JFTC Dawn Raids in Japan (2026): What Foreign Businesses Must Do During an Antitrust Inspection

Japan antitrust dawn raids are becoming a sharper operational risk for foreign multinationals as the Japan Fair Trade Commission (JFTC) steps up enforcement and deepens coordination with authorities such as the U.S. Department of Justice and the European Commission. For in-house counsel, compliance officers and regional general counsel, the first hours of an unannounced on-site inspection can determine whether a company preserves its legal position or forfeits it. This guide sets out a practical, minute-by-minute response framework grounded in the Antimonopoly Act and JFTC procedure, with specific attention to cross-border evidence preservation, leniency coordination and privilege. It is written for non-Japanese businesses that need to know exactly what to do when inspectors arrive.

What this guide covers and a quick checklist

When the JFTC arrives, your goal is to cooperate lawfully while protecting the company’s rights, preserving evidence correctly and preventing avoidable missteps by staff. Japan antitrust dawn raids are typically administrative inspections conducted under statutory authority (Article 47 of the Antimonopoly Act), which means refusal and obstruction carry their own risks, including criminal penalties, but it also means the inspectors operate within defined limits you can and should document.

Quick “if you have 10 minutes” checklist

1. Appoint a single on-site response lead immediately.
2. Check and record the inspectors’ examiner ID cards and the written notice of the suspected violation, and confirm whether the inspection is an administrative inspection or a criminal investigation under a judicial warrant.
3. Notify the General Counsel, Chief Compliance Officer and external counsel at once. NOTE: Do not ask the inspectors to delay the inspection until counsel arrives; counsel may attend, but the JFTC is not required to wait.
4. Issue an immediate litigation hold and stop all document deletion and auto-purge.
5. Instruct employees to stay calm, remain polite and not volunteer statements.
6. Assign a “shadow” to accompany each inspector throughout the premises.
7. Keep a contemporaneous inspection log of every room, device and document reviewed or taken.
8. Request the JFTC’s determination procedure for properly labelled and stored lawyer-client communications before the submission order is issued, and flag third-party materials.
9. Check every retained item against the inventory attached to the submission order and retention notice.
10. Preserve cross-border electronic data and notify parent-company and foreign counsel.

1) What to expect when the JFTC arrives: legal powers and practical conduct

The JFTC’s enforcement authority flows from the Antimonopoly Act (formally, the Act on Prohibition of Private Monopolization and Maintenance of Fair Trade), Japan’s principal competition statute. Under Article 47 of the Act, the JFTC may enter business premises and inspect books, documents and other items, order the holders of items to submit them and retain the submitted items, order persons to appear for questioning, and require reports relevant to a suspected violation such as cartel conduct, bid-rigging or abuse of a superior bargaining position. These powers are backed by criminal penalties for non-compliance (Article 94), but inspectors cannot use physical force to overcome a refusal. The official English site of the Japan Fair Trade Commission and the Ministry of Justice’s Japanese Law Translation portal set out the statutory basis for these powers.

Understanding the character of the inspection matters. Most JFTC inspections are administrative investigations under Article 47. Separately, in serious and egregious cases (typically price cartels and bid-rigging), the JFTC may conduct a criminal investigation under Articles 101 and 102, including on-site visits, searches and seizures under warrants issued by a judge, and then file a criminal accusation with the Prosecutor-General. The Act provides that the Article 47 administrative powers must not be interpreted as being granted for criminal investigation, so the first question is which type of investigation is under way. That dual-track possibility is one reason why the way your team behaves during the first hours of a JFTC inspection has consequences far beyond the immediate visit.

Who may attend

A JFTC inspection team typically comprises several investigators who arrive without advance warning, usually at the start of the business day. Depending on the matter, the team may include officials with technical or forensic capability to examine digital devices. In a criminal investigation, JFTC officials themselves conduct searches and seizures under judicial warrants; the case passes to prosecutors after the JFTC files an accusation. Interpreters may be present or requested; if your staff are more comfortable in another language, note this and ensure accurate translation, but do not use language difficulties as a pretext for obstruction.

Inspector rights versus company rights

Inspectors may enter any place they reasonably consider necessary for the investigation, which can include employees’ homes, inspect records, and order the submission and retention of items, including personal items such as notebooks and mobile phones. Refusal, obstruction or evasion is punishable by imprisonment of up to one year or a fine of up to JPY 3 million (Article 94), although inspectors cannot physically force compliance.

The company retains important rights too: to see the inspectors’ examiner ID cards and receive a written notice stating the case name, a summary of the suspected violation and the applicable provisions; to have the person in charge of the premises present; to receive the inventory of retained items; to inspect and copy retained items from the day after the inspection; to request the determination procedure for qualifying lawyer-client communications; to raise scope concerns; and to file a written objection with the JFTC within one week of an examiner’s measure.

Knowing the boundary between these two sets of rights is the single most useful piece of preparation a compliance team can have before Japan antitrust dawn raids ever occur.

Common inspector tactics and requests

• Simultaneous site entry. Inspections are often coordinated across multiple offices at once to prevent coordination between locations or destruction of evidence.
• Immediate access to key custodians. Inspectors frequently ask to see the devices and files of senior executives and sales personnel.
• Informal questioning. Casual conversation can generate damaging admissions; staff should be briefed in advance to be courteous but to defer substantive questions to counsel.
• Copying of electronic data. Expect orders to submit email, shared-drive and messaging data copied onto storage media (and, where necessary, the devices themselves). Same-day copies of retained documents for the company’s own use are not a right, but may be allowed for items needed for daily business.

2) First 2 hours, the immediate-actions playbook for Japan antitrust dawn raids

The opening phase of any inspection is where most damage is done or prevented. The following sequence answers the most common question in-house teams ask: what should my company do immediately if the JFTC arrives?

Designated response lead and communications protocol

Step 1, Activate the response plan. Reception and security should have a standing instruction: on arrival of regulators, call the designated response lead and the legal department without delay, and take the inspectors to the person in charge of the premises without obstructing or delaying the start of the inspection. Counsel may attend at the company’s request to the extent this does not hinder the inspection, but attendance is not a right and the inspectors are not required to wait for counsel to arrive. A sample reception script: “Thank you. I am contacting our legal team now. Let me take you to [name], who is in charge of these premises.”

Step 2, Verify and record. The response lead checks the inspectors’ examiner ID cards, receives the written notice setting out the case name, the summary of the suspected violation and the applicable provisions, and confirms whether this is an administrative inspection under Article 47 or a criminal investigation under a judicial warrant. Record the names, titles and arrival time of every inspector and the stated scope.

Step 3, Escalate immediately. Notify the General Counsel, Chief Compliance Officer and external competition counsel. For foreign groups, alert parent-company legal leadership and, where parallel exposure exists, counsel in other jurisdictions. Speed here is essential because leniency timing can turn on it.

Step 4, Freeze destruction. Issue a company-wide litigation hold. Suspend automatic email and file deletion policies and instruct IT to preserve server states. Destroying, altering or concealing evidence during an inspection is among the gravest mistakes a company can make and can escalate an administrative matter into a far more serious one.

Managing on-site staff and C-level executives

Brief employees quickly and consistently: be polite and cooperate with lawful requests; do not volunteer information; do not guess or speculate; defer substantive questions to counsel; and do not discuss the matter with colleagues or externally. Executives are frequent targets of informal questioning and should be reminded that off-the-cuff remarks can become part of the record. Where staff are interviewed, note that the JFTC does not permit third parties, including company representatives and counsel, to attend interviews, and does not permit recording, note-taking by the interviewee during the interview or copies of the statement record. Interviewees may, however, contact counsel during breaks. The company should debrief interviewees promptly afterwards and keep its own record. Employees of a leniency applicant may, on request, prepare a memo of their statement immediately after the interview.

Handling physical inspection and retention of items

Assign a knowledgeable “shadow” to accompany each inspector. The shadow’s job is to observe, take notes and maintain the inspection log, not to interfere. The log should record each location entered, each device accessed, each document reviewed or copied, and the time of each event. When items are retained, inspectors present each item one by one to the person in charge and check it against the inventory; the shadow should take part in that check and record any discrepancies. This contemporaneous record is invaluable later for assessing scope, challenging over-reach and coordinating with counsel in other jurisdictions.

3) What the JFTC can and cannot require and retain, documents, digital data and devices

The scope of what inspectors may take during Japan antitrust dawn raids is defined by the subject matter of the inspection and the statutory powers under the Antimonopoly Act. In practice, inspectors order the submission of originals in their current state, such as documents, meeting notes, pricing records, notebooks and mobile phones, and of electronic files and emails copied onto storage media (or, where necessary, the computers themselves), and then retain them. Digital evidence is central to modern competition investigations, so expect close attention to email systems, shared drives, chat applications and personal devices used for business.

Submission orders, retention notices and inventories

For items retained, the inspectors issue a submission order and a retention notice, each with an inventory identifying the items, and check each item against the inventory in front of the person in charge. Review the inventory carefully; the owner of retained items may also request a copy of the inventory. Documents needed for daily business may be copied on the day to the extent this does not hinder the inspection, and retained items can be inspected and copied from the following day by arrangement with the JFTC. A precise retention inventory protects the company in two ways: it establishes the chain of custody, and it clarifies exactly what the authority holds, information you will need when preparing a defence, when assessing leniency and when responding to parallel requests from foreign regulators.

Handling privileged or third-party materials

Before material leaves the premises, your shadow and counsel should attempt to identify documents that may be protected or that belong to third parties or fall outside the inspection’s scope. Where confidentiality or scope concerns arise, raise them promptly and in writing rather than allowing the issue to pass silently. For lawyer-client communications covered by the JFTC’s determination procedure (see section 6), the company must tell the examiner orally that it wishes to use the procedure and submit a written request on the day, before the submission order is issued, and then file a summary document within two weeks. For other concerns, raising and documenting the objection preserves arguments for later; a formal objection to an examiner’s measure must be filed in writing within one week.

Creating an inspection log

The inspection log is the backbone of a defensible response. It should capture: the inspectors’ identities and credentials; the stated scope; a room-by-room and device-by-device account; copies made and originals retained; any questions asked and by whom; and any objections raised. Maintain a parallel list of retained items cross-referenced to the official inventories. Treat the log as a potentially discoverable record and keep it factual and neutral.

4) Handling cross-border evidence and data, foreign documents, cloud and ESI

For multinationals, the hardest questions in Japan antitrust dawn raids concern evidence that physically or legally sits outside Japan: data on overseas servers, documents held by a foreign parent, and electronically stored information in global cloud environments. Mishandling this material can create liability in multiple jurisdictions at once.

Can the JFTC require documents located outside Japan?

As a practical and jurisdictional matter, the JFTC’s compulsory powers are territorial. It does not have unilateral authority to compel the production of documents physically located abroad in the same way it can inspect premises in Japan. Instead, it may request voluntary production and rely on international cooperation mechanisms and information-sharing arrangements with foreign competition authorities, including bilateral antitrust cooperation agreements with the United States (1999), the European Community (2003) and Canada (2005). The International Competition Network describes the cooperation norms that increasingly underpin these cross-border investigations. The key takeaways for foreign businesses: do not assume foreign-located data is beyond reach, and do not rush to transfer or move data in a way that could look like concealment.

Immediate technical steps for ESI preservation

• Suspend auto-deletion. Halt retention policies that purge email, chat and file data across all relevant systems, including cloud tenants.
• Preserve in place. Where possible, preserve data in its current location through forensic snapshots or legal holds rather than mass-exporting it, which can raise data-transfer and spoliation concerns.
• Engage qualified forensics. Use experienced forensic specialists to image devices and systems so that integrity and chain of custody are maintained.
• Map the data. Identify where relevant data physically resides and which jurisdictions’ export, privacy and blocking rules may apply before any cross-border movement.

Use of international cooperation channels

Where the JFTC seeks foreign evidence, it may do so through cooperation requests between authorities rather than direct compulsion abroad. Companies caught in these situations should coordinate early across jurisdictions so that production in one forum does not inadvertently waive protections or create exposure in another. Many practitioners expect the use of inter-agency cooperation channels to intensify as competition regulators continue to align their enforcement against cross-border conduct.

5) Leniency, immunity and self-reporting in Japan, can a foreign parent apply?

Japan operates a corporate leniency system under the Antimonopoly Act, administered by the JFTC, which can reduce or eliminate surcharges for companies that come forward and cooperate in cartel and bid-rigging cases (including purchasing cartels); it does not apply to other violations such as abuse of a superior bargaining position. For foreign groups, the decisive question after Japan antitrust dawn raids is frequently whether and when to seek leniency, and that decision cannot be made in isolation from parallel exposure in the United States, the European Union and elsewhere.

Eligibility criteria and timing

Leniency generally rewards early reporting and genuine, continuing cooperation, with the most favourable treatment reserved for applicants who come forward first and provide meaningful evidence. Following amendments to the Antimonopoly Act that took effect on 25 December 2020, Japan’s system also allows the JFTC to adjust surcharge reductions based on the value of a company’s cooperation, in addition to the order of application. Because standing and order of application matter so much, the moment an inspection begins, or, ideally, before, the company should assess its leniency position. Delay can be fatal to the best outcomes, which is why the escalation step in the first hours of a raid is so important.

Coordination with other authorities

A foreign parent facing potential exposure in several jurisdictions should treat leniency as a multi-jurisdictional strategic decision. The U.S. Department of Justice Antitrust Division operates its own Corporate Leniency Program with a marker system, and a company that qualifies in one jurisdiction will often want to pursue leniency in others on a coordinated timeline. Coordinated applications can maximise the benefit of self-reporting, but they must be sequenced carefully so that disclosures in one forum do not undercut the company’s position in another.

Risks of joint applications, parent versus local affiliate

Groups must decide carefully who applies: the parent, the Japanese subsidiary, or the group as a whole. Interests can diverge, for example, where only certain entities or individuals were involved in the conduct, and the structure of an application affects the scope of protection and the obligations that flow from it. These choices should be made with counsel experienced in both Japanese and foreign leniency regimes before any disclosure is made.

6) Internal investigations, privilege and communications with counsel

Once the inspectors leave, the company’s internal investigation becomes central. Done well, it clarifies exposure and underpins leniency and remediation; done poorly, it creates discoverable records and new risk. Privilege is the thread running through all of it, and the Japanese privilege landscape differs materially from common-law systems.

The privilege landscape in Japan

Japan does not recognise legal professional privilege to the same broad extent as common-law jurisdictions. In the competition context, since 25 December 2020 the JFTC has operated a determination procedure (hanbetsu tetsuzuki): materials recording confidential communications between a company and a lawyer concerning legal advice on suspected cartel or bid-rigging conduct are returned to the company without investigators reviewing their contents, if prescribed conditions are met. The procedure applies only to administrative investigations of conduct eligible for leniency; it does not apply to criminal investigations or to other violations such as private monopolisation or unfair trade practices. The lawyer must be qualified under Japan’s Attorneys Act and act independently of the company. Communications with foreign lawyers (including registered foreign lawyers in Japan) and with employed in-house counsel are not covered, unless the in-house counsel has been placed, by written instruction, outside the company’s chain of command to act independently. This protection is narrow and does not extend to the breadth of attorney-client privilege familiar in common-law systems. Foreign companies should not assume that internal communications in Japan enjoy the same shield as abroad.

The safest course is to route sensitive legal analysis through Japanese-qualified external counsel and to document the basis for any claim of protection clearly. Sharing such communications with foreign counsel or certain group-company officers does not necessarily defeat protection, provided the need to share can be explained.

Best practices for logging protected material

Maintain a log identifying documents over which protection is asserted, the basis for the claim and the authors and recipients, and ensure sensitive materials are handled in accordance with the JFTC’s prescribed procedures so that any available protection is not lost. Protection depends on preparation before any inspection: covered materials must be labelled to show that they record such communications (the JFTC recommends the label “公取審査規則特定通信”, meaning “JFTC Investigation Rules: Specified Communication”, or “公取審査規則第23条の2第1項該当”), stored in a location managed by the legal function and separated from other materials, and accessible only to those who need to know. Emails must be exchanged through a dedicated mail account with the label in the subject line. Generic labels such as “attorney-client privilege” are not sufficient on their own. A disciplined approach supports prompt assertion of protection during a raid and in later proceedings, and signals good-faith handling of sensitive material.

Cross-border counsel coordination

Because the rules protecting legal communications differ sharply between Japan, the United States and the European Union, groups facing parallel investigations should coordinate so that a document protected in one jurisdiction is not inadvertently exposed in another. U.S. privilege rules, for example, may protect in-house legal communications that Japanese practice would not. Managing this interface requires counsel who understand both systems.

When to stop or continue internal interviews

Internal interviews can be essential to understanding the facts, but they create records and can raise employee-rights considerations. Decide, with counsel, whether and when interviews should proceed, how they are recorded, and whether individual employees need separate representation. Where leniency timing is live, interviews should be sequenced so they support, rather than complicate, the company’s cooperation strategy.

7) Parallel and coordinated investigations, DOJ, FTC, EC and beyond

Few significant competition matters involving multinationals remain confined to a single jurisdiction. The modern reality of Japan antitrust dawn raids is that they often run alongside, or trigger, investigations by the U.S. Department of Justice, the European Commission and other authorities, which increasingly share information and coordinate timing.

Practical steps for sharing or withholding information

Any decision to produce information to one authority must be assessed for its effect in every other forum. Some authorities request waivers that allow them to share information produced to another regulator; granting or refusing such waivers is a strategic decision with real consequences. Treat every disclosure as potentially visible to every other investigating authority.

Strategies for coordinated leniency

Where leniency is in play in multiple jurisdictions, applications should be planned on a synchronised timeline so that the company secures the best available position in each. The marker systems operated by authorities such as the DOJ reward speed and consistency, and inconsistent accounts across jurisdictions can be damaging.

Managing regulatory requests across time zones

Parallel investigations generate overlapping deadlines across time zones and languages. Establish a single coordinating team, typically led by the General Counsel with external counsel in each relevant jurisdiction, to track requests, deadlines and disclosures in one place, ensuring the company speaks with one coherent voice.

8) Comparison table: JFTC vs DOJ vs EC, powers, approach and document seizure

The table below summarises key differences foreign businesses should keep in mind when managing exposure across jurisdictions. The practical implication is that a single course of conduct can attract administrative, civil and criminal consequences in different systems, so a coordinated, multi-jurisdictional response is essential.

9) Practical templates and checklists for a dawn raid response

Preparation is what separates a controlled response from chaos. The following assets should be built, approved by counsel and kept accessible to the response team before any inspection occurs. They can be maintained as ready-to-use templates for your dawn raid response plan.

• Internal notification email. A pre-drafted message to the General Counsel, Chief Compliance Officer, IT, security, local counsel and parent-company counsel, triggered the moment inspectors arrive.
• Reception and security script. Short, neutral language for front-line staff to use while legal is summoned, without delaying the start of the inspection.
• Preservation notice to employees and IT. A litigation-hold instruction suspending deletion and requiring preservation of documents, emails, chat data and devices.
• Inventory review checklist. A checklist for checking retained items against the JFTC’s inventory and identifying documents needed for daily business that should be copied.
• Determination procedure request. The JFTC’s request form for the determination procedure, completed in advance as far as possible, together with draft summary documents for covered materials.
• Chain-of-custody form. A standard record tracking each retained or imaged item from the premises onward.
• Inspection log template. A structured sheet for recording rooms entered, devices accessed, documents reviewed and objections raised.

Conclusion and next steps

Japan antitrust dawn raids reward preparation and punish improvisation. Foreign businesses that have a tested response plan, a designated lead, a reception script, an automatic litigation hold, trained staff, a disciplined inspection log and pre-approved templates, are far better placed to protect their legal position, preserve cross-border evidence correctly and make sound, timely leniency decisions. Because these inspections increasingly run in parallel with investigations by the DOJ, the European Commission and other authorities, the response must be coordinated across jurisdictions from the first hour. If your organisation has exposure in Japan, now is the time to build and rehearse that plan, and to secure experienced cross-border competition counsel who can act the moment inspectors arrive.
