Who Can Instruct Japan-Side Document Work? Client Identity, Authority, and Third-Party Requests

“Our client needs a Japanese family register, apostilled and translated. The client’s mother in Osaka will send you the details.”

The message names a document, a task, and three parties. It does not say whose register is required, whether the Japan-side engagement is with the firm or with its client, what role the mother holds, or whether anyone involved has a basis to request that register in Japan.

The person sending an instruction is not necessarily the client. The client is not necessarily the person whose record is required. And neither fact, by itself, establishes authority to obtain or process that record in Japan.

For overseas counsel, immigration and global mobility professionals, corporate legal and compliance teams, and other professionals who instruct Japan-side document work, this article separates the parties to a matter from the authority to act for them, and explains why that authority is assessed for each requested act rather than once for the matter as a whole.

1. One Matter Can Involve Several Different People

In the simplest matter, one person requests their own record, pays for it, and receives it. In cross-border matters, the roles below are often split across several people and organizations.

Two of these distinctions cause most of the confusion in practice.

The payer is not automatically the client. A parent may pay for an adult child’s documents, an employer for an employee’s, and a law firm may advance costs for its own client.

The contact person is not automatically authorized to act for the record subject. A relocation coordinator or a family member who manages the correspondence may know every relevant fact without holding any authority to request the record.

2. Instruction and Authority Are Different Questions

A matter in which overseas counsel, an immigration professional, or a corporate mobility team instructs the Japan side on someone else’s behalf is an ordinary and workable structure for cross-border document work.

In that structure, three positions are usually distinct:

• the overseas professional may be the instructing professional;
• the underlying individual or entity may be the client or principal; and
• authority to obtain a particular Japanese record must still be assessed under the rules applicable to that record.

An instruction establishes who is asking. It does not establish that the requested Japan-side act is authorized.

Our earlier Insight, Instructing Japan-Side Document Work: What Overseas Professionals Should Provide Before Work Begins, sets out what information makes an instruction executable. This article addresses the question beneath it: who is acting, for whom, and whether the requested Japan-side act is authorized.

3. Authority Is Record-Specific and Procedure-Specific

Authority is often treated as a single attribute of a matter. Japanese procedures do not work that way: the question attaches to the requested act, such as:

• obtaining a particular record;
• instructing authentication;
• instructing translation;
• receiving completed originals; and
• giving procedural instructions on the matter.

For procurement, official guidance at the time of writing shows how far the rules differ from one record to the next.

Family-register certificates. Under the Ministry of Justice’s guidance, a family-register certificate can be requested by the person recorded in the register or by that person’s spouse, lineal ascendants, or lineal descendants. A third party can request it only on specified grounds — to exercise their own rights or perform their own obligations, to submit it to a national or local government body, or for another legitimate reason — and the request must state those grounds specifically. A representative submits a power of attorney prepared by the person entitled to make the request.

Within the same record, the route matters. Since March 1, 2024, the person recorded in the register, a spouse, and lineal relatives can request family-register certificates at a municipal office other than the one holding the register (wide-area issuance), but the Ministry of Justice states that requests by mail or through a representative are not accepted for that service. A power of attorney may be relevant to one procurement route without making every other route available.

Certificates of entries in notification records. The notification forms filed for births, marriages, and other family-register events are retained after the register is updated and are, in principle, not public. Under Article 48(2) of the Family Register Act, as the Tokyo Legal Affairs Bureau’s guidance explains, a certificate of their entries can be requested only by an interested person — such as the subject of the notification, the person who filed it, or a relative — and only where a special reason exists: broadly, where a right cannot be exercised without information that appears in the notification records but not in the family register.

A representative can make that request with a power of attorney, but the required documents still include evidence of the interested-person status and of the special reason. The same guidance states that even lawyers and judicial scriveners cannot use the professional request procedure for these certificates and require separate authorization.

Corporate registry certificates. The Legal Affairs Bureau’s commercial registration FAQ states that anyone can obtain a company’s certificate of registered matters by paying the prescribed fee. The same FAQ states that a company’s seal certificate can be requested only by the company’s representative, although the request can be made through a proxy. Two certificates issued by the same registry offices follow two different access rules.

Authentication. The Ministry of Foreign Affairs (MOFA) applies its own authorization rules to apostille and other certification applications made by a proxy, separately from the rules under which the record was obtained.

“Authority to obtain a document” cannot be answered by one universal rule. It is answered for a specific record, through a specific procedure, under the rules that govern that procedure — and the current rules should be confirmed with the issuing authority for each request.

Authority is also a different question from selection. A person entitled to request a family register may still be requesting the wrong record for the receiving side’s purpose; choosing the record is examined in our earlier Insight, Choosing the Right Japanese Record Before Authentication: A Framework for Overseas Counsel.

4. A Power of Attorney Is Not a Universal Access Pass

A power of attorney shows that a particular person has authorized a particular representative. It leaves other questions open:

• Existence. Is there a written authorization, and is it in final form?
• Grantor. Who signed it?
• Grantor’s standing. Is that person able to authorize the requested act — for a procurement request, someone whom the rules for that record allow to make the request?
• Scope. Which record, which procedure, and which act does it cover?
• Issuing-authority requirements. Does the authorization meet the requirements of the Japanese authority that handles that procedure?

Under the family-register guidance above, for example, the power of attorney comes from a person who could make the request in their own right; an authorization from anyone else is not the document the procedure calls for.

Whether a power of attorney is required, permitted, insufficient on its own, or irrelevant depends on the procedure. For a company’s certificate of registered matters, it is not the basis of access at all. For certificates of entries in notification records, it is permitted but insufficient on its own. For wide-area issuance of family-register certificates, it is of no use, because that route is not open to representatives.

5. Overseas Counsel Can Instruct the Work Without Becoming the Record Subject

A typical business-to-business matter involves four positions:

Underlying client / principal
↓ represented by
Overseas counsel
↓ instructs
Japan-side provider
↓ where procurement is requested
Japanese issuing authority

Counsel acts for the underlying client and instructs the Japan-side provider; the provider makes any request to the Japanese issuing authority, which applies its own rules to that request.

Sending the instruction does not make counsel the record subject, and professional standing abroad is not, by itself, a basis for requesting a Japanese record; that basis is assessed under the Japanese rules for the record.

What the Japan-side provider needs to know is structural:

• who the overseas professional represents;
• whose Japanese record is required;
• what Japan-side act is requested; and
• where procurement is requested, what authority or access basis is relied upon.

The Japan side does not assess an overseas professional’s authority under foreign law or professional rules. It needs the structure of the matter stated clearly enough to put the Japanese access question to the right person.

6. Family Members and Other Third Parties

Inquiries also come from people close to the record subject: a parent, an adult child, a spouse, a sibling, a friend, or a colleague in a company’s HR team.

Family relationship, practical involvement, or possession of information does not automatically answer the authority question.

Relationship can matter. Under the family-register guidance, a spouse and lineal relatives can request the register, and the relationship may need to be documented. A sibling is not in that group and would need another recognized ground — the guidance gives the example of a sibling who has become the heir of a deceased brother or sister. For other records, the relationship may be irrelevant.

The same applies inside organizations. Under MOFA’s current guidance, a company employee can apply, without a separate authorization, for certification of a public document that names the company, such as the company’s registry certificate, but a proxy application for an employee’s personal certificate, such as a family-register certificate or diploma, requires the employee’s authorization. An HR team’s role in a relocation does not extend automatically to every record of the employee.

The rule, therefore, is not that family members or colleagues can or cannot act. It is that the relationship is assessed against the rules for the specific record and procedure.

7. Intermediaries Create an Additional Identification Layer

Study-abroad agencies, relocation companies, consultants, and coordinators often sit between the record subject and the Japan-side provider. Their involvement is ordinary and frequently useful. It also adds a layer in which the basic answers can become harder to see:

• Who is the actual client?
• Who is the underlying principal?
• Whose document is being processed?
• Who authorized the Japan-side work?
• To whom may originals and personal information be returned?

When those answers are blurred, the consequences are concrete: a record requested without a confirmed basis, or originals and personal information released to someone the record subject never authorized to receive them.

In our practice, where the principal, the client, or the authority for the requested act is unclear, we ask for additional confirmation before work begins, and we may decline a matter in which the necessary confirmation cannot be obtained. That is an operating policy of this office, not a statement that requests made through intermediaries are restricted under Japanese law.

8. Payment Does Not Determine Client Identity

In international matters, the party paying for Japan-side work is often not the party whose record is needed.

Payment settles who bears the cost. It does not settle who the client is, whose record is involved, or who can authorize the requested act.

The billing party is confirmed as a separate item, alongside — not in place of — the client, the record subject, and the source of authority.

9. Delivery Instructions Also Require Role Clarity

Completed originals, apostilles, and Certified Translations have to go somewhere, and the destination is its own instruction. The client, the record subject, instructing counsel, the payer, and the final recipient may all be different.

Because the package contains original public documents and personal information, the destination is not set automatically by whoever made the first contact; it is confirmed against the roles identified in the matter.

Issuing authorities can impose their own constraints at the procurement stage. The Tokyo Legal Affairs Bureau’s guidance on postal requests for certificates of entries in notification records, for example, limits the return address to the current address shown on the identity document of the requester or the representative.

The final review of the completed package before it is transmitted abroad is a separate step, discussed in our earlier Insight, Before Filing Abroad: A Final Review Framework for Japanese Documents, Apostilles, and Translations.

10. A Practical Party-and-Authority Checklist

1. Client — Who is the client?
2. Instructing party — Who is sending the instruction, and on whose behalf?
3. Record subject — Which person or entity is the subject of the Japanese record?
4. Authority for procurement — If procurement is requested, who has the right or authority to request that specific record?
5. Role of a power of attorney — For that particular procedure, is a power of attorney required, permitted, insufficient on its own, or irrelevant?
6. Operational contact — Who handles day-to-day communication?
7. Payer — Who is paying?
8. Recipient — Who should receive the completed originals and translations?
9. Split roles — Are any of these roles held by different people or organizations?
10. Route confirmation — Has the Japan-side provider confirmed the procurement route before originals or sensitive information are sent?

Item 5 is a procedure-specific assessment, made against the rules for the record and the route actually used — not a legal conclusion reached once for every matter.

The checklist identifies who is involved and on what basis; it does not by itself establish that procurement is possible in a particular case or that the matter can be accepted.

11. The Japan-Side Representative’s Role

Depending on the agreed scope, a Japan-side representative may:

• identify the relevant Japanese record;
• confirm the issuing authority and the available form;
• assess the applicable Japan-side procurement route;
• identify required authorization documents, where applicable;
• procure records where legally and practically permissible;
• arrange authentication, including a MOFA apostille where required;
• prepare Certified Translation; and
• assemble and dispatch the agreed package.

The boundaries are equally specific. The representative:

• does not decide foreign legal sufficiency;
• does not guarantee that the receiving authority will accept the document;
• does not treat an intermediary’s instruction as proof of authority; and
• does not assume that a power of attorney creates access to every Japanese record.

Confirm who is acting and on what basis; the judgment about foreign sufficiency stays with the receiving side.

12. Conclusion

Most Japan-side matters are described by the document they need. The order of work is better set by the people behind that document and the authority they hold:

Parties
→ Authority for the requested act
→ Japanese record
→ Procurement route
→ Authentication / translation
→ Final recipient

This leads to the operational rule of this article:

Identify the parties first. Determine authority for the specific Japan-side act second. Build the document workflow third.

Each step depends on the one before it: a record should not be requested on a basis no one has confirmed, and a package should not be released to a recipient no one has identified. Whether the finished documents meet the receiving side’s requirements remains a decision for the receiving authority.

Clear instructions identify not only what should be done, but also who is asking, for whom, and on what authority.

Scope Note

Apostille Japan is a Tokyo-based Gyoseishoshi office handling agreed Japan-side steps for eligible documents issued or prepared in Japan, including document review and procurement where legally and practically permissible, notary coordination where required, Ministry of Foreign Affairs apostille applications, Certified Translation, final document checks, and international delivery for submissions to the United States, the United Kingdom, Singapore, New Zealand, and the Philippines.

The required evidence, document form, authentication route, translation requirement, and final submission structure depend on the receiving authority, document type, issuing authority, and purpose of use. Apostille Japan does not determine foreign-law requirements or guarantee acceptance by a receiving authority.

This article concerns the identification of the parties to a Japan-side document matter and the authority for the Japan-side acts requested in it. It does not address fees, turnaround, or engagement terms, does not provide advice on the law of any foreign jurisdiction or on an overseas professional’s authority under that law, and does not determine whether a particular request can be made or a particular matter can be accepted. The Japanese access rules described in this article reflect official guidance at the time of writing.
