Japan Long-Term Resident Visa for Grandchildren of Japanese Nationals: Nikkei Sansei and Descendants of Former Japanese Nationals

Can a grandchild of a Japanese national live in Japan?

In certain cases, yes.

A foreign national who is the grandchild of a Japanese national or former Japanese national may qualify for Japan’s Long-Term Resident visa (定住者 / Teijusha) as a third-generation Japanese descendant, commonly referred to as Nikkei Sansei (日系三世).

This category can be particularly important for people whose Japanese parent or grandparent emigrated overseas, acquired another nationality, or lost Japanese nationality many years ago.

Eligibility, however, depends heavily on the precise family history — including when each family member was born and when Japanese nationality was lost.

For this reason, establishing the applicant’s Japanese ancestry through Japanese family registers (koseki) and foreign birth, marriage, and nationality records is often the central issue in these applications.

At Continental Immigration Law Firm, we assist clients in English throughout the entire process, including investigation of Japanese family records and, where legally available, obtaining relevant family-register documents in Japan through procedures available to licensed Gyoseishoshi.

What Is the “Long-Term Resident” Status in Japan?

The Long-Term Resident status of residence, known in Japanese as Teijusha (定住者), is a status granted to certain foreign nationals whose personal or family circumstances justify residence in Japan.

Unlike a standard work visa, eligibility is generally based on the applicant’s status, family background, or other special circumstances, rather than simply on a particular job.

One important category covers certain descendants of Japanese nationals.

The Immigration Services Agency of Japan specifically provides application procedures for third-generation Japanese descendants (Nikkei Sansei) under the Long-Term Resident status.

For many applicants of Japanese descent, the critical question is therefore not simply:

“Was my grandparent Japanese?”

The more important questions are:

• Was the grandparent Japanese when the applicant’s parent was born?
• Did the Japanese ancestor later acquire another nationality?
• When did the ancestor lose Japanese nationality?
• Was the applicant’s parent born before or after that loss of nationality?
• Can the family relationship be established through Japanese and foreign official records?

These facts can determine which legal category applies.

Long-Term Resident Notification No. 3: Third-Generation Japanese Descendants

One of the principal routes is Long-Term Resident Notification No. 3.

In simplified terms, this category covers certain persons who are the biological descendants of a person born as the child of a Japanese national and who are of good conduct.

This is the category most commonly associated with Nikkei Sansei — third-generation Japanese descendants.

Typical example

A common family structure would be:

Japanese grandparent
↓
Second-generation child
↓
Applicant: third-generation descendant (Nikkei Sansei)

In other words, if your grandfather or grandmother was Japanese, there may be a possibility that you qualify for Long-Term Resident status.

However, Japanese nationality law and the timing of births and nationality changes must also be examined.

Former Japanese Nationals May Also Be Relevant

The analysis becomes more complicated where the Japanese ancestor later lost Japanese nationality.

For example:

• a Japanese national emigrated overseas;
• the person subsequently acquired foreign nationality;
• Japanese nationality was lost;
• children or grandchildren were born before or after that loss of nationality.

Depending on the chronology, the grandchild may still fall within one of the Long-Term Resident categories.

This is why a simple copy of a grandparent’s old Japanese passport or a statement that “my grandmother was Japanese” is often not sufficient.

The immigration authorities may need to understand the complete legal family history.

Long-Term Resident Notification No. 4: Grandchildren of Certain Former Japanese Nationals

Long-Term Resident Notification No. 4 provides another route for certain third-generation descendants.

This provision concerns the grandchild of a person who:

1. was born as the child of a Japanese national;
2. was previously a Japanese national; and
3. had a registered domicile (honseki) in Japan.

This category is particularly important because it can cover certain family histories involving the loss of Japanese nationality that may not fit neatly within Notification No. 3.

For example, it may become relevant where a former Japanese national lost Japanese nationality and the subsequent generations were born after that change in nationality.

The distinction between Notification No. 3 and Notification No. 4 can be highly technical.

In practice, the issue must often be reconstructed from documents showing:

birth → Japanese nationality → foreign nationality acquisition → loss of Japanese nationality → birth of the next generation → birth of the applicant

The exact sequence can determine the appropriate immigration route.

Example: Grandchild of a Japanese National

Consider the following example:

Grandmother: Born in Japan as a Japanese national
Mother: Born overseas
Applicant: Born overseas and currently holds a foreign nationality

The applicant may potentially qualify as a third-generation Japanese descendant.

However, before determining eligibility, it is necessary to confirm matters such as:

• whether the grandmother was still Japanese when the mother was born;
• whether the grandmother later acquired another nationality;
• whether Japanese nationality was lost automatically or through another procedure;
• whether the mother’s birth was recorded in a Japanese family register;
• whether the mother ever possessed Japanese nationality; and
• whether the documentary chain from the Japanese ancestor to the applicant can be established.

The result may differ depending on these facts.

Example: Grandchild of a Former Japanese National

A different analysis may apply where the Japanese ancestor had already lost Japanese nationality before the next generation was born.

For example:

Japanese national
↓
acquires foreign nationality and loses Japanese nationality
↓
child born after loss of Japanese nationality
↓
grandchild

In this type of case, Notification No. 4 may become particularly relevant.

Accordingly, applicants should not assume that they are ineligible merely because their parent or grandparent was no longer Japanese at the time of a later birth.

A detailed review of the family history is necessary.

Good Conduct Is Also Required

Japanese ancestry alone does not automatically guarantee approval.

The Long-Term Resident notification applicable to Nikkei descendants includes a good-conduct requirement.

Accordingly, immigration authorities may consider matters such as the applicant’s criminal record and overall background when examining the application.

The appropriate supporting documents will depend on the applicant’s nationality, country of residence, family circumstances, and application history.

The Most Important Evidence: Japanese Family Registers

For many Nikkei Sansei cases, one of the most difficult parts of the application is not completing the immigration forms.

It is proving the Japanese family line.

Japan’s family registration system — the koseki (戸籍) — can contain critical information concerning:

• births;
• parents and children;
• marriages;
• registered domicile;
• nationality-related events; and
• historical family relationships.

Old family registers may therefore provide the documentary foundation connecting the applicant with a Japanese or former Japanese ancestor.

In some cases, several generations of records must be traced.

What If I Do Not Have My Grandparent’s Koseki?

This is a common situation.

Many descendants of Japanese emigrants living in the United States, Canada, Brazil, Peru, Australia, Europe, and other countries do not possess their grandparents’ Japanese family records.

Some applicants know only:

• the ancestor’s Japanese name;
• approximate date of birth;
• prefecture or town of origin;
• name of a parent;
• approximate year of emigration; or
• an old Japanese passport or other historical document.

That does not necessarily mean that the case cannot proceed.

Where legally available and necessary for the immigration matter, Continental can investigate Japanese family records and obtain relevant koseki documents in Japan through professional procedures available to licensed Gyoseishoshi.

We then compare the Japanese records with foreign birth certificates, marriage certificates, nationality records, and other civil-status documents to establish the family relationship.

Why Nationality History Matters

One of the most frequently overlooked issues in Japanese-descendant cases is the date on which an ancestor lost Japanese nationality.

For immigration purposes, these two situations can produce different legal analyses:

Scenario A

Japanese national
→ child is born
→ Japanese parent later loses Japanese nationality

and:

Scenario B

Japanese national
→ loses Japanese nationality
→ child is subsequently born

They may appear almost identical from a family-history perspective.

Legally, however, the difference can be significant.

This is particularly important when determining whether a case falls within Long-Term Resident Notification No. 3 or No. 4.

Documents Commonly Required

The precise document list varies depending on the case, but a Nikkei Sansei application may require documents such as:

• Japanese family registers (koseki tohon and historical family registers);
• the applicant’s birth certificate;
• birth certificates of the applicant’s parent;
• marriage certificates;
• documents concerning the Japanese ancestor;
• documents showing acquisition or loss of nationality;
• passport copies;
• documents concerning the applicant’s family circumstances;
• police or criminal-record documentation where applicable;
• financial or employment information;
• a guarantor document; and
• an immigration questionnaire and application forms.

The Immigration Services Agency may request additional evidence depending on the individual case.

For applicants outside Japan, the procedure will generally begin with an application for a Certificate of Eligibility (COE) where applicable.

Can I Apply If I Do Not Have a Sponsor in Japan?

Potential options may still exist even when the applicant does not currently have close family members in Japan.

The appropriate application structure will depend on the applicant’s circumstances, available family records, residence situation, and the particular Long-Term Resident category.

Applicants should therefore have their family history reviewed before concluding that the absence of a Japanese relative or sponsor makes an application impossible.

Can a Grandchild of a Former Japanese Citizen Obtain a Japan Visa?

Potentially, yes.

A person may qualify even where the Japanese ancestor later became a foreign national.

The critical issue is not merely the ancestor’s nationality today.

Instead, the analysis focuses on matters such as:

• whether the ancestor was originally Japanese;
• the ancestor’s Japanese family registration;
• when Japanese nationality was lost;
• when each subsequent generation was born; and
• whether the required biological family relationships can be proven.

For descendants of former Japanese nationals, this chronological analysis is particularly important.

Is Nikkei Sansei the Same as “Spouse or Child of Japanese National”?

No.

The status of residence “Spouse or Child of Japanese National” (日本人の配偶者等) can cover, among others, a person born as the biological child of a Japanese national.

By contrast, a grandchild of a Japanese national will generally need to consider a different legal basis, including the Long-Term Resident provisions applicable to Nikkei descendants.

The correct status therefore depends on the precise relationship between the applicant and the Japanese ancestor.

Frequently Asked Questions

My grandmother was Japanese. Can I get a visa to live in Japan?

Possibly. A grandchild of a Japanese national may qualify for Long-Term Resident status as a third-generation Japanese descendant. Eligibility depends on the family history, nationality history, and supporting documentation.

My grandfather gave up Japanese nationality. Am I still eligible?

Possibly. Loss of Japanese nationality by an ancestor does not automatically eliminate eligibility. The timing of the loss of nationality and the births of subsequent generations must be examined.

My parent was never a Japanese citizen. Can I still qualify?

Potentially, yes. Some Long-Term Resident categories are specifically designed to cover descendants whose family history includes former Japanese nationals. The precise genealogy and nationality chronology must be reviewed.

I do not have my Japanese grandparent’s koseki. What should I do?

It may still be possible to locate the relevant Japanese family records. Information such as the ancestor’s Japanese name, date of birth, place of origin, parents’ names, old passport information, or historical records can be helpful.

Can Continental obtain Japanese family-register documents for me?

Where legally available and necessary for the immigration matter, we can assist in obtaining relevant Japanese family-register records through professional procedures available to licensed Gyoseishoshi.

Is speaking Japanese required for a Nikkei Sansei Long-Term Resident visa?

Japanese ancestry and the applicable Long-Term Resident requirements are the primary legal issues. However, the documentation and requirements applicable to the particular application, including the requested period of stay, should be reviewed individually.

Can I work in Japan with Long-Term Resident status?

Long-Term Resident is a status based on personal status rather than a specific occupational category. It generally provides substantially broader employment flexibility than work statuses tied to particular professional activities.

Determining Eligibility Starts With Your Family Tree

For descendants of Japanese nationals, the first step is usually not filing an immigration application.

It is determining exactly what happened in each generation.

A seemingly small difference — such as whether a grandparent lost Japanese nationality before or after the birth of a child — can change the applicable legal category.

If your grandfather or grandmother was Japanese, or if you are the grandchild of a former Japanese national, you may have a potential route to Long-Term Resident status in Japan.

Continental Immigration Law Firm can review your family history, investigate available Japanese records, and determine the appropriate immigration strategy.

English-language consultations are available for clients residing both inside and outside Japan.
