There are many cases where a foreign spouse wishes to bring their child from a previous marriage (stepchild) to Japan after an international marriage with a Japanese national. Under certain conditions, such children are permitted to enter Japan on a “Long-Term Resident” (Teijusha) visa.
However, if the stepchild has already reached “adulthood,” the situation changes completely. Under the Immigration Control Act, it is extremely difficult to bring an adult stepchild to Japan solely for the reason of “wanting to live together as a family.” This article thoroughly explains the legal mechanisms of the strict requirements for a Long-Term Resident visa and provides logical alternative approaches for bringing an adult child to Japan.
1. The Absolute Requirement of Being an “Unmarried Minor”
The legal basis for a stepchild of a Japanese spouse to obtain a Long-Term Resident visa is defined in the “Long-Term Resident Public Notice No. 6 (C).” This notice sets a clear condition: the child must be an “unmarried minor biological child” who will “live under the support” of the parent.
What “Necessity of Support” Means to Immigration Authorities
In practical immigration screenings, there are no exceptions to this “unmarried minor” criterion. The core purpose of this visa category is to “protect children who cannot live independently without their parents’ protection.”
Children who are already adults, or who are married and independent, are legally deemed to have the “ability to make an independent living.” Consequently, the necessity for them to live under their parents’ support is denied. Therefore, the mere fact of their parent’s marriage does not make them eligible for a Long-Term Resident visa.
2. The Harsh Reality of the Civil Code Revision: Adulthood at 18
In practice, the most critical point to note is that the legal age of adulthood in Japan was lowered to “18 years old” following the revision of the Civil Code in April 2022. This revision directly impacts the screening criteria under the Immigration Control Act, meaning that currently, “anyone aged 18 or older is strictly treated as an adult.”
The 18th Birthday is the Time Limit
Previously, it was possible to apply as a minor if the child was under 20. Now, the moment the child turns 18, they are judged as being of an “age capable of living independently.” Furthermore, immigration authorities focus not only on the age “at the time of application” but also “at the time of the decision (approval).” Even if an application for a Certificate of Eligibility is submitted when the child is 17 years and 11 months old, if they turn 18 during the screening period, they will be judged as lacking the minor requirement, drastically increasing the risk of denial.
Additionally, even if the age requirement is met, in cases where the child has graduated from high school in their home country and is already working, they will be deemed “economically independent (no need for support),” making it extremely difficult to obtain approval.
3. Realistic Alternative Approaches for Adult Children
Since bringing them over as a dependent family member (Long-Term Resident visa) is legally impossible, an adult child must obtain an independent status of residence based on the “activities they will perform in Japan.”
Alternative 1: Entry via a “Student” Visa
The most realistic approach, which also leads to future career development in Japan, is the “Student” visa. The child comes to Japan to enroll in a Japanese language school, vocational school, or university.
- Advantages: The hurdles regarding educational or professional background are low. If the parent in Japan becomes the “financial sponsor” (paying tuition and living expenses), proving financial capability becomes straightforward.
- Important Notes: Because the primary purpose is “study,” school attendance rates are strictly monitored. After graduation, the goal will be to change to a work visa, as described below.
Alternative 2: Entry via a “Work Visa” (Engineer/Specialist in Humanities/International Services)
If the child has graduated from a university (including junior colleges) in their home country, they can independently obtain a work visa, such as “Engineer/Specialist in Humanities/International Services,” by securing a job offer from a Japanese company.
- Advantages: They arrive in Japan as working adults rather than students, allowing them to build a stable life without time constraints (such as the 28-hour per week limit on part-time work for students).
- Important Notes: There must be a clear correlation between their university major and their job duties at the Japanese company. Unskilled manual labor is not permitted.
Alternative 3: Entry via a “Specified Skilled Worker” Visa
If the child has only a high school diploma and has not graduated from university, the “Specified Skilled Worker” (Tokutei Ginou) visa is a strong option. By passing the skills test for designated industries (e.g., food and beverage manufacturing, nursing care, restaurant industry) and a Japanese language test (N4 or higher), they can work in Japan.
- Advantages: There are no educational requirements. As long as they pass the tests and find a host company, they can come to Japan.
- Important Notes: For Specified Skilled Worker (i) visas, bringing family members is generally not allowed, which may impose certain restrictions on future life plans.
4. Frequently Asked Questions (Q&A: Adult Stepchildren)
- Q: My child is 18, still in high school in their home country, and not economically independent. Is a Long-Term Resident visa possible?
A: It must be said that this is extremely difficult. In practice, the legal wall that “18 and over is an adult” takes precedence. In this case, the most reliable route is to have them graduate high school in their home country, then enter a Japanese language school in Japan using a “Student” visa. - Q: My adult child has a severe illness in their home country and needs my care. Can they be brought over as an exception?
A: This would not be a Long-Term Resident visa, but an application seeking humanitarian consideration under the “Designated Activities” (outside public notice) visa. However, this requires proving exceptionally high hurdles, such as the complete absence of any other relatives in the home country to provide care, and having sufficient financial resources to pay for expensive medical treatments in Japan. - Q: Can I bring them over on a “Temporary Visitor” (Tourist) visa first and change it in Japan?
A: In principle, this is not possible. Changing from a Temporary Visitor visa to a long-term visa is not permitted unless there are “special unavoidable circumstances” (Immigration Control Act, Article 20, Paragraph 3). They must return to their home country and undergo the proper procedure to apply for a Certificate of Eligibility.
Bringing adult family members to Japan is subject to strict screenings based on the principles of the Immigration Control Act. Forcing an application simply because “we are family” can result in leaving a record of denial. It is necessary to organize the factual background—such as educational history, professional background, and age—and construct a logical and solid approach to the appropriate visa status.
