SSW Type 1 vs Type 2: The Conversion Path Explained

The Specified Skilled Worker visa splits into two tiers, and the gap between them is the single most important strategic decision in the whole programme. The pillar overview explains what the two tiers are; this article goes one layer deeper into how you actually move from Type 1 to Type 2 — the conditions, the exam, the process, which fields can make the jump, and exactly what changes for your family and your stay the day you convert.

This matters because Type 1 (特定技能1号) is designed as a time-limited working stint — capped at five years in total, with no family. Type 2 (特定技能2号) is the tier that turns SSW from a temporary job into a long-term life: no total cap, family allowed, and years that count toward permanent residency. Until 2023 Type 2 existed in only two fields; the reforms since have opened it across most of the list, which is why planning the conversion now makes sense for far more workers than before.

1. The move that defines your SSW future

Almost no one arrives on Type 2. The realistic shape of an SSW career is: enter at Type 1 (the four gates — qualifying sector, skills test, language test, job offer), work, build skill and a track record, then convert to Type 2 before the five-year Type 1 clock runs out. The pillar comparison table lays out the end states; what it does not cover is the mechanics of the crossing, which is where most of the planning, the risk, and the payoff actually sit.

Three things make the conversion the centrepiece of any serious SSW plan. First, the five-year Type 1 cap is cumulative (通算, "total"), not continuous — every day on Type 1 counts against the same five-year budget, so time lost early cannot be made up later. Second, the benefits that change on conversion are large and concrete: an open-ended stay, the right to bring a spouse and children, and years that finally count toward permanent residency. Third, not every field can convert — so your sector choice on day one silently determines whether Type 2 is even available to you.

2. What changes the day you convert

The pillar's table summarises the headline differences; here is what each one means in practice once you hold Type 2 status.

The five-year cap disappears — and the renewal works differently. On Type 1, your total stay across all renewals is capped at five years. On Type 2 there is no upper limit on total stay; you renew indefinitely. Each Type 2 grant is issued as a period of up to three years (commonly described by the sector bodies as a maximum of three years per grant, with no limit on the number of renewals), so the practical rhythm becomes a three-yearly renewal rather than Type 1's shorter annual blocks. The total, though, is uncapped — which is what makes long-term settlement possible.

Your family can finally join you. Type 1 does not normally allow dependents. Type 2 does: a spouse and children can come to Japan under the 家族滞在 (Dependent) status of residence. This is not automatic — the standard dependent checks still apply, meaning you must show you can financially support them and have suitable housing — but the eligibility that Type 1 denies is exactly what Type 2 grants. For many workers this single change is the reason to chase Type 2 at all.

Your years start counting toward permanent residency. Permanent residency requires around ten years of residence, of which at least five must be on a working status. The critical detail is that Type 1 years do not count toward that five-year working portion; Type 2 years do. So the clock on the PR requirement effectively starts when you convert, not when you first arrive.

3. Which fields actually offer Type 2

Type 2 is now available across most — but not all — of the 16 SSW fields. The expansion happened in stages: Type 2 originally existed in only two fields (construction and shipbuilding), and a June 2023 cabinet decision opened it across the majority of sectors. Fields that currently offer Type 2 include the major ones where long-term, seasoned workers are needed:

• Construction (建設)
• Shipbuilding and ship machinery (造船・船用工業)
• Building cleaning
• Industrial product manufacturing
• Agriculture (農業)
• Fishery (漁業)
• Food and beverage manufacturing
• Accommodation (宿泊)
• Food service / restaurants (外食業)

Two important exclusions remain. Nursing care (介護) does not have a Type 2 track — its long-term route runs through a different status entirely (see §8). And the four fields added in March 2024 — automobile transportation, railways, forestry, and the timber industry — are Type 1 only for now; their Type 2 rules have not been opened at the time of writing. Because the field list evolves with each cabinet decision, treat the official SSW field directory as the authoritative current source rather than any fixed list, including this one.

4. The conversion bar: supervisory skill, not just time

Type 2 is not a reward for having simply survived five years on Type 1. It demands a higher, supervisory level of skill (熟練) — the competence of someone who can lead, train, and take responsibility on a worksite, not just perform the core tasks. The pillar table records this as "supervisory-level skill"; in practice it is verified by a separate, harder exam for your sector, distinct from the Type 1 skills test.

One detail that surprises people: Type 2 has no Japanese-language test. Where Type 1 requires the JFT-Basic (A2) or JLPT N4, Type 2 drops the language requirement entirely — the official comparison lists a language level only for Type 1. The entire gate for Type 2 is the supervisory skills exam plus, in most cases, a demonstrated track record. (You will of course need functional Japanese to actually do a supervisory job, but there is no separate certificate to sit.)

5. The field exams and experience requirements

Each sector runs its own Type 2 exam through the same industry body that handles its Type 1 test. The manufacturing field, administered by JAIM (the Japan Association for Human Resources in Industrial Product Manufacturing), is the best-documented example and shows the shape of the requirement clearly. To convert into Type 2 manufacturing you generally need to pass the SSW(ii) manufacturing exam and hold either a Business Career Test Level 3 certificate (ビジネスキャリア試験3級) or a Level 1 national skills certificate (技能1級), alongside roughly three or more years of relevant experience at a company with operations in Japan. Construction, similarly, routes through JAC, which sets its own supervisory-level scope.

The pattern across fields is consistent even when the details differ: a sector-specific supervisory skills exam plus a track record of real experience. The exact years of experience and the precise ancillary certificates vary by field, and the sector bodies update these over time, so the safe approach is to read your field's official Type 2 page (for example, construction or manufacturing) and treat it as the authority. Do not rely on a single generic number — the manufacturing "three years" is a real, cited example, but it is not a universal rule.

6. The conversion process step by step

The mechanics of converting resemble other in-Japan status changes, but the preparation is what takes the effort:

1. Build your Type 1 track record. Work in your sector, accumulate the experience your field's Type 2 page asks for, and develop toward supervisory responsibility. This is the longest phase and it runs against the five-year Type 1 clock.
2. Sit and pass the SSW(ii) exam for your field (plus any ancillary certificate the field requires, such as the Business Career Test). The exam is the core gate — it is what proves you have moved beyond entry-level competence.
3. Have your employer file a change of status application. Conversion from Type 1 to Type 2 is a change of status of residence filed with the Immigration Services Agency, usually supported by your employer and evidence of your passed exam and experience. The fee structure is the same as other status changes — around 6,000 yen in person or 5,500 yen online since the April 2025 revision.
4. On approval, your conditions change immediately. Your new period of stay is granted under Type 2 rules (up to three years, renewable without total cap), you become eligible to sponsor dependents, and your years begin counting toward the permanent-residency working requirement.

The strategic risk is timing: if you reach the end of your five Type 1 years without having passed the Type 2 exam, you have no automatic extension. This is why the conversion has to be planned from early in the Type 1 period, not attempted in the final year.

7. Timing it against the five-year clock

Because the Type 1 cap is cumulative — total, across every renewal and every employer, not a fresh five years each time you change jobs — the five years are a hard budget. The implication is that every month of Type 1 is a month you should also be building toward the supervisory skill the Type 2 exam checks. Workers who treat Type 1 as "just working" and leave the exam to the last year tend to run out of runway, because reaching supervisory competence and passing a harder sector exam is not something that happens in a final few months.

A practical sequencing: use the first two to three years on Type 1 to reach the skill level your field expects, sit the Type 2 exam with enough buffer to retake it if needed, and leave margin before year five so that the change-of-status paperwork clears before the cap bites. If your field requires a specific number of years of experience (as manufacturing does), work backwards from that number against your start date.

8. When your field has no Type 2

Not every worker can convert, and the two main exclusions need a different plan.

Nursing care (介護) has no Type 2 track. The long-term route for care workers is instead to qualify as a certified care worker (介護福祉士) and then move to the separate 「介護」 status of residence, which is a different working status outside the SSW framework. So a care worker's career ladder climbs out of SSW into the 介護 status rather than up to SSW Type 2.

The four 2024 fields — automobile transportation, railways, forestry, and timber — are Type 1 only at present. If you are in one of these, Type 2 is not currently available to you, and your long-term planning has to account for the five-year cap with no in-programme escape route unless future reforms open Type 2 for your field. This is exactly why checking Type 2 availability before choosing a sector (§3) matters so much.

9. Type 2 and the permanent residency pathway

Permanent residency is where the Type 1 vs Type 2 split has its longest-reaching consequence. Permanent residency generally asks for around ten years of continuous residence in Japan, with at least five of those years spent on a working status of residence. The decisive rule for SSW holders is that Type 1 years do not count toward that five-year working requirement — they build residence, but not the working-status portion. Type 2 years do.

In practical terms, the realistic route from SSW to permanent residency runs entirely through Type 2: arrive on Type 1, convert as early as your field and skill allow, and then accumulate the five working-status years (and the broader ten-year residence) on Type 2. This is why the requirements article frames Type 2 as the tier to plan toward from day one — it is the only SSW tier that makes permanent residency mathematically achievable within the standard rules.

Summary

The Type 1 to Type 2 conversion is the hinge of an SSW career, and it rewards workers who plan for it early:

1. Type 2 is available across most — but not all — fields. Construction, shipbuilding, building cleaning, manufacturing, agriculture, fishery, food and beverage manufacturing, accommodation, and food service offer it; nursing care does not, and the four 2024-added fields are Type 1 only for now. Confirm your field on the official SSW directory.
2. The bar is supervisory skill, verified by a sector exam (for example, JAIM for manufacturing or JAC for construction), often with a track record of experience. There is no Japanese-language test for Type 2.
3. Conversion is a change of status filed once you have passed the exam and built the record; budget the time against the cumulative five-year Type 1 cap.
4. The day you convert, three things change: the total cap lifts (each grant up to three years, unlimited renewals), your spouse and children can join you under 家族滞在 (Dependent) status, and your years start counting toward permanent residency.
5. If your field has no Type 2, plan a different long-term route — nursing care leads to the separate 介護 status, and the 2024 fields currently have no in-programme path beyond the five-year cap.
