CFIUS it has moved to the center of deal planning as economic security has risen up the agenda. Understanding it early is the difference between a clean timeline and a transaction that stalls, or is forced open after the fact.

What follows is what triggers a filing, how the two-week clock actually works, which sectors are caught, and where the review turns from an administrative step into a public affairs question. The regime is run by the Ministry of Finance together with the sector ministry that oversees the target’s business.

Two tracks: prior notification versus post-completion report

FEFTA splits inward direct investment into two very different tracks, and which one you are on decides whether the review is a gate or a formality.

Track	Legal basis	When	Timing	Filings/year
Prior notification	Art. 27	designated sectors, before completing	2-week waiting period (extendable)	~2,871
Post-completion report	Art. 55-5	most other investment, after completing	within 1 month	~4,850

Prior notification is the screening track. It applies to investments in designated business sectors and must be filed, and cleared, before the transaction completes. A statutory waiting period runs, published at two weeks, during which the investor may not proceed.

Post-completion reporting is the routine track. For investment that falls outside the designated sectors, the obligation is simply to report after the fact, within a month. No waiting, no gate.

The ratio between the two, roughly 2,871 prior notifications against 4,850 post-completion reports a year, tells the story: most inward investment into Japan is not pre-screened, but the slice that is happens to be exactly the sectors a foreign strategic or financial investor is most likely to find interesting.

What triggers a prior notification

Two conditions have to coincide: the target is in a designated sector, and the investment crosses the threshold.

The designated sectors are a published list, with a narrower set of core sectors carrying the strictest treatment. The list covers areas seen as bearing on national security and public order: weapons, aircraft, space and nuclear, dual-use technologies, cybersecurity, and critical infrastructure such as energy, telecommunications, and certain utilities, among others. It is specific, and it is revised periodically, so whether a particular target sits inside it is a factual question to settle at the start of a deal.

The threshold is where the regime bites harder than newcomers expect. The 2019-2020 reform cut the trigger for acquiring shares in a listed company in a core sector from 10 percent to 1 percent. A one-percent stake can be enough to require prior notification. The same reform introduced exemption schemes so that passive institutional investors, those who will not seek board representation or access to sensitive information and who accept the attaching conditions, can be relieved of the prior-notification requirement. Whether a given investor qualifies is a specific analysis, and it is consequential: get it right and a passive stake is unencumbered; get it wrong and it is a notifiable, suspensory transaction.

How the clock really works

The published waiting period is two weeks from acceptance of the notification, and for a clean, clearly-non-sensitive filing that is realistic. But two things make the two weeks a floor rather than a fixed duration.

First, the authorities can extend the review period for cases that warrant closer examination, and for genuinely sensitive transactions they do. The two weeks is the fast case, not the guaranteed case.

Second, and more important, the clock runs before completion. This is a suspensory condition on the transaction: until the period expires without objection, or clears with conditions, the investor cannot proceed. Treating FEFTA as a post-signing administrative step is the classic error. It belongs in the conditions precedent, alongside the other regulatory clearances, because it can hold up the closing and, in a contested case, reshape the deal.

What is at stake if you get it wrong

FEFTA prior notification is not optional and not curable after the fact by apology. Completing a covered investment without the required notification, or in breach of the waiting period or of conditions attached to a clearance, exposes the parties to orders to unwind or modify the investment and to penalties. For an acquirer, an unwind order against a completed transaction is close to the worst regulatory outcome there is. This is precisely why the clearance sits in the deal conditions and why the sector-and-threshold analysis is front-loaded.

Where this becomes a public affairs question

The mechanics of filing are transaction work, and deal counsel handle them. The public affairs questions sit around the review itself, and they are real ones as economic security policy tightens.

Whether a sector is designated, how the core-sector list is drawn, what conditions a clearance carries, and how the authorities read a novel transaction structure are all matters of policy and administrative judgment, not fixed mechanics, and they are moving. An investor in a genuinely borderline case, a target whose classification is arguable, a structure the rules did not anticipate, a sector under active review, is not simply filling in a form; it is engaging with an authority exercising discretion in a politically charged area. Making that case well, framing the transaction accurately, addressing the security concern directly, being a known and credible counterparty rather than an opaque foreign acquirer, is public affairs work, and it is where sophisticated investors distinguish themselves from those who arrive with only a filing.

How to plan it

• Settle the sector-and-threshold question first. Whether the target is designated, and whether you cross the trigger, decides whether you are on the suspensory track at all.
• Put FEFTA clearance in the conditions precedent. The waiting period runs before completion, so it can delay or block the closing if it is left to the end.
• Treat two weeks as a floor. For sensitive cases the review extends; build schedule contingency.
• Test the exemption carefully if you are a passive investor. The 1 percent core-sector trigger means small stakes can be caught; the exemption relieves it only on conditions.
• Engage on the review, not just the filing, in a borderline case. Classification and conditions involve judgment, and how you frame the transaction matters.

Why this matters for public affairs in Japan

Foreign investment screening looks like transaction plumbing, and for a clean deal in an uncovered sector it is. But FEFTA sits on top of Japan’s economic-security agenda, one of the most active and politically sensitive areas of policy, and the designations, thresholds, and conditions that decide whether a deal is screened, and on what terms, are set and revised through that policy process. For an investor whose transaction turns on how a sector is classified or how a security concern is weighed, the review is downstream of decisions that can be engaged. Knowing where the administrative step ends and the policy question begins, and being able to make the case in the second, is what separates a deal that clears from one that stalls.
