The short answer, which is the answer most people need and do not get early enough:
No on SSW (i). Yes on SSW (ii).
Verify before you act on this. The Specified Skilled Worker system is revised frequently. The Immigration Services Agency of Japan and the ministry responsible for your field are the sources that bind. This page is orientation, not authority.
SSW (i): family cannot accompany you
The status nearly everyone enters on — 特定技能1号 — does not permit dependants. Your spouse and children stay in your home country for the duration.
Combined with the five-year cap on Type 1, that shapes the whole experience. Five years is long. It is long enough for children to grow up without you there, and that cost is routinely underweighted by candidates focused on the wage.
Be clear-eyed about it before you commit.
SSW (ii): family may join you
特定技能2号 permits your spouse and minor children to come to Japan as dependants. It also removes the five-year cap and counts towards permanent residency.
This is why Type 2 is not a technicality. For anyone with a family, it is the entire point of the route.
How you get there
Type 2 is not granted by waiting. You qualify:
- Accumulate the required practical experience in your field, typically including work at a skilled or supervisory level.
- Pass the higher-level skills evaluation test for your field.
- Apply to change status.
No additional language test is formally required. In practice the higher skills test is in Japanese and the roles involved need far more than A2, so the workers who reach Type 2 are the ones who kept studying after arriving. See SSW (i) versus (ii).
Nursing care is different
There is no SSW (ii) in nursing care.
Care workers instead move to the separate 介護 (Caregiver) status of residence by passing the national Certified Care Worker qualification. That status has no maximum period of stay and does permit family accompaniment — the same destination, reached through a professional qualification.
What this should change about your plan
Choose a field with a Type 2 route — or care, which has its own. A field without one is a five-year separation with no way to extend it.
Aim at Type 2 from the start. Five years sounds like plenty and is not: you need experience, a harder test in Japanese, and an application. Workers who begin thinking about it in year four are generally too late.
Keep studying. This is the practical bottleneck. Reaching Type 2 is a language project as much as a skills one, whatever the formal requirements say.
What to prepare for if family do join you
Worth thinking about in advance rather than on arrival:
- Schooling. Japanese public schools will generally accept foreign children; instruction is in Japanese, and support for non-Japanese-speaking children varies considerably by municipality.
- Your spouse’s work. Dependants’ ability to work is restricted and requires permission. Do not assume a second full income.
- Housing and cost of living, which change substantially with a family.
- Their Japanese. The adjustment is harder for a spouse with no language than for the worker, who at least has a workplace and a routine.
Where this starts
With the language requirement, which gates everything and takes the longest. JFT-Basic runs roughly monthly and is usually the fastest instrument — our free practice test reports by section in about fifteen minutes.
Then keep going past it. That is the part that decides whether five years becomes a life.
