Japan Criminal Records Search: Cases & Public Records

“Criminal record” can mean several different things in Japan

How Japan’s official Certificate of Criminal Record works

Japan’s official criminal-record certificate is commonly called a police certificate or Certificate of Criminal Record.

The National Police Agency’s certificate format states that the certificate is based on a search of fingerprint files maintained by the National Police Agency.

The certificate is not designed as a casual personal background-report service. Prefectural police guidance explains that it is normally issued when a foreign government, embassy, immigration authority, licensing body or other appropriate official authority requires the applicant to submit it for a qualifying purpose.

You normally request your own certificate — not someone else’s

Prefectural police procedures require the person concerned to apply personally because fingerprints must be collected or submitted as part of the process.

Osaka Prefectural Police, for example, explicitly states that a representative cannot submit the original application on the applicant’s behalf because fingerprinting is required.

Residence jurisdiction matters

Applications in Japan are generally handled by the prefectural police headquarters connected to the applicant’s current residence.

A person now living overseas may also be directed based on their last registered address in Japan or may apply through a Japanese diplomatic mission abroad.

Documents usually needed for a Japanese police certificate

Exact document requirements should always be checked with the responsible prefectural police headquarters because procedures can vary slightly.

Official prefectural guidance commonly requires:

A prefectural police headquarters may ask for a Japanese translation when the supporting document is written only in a foreign language.

Fingerprinting is central to the official certificate

The Japanese police certificate is tied to fingerprint records rather than being produced from a simple internet name search.

Applicants should expect fingerprints to be collected as part of the official process. This is also why original applications generally must be made personally rather than through an ordinary representative.

Where to apply while living in Japan

Contact the police headquarters for the prefecture where you are registered as a resident. Do not assume that an ordinary neighborhood police box (koban) or local police station can issue the certificate.

Osaka Prefectural Police, for example, accepts applications only through its prefectural police headquarters and specifically states that applications cannot be submitted at ordinary police stations or police boxes.

How to obtain a Japanese police certificate while living overseas

Japanese citizens and foreign nationals who previously lived in Japan may be able to apply through the Japanese embassy or consulate serving their current location.

Prefectural police guidance advises overseas applicants to contact the Japanese diplomatic mission first because the required documents and processing time can differ from an application submitted inside Japan.

How much does a Japanese criminal-record certificate cost?

Fee rules should be checked with the responsible prefectural police headquarters. Osaka Prefectural Police currently lists its criminal-record certificate application as free of charge.

How long does issuance take?

Osaka’s current official guidance says a certificate is normally issued about two weeks after the completed application, although holidays and unusual cases can extend the processing period.

Do not open the police certificate envelope unless instructed

One particularly important practical detail is that the issued police certificate may be sealed for delivery to the requesting foreign authority.

Osaka Prefectural Police warns that opening the sealed envelope can invalidate the certificate.

The certificate is multilingual

Japan’s police criminal-record certificate is issued in multiple languages.

Current prefectural police guidance states that the certificate is presented in:

The National Police Agency’s standard certificate format itself contains these languages.

If the destination country asks for an apostille or authentication

The police certificate and the legalization of that certificate are separate steps. When the foreign authority requires an apostille or other authentication, follow the Ministry of Foreign Affairs of Japan procedure.

Japan’s Ministry of Foreign Affairs handles apostilles and authentication for qualifying Japanese public documents.

Why court judgment search is not the same as looking up a person’s criminal record

Access to records after a Japanese criminal case is final

Japan does provide a legal route for inspecting certain records from completed criminal proceedings, but this is different from a web-based criminal-history search.

Official NPA victim-support information explains that records and judgments from criminal cases that have become final are kept by the public prosecutors office handling the matter and can be subject to inspection under Japan’s Act on Final Criminal Case Records.

Older Ministry of Justice explanatory material likewise states that final criminal-case records may, in principle, be inspected, subject to the statutory rules and exceptions.

NPA’s current victim-information material notes that records other than the judgment itself are generally subject to a limited inspection period, commonly three years after the judgment becomes final, subject to the applicable law and individual circumstances.

Pending criminal-case records are more restricted

Pending criminal-case files should not be assumed to be available to an unrelated member of the public.

Victims may have specific rights to inspect or copy certain litigation materials during a criminal trial when the legal requirements are met, but this is a special statutory access route rather than a general public background search.

Cases that did not lead to prosecution are not generally open criminal records

Official Ministry of Justice explanatory material states that records of cases in which prosecutors decided not to prosecute are generally not disclosed.

Limited disclosure may sometimes be considered for victims or related parties who need particular evidence to exercise legal rights—for example, in a related civil damages case—but that is not the same as public access for ordinary background research.

You cannot search Japanese arrest warrants on the court website

The Courts of Japan currently publishes an explicit warning that arrest warrants cannot be searched on the official court website.

The court also warns about fake websites impersonating Japanese courts and using supposed warrant information as part of scams.

Can a private employer obtain a Japanese criminal-record certificate?

Japan’s police certificate is not designed as a routine employer background-check product that a private company can order whenever it chooses.

Osaka Prefectural Police expressly states that if a company alone asks an employee to obtain the certificate, the application cannot be accepted unless the certificate is actually required by the relevant foreign official authority or fits another recognized issuance purpose.

For crime trends, use Japan’s official crime statistics instead

If your goal is research into crime rates, offenses or location patterns rather than checking a specific person, the National Police Agency publishes official crime statistics.

NPA currently provides finalized annual statistics going back many years and provisional current-year crime data.

NPA also links to crime open-data portals maintained by Japan’s prefectural police forces. These datasets commonly concern incident locations and offense categories, not personal criminal histories.

Practical tips for researching criminal information in Japan

Official Japanese sources for verifying the process

Editorial note: Criminal-Record.org is an independent informational resource and is not affiliated with Japan’s National Police Agency, prefectural police, Courts of Japan, Ministry of Justice or Ministry of Foreign Affairs. Japan does not provide a general public nationwide name-search system for another person’s complete criminal history. Access depends on the record type, applicant, purpose and applicable Japanese law. Verify visa, immigration, licensing and certificate requirements directly with the official authority that requested the document.
