Depending on the type of a document (private or public) and its purpose of your papers, you might need a different type of verification. This process is also sometimes called attestation, notarisation, or certification. They all mean the same thing: your documents will receive recognition in other institutions or even other countries.

Generally speaking, there are two types of verification: apostille and authentication. In most cases, both lead to legalisation. Notary Publics are usually dealing with private documents, while the Ministry of Foreign Affairs or Embassy/Consulate General with public ones (also called official).

In this guide we will break down four most common types of verification/ legalisation and the process of obtaining them:

  • Authentication (of private documents)
  • Affidavit/sworn authentication (of private documents)
  • Apostille (for public documents)
  • Consular legalisation/authentication (of public documents)

Authentication

What is it?

Authentification means an acquisition of a proof from a Notary Public (or gyosei shoshi) that the document and its description were created using just procedures. Documents containing invalid or illegal matters, documents with the altered, deleted or added text, as well as the documents that may be potentially used to commit a crime cannot be authenticated.

How is it Done?

Such proof means the acknowledgment of the signatures on the document(s). It is done by signing the document(s) or swearing that the signature(s) on the provided document(s) were made by the people who present them themselves in the presence of the Notary Public. Once the signing or certifying the signature is done, the Notary Public will add a note to the document(s) stating the genuineness of the execution. It is possible due to the evidential power of the Notary Public.

Such authorisation is only done to the private documents. Official documents do not require such procedure. However, in some cases, they also need to be legalised. Then it is done at the Legal Affairs Bureau or at the Ministry of Foreign Affairs.

When is it Needed?

In case the document contains the signature and/or a seal on it, it is not always known if this document was prepared by the person who submits it. In such case, gyosei shoshi can authenticate that the person submitting the document has prepared it. These kinds of documents are often needed for use overseas.

Documents Needed for Authentication

When you visit the notary to authenticate your documents, you will have to show one of the following documents to verify your identity:

  • Passport
  • Driver’s License
  • Residents Registration Card (with a full face photograph)
  • Certificate of seal impression and the registered seal (you might have this document if you have registered your seal impression at the city hall or ward office)
  • Alien Registration Card. If the person who is signing is authenticating documents acts as a company’s representative director, they need to provide:
    • the certificate of the seal impression of the representative director
    • the certificate of the company registration

When is the Authentication Ready?

It is ready as soon as you certified the signatures or swore about the content of the documents in front of the Notary Public. Thus, you will get your document ready on the same day of your appointment at the notary’s office.

Affidavit (sworn) Authentication

This type of legalisation is almost identical to regular authentication. The only difference is that Notary Public certifies the content of the document, not the signatures.

This means that the person who submits the document swears that the content of the document is true. These kinds of affidavits are sometimes required by the foreign countries to prove the truthfulness of the documents text. For that reason, stating false information that differs from the real original content of the document is punished by sanctions.

The procedure of acquiring it and the needed documents are the same ones that you need when authenticating your documents (see the previous section).

Apostille

What is it?

Apostille bears the same purpose as the authentication, but it is meant to be presented at the governmental and public institutions.

The word “apostille” is used for the authentification that is valid for all the signatory countries of the Hague Convention of October 5, 1961. Once your documents are verified with the apostle they are officially recognized in all the countries that signed the Hague Convention.

If you need to legalise your documents for the country that did not sign the convention, you will need to obtain consular authentication (see next chapter).

How is it Done?

Your documents will receive an attachment that verifies the document for use in other countries of Hague Convention. In order to get the apostille, you need to apply to the Ministry of Foreign Affairs and provide the set of required documents. You can do that in person, via a representative or by mail. The Ministry will process your request and papers and will attach an apostle.

When is it Needed?

Usually, documents with the apostille are needed for such procedures as marriage, divorce, birth registration, visa application, incorporation or real estate purchase.

Documents Needed for an Apostille

If you are applying for an apostille in person, you will need the following documents:

  • The official document to be certified (original document issued within three months)
  • Application form (also available at the office)
  • Identification Document: driving license, basic resident registration card, passport or residence card, or insurance card

If you apply through the representative, the representative also has to submit a filled-in Power of Attorney.

If you apply via mail, you also need to submit a stamped self-addressed envelope or a letter pack.

Important Notes:

  1. You cannot change the mean of delivery once you have started the process. Applications made in person should be picked up in person from the service desk. Applications through representative are handled by the assigned representative person. Mailed applications are returned by mail.
  2. Mailing is done only within Japan from/to Japanese addresses. You cannot send your pack of documents from overseas, and your documents will not be delivered to you outside of Japan if you leave in the process.
  3. There should be one person responsible for submitting. handling, and picking up the documents. The identity of the applicant will be confirmed at the beginning of the procedure, and only this person will be contacted later on regarding all the application matters.

There is a possibility to order application forms and the Power of Attorney via mail or fax. These can be sent overseas since they are only application forms. You can find more information about these options on the official website of the Ministry of Foreign Affairs. However, the process of legalisation is only possible in Japan.

When is the Apostille Ready?

If you apply in person, your documents will be available the next working day after 9 a.m.

If you ask a representative to obtain an apostille for you, agree on the date of delivery. Since your representative will go to the office in person above-mentionedoned rule apply. Include also the time needed to make a Power of Attorney and to deliver documents to you.

If you apply via mail, you will get your self-addressed letter/pack after 10-14 days. Add the time needed to deliver your documents to the office.

Consular Legalisation/Authentication (of the official seals)

This type of legislation is similar to apostille, but it is used when attaching an apostle is impossible (the country which requested the document has not signed the Hague Convention of 1961). Such authentication can be done either by the Ministry of Foreign Affairs or by the Embassy / Consulate General of Japan. In the case of consular authentication, the handling institution will verify the official seal of the issuing institution.

Please note, that if your documents have been verified by the Ministry of Foreign Affairs, they cannot be verified by the Embassy or Consulate General, and vice versa. Although the legalisation of these institutions has the same power, it is always a good idea to make sure which verification of which institution you need.

The set of documents is the same as for an apostille. The only difference is that you will need the application form for authentication instead of an apostille application.
