N4 is the entry ticket to Japan's largest blue-collar labor market — it satisfies the Specified Skilled Worker language requirement and opens factory, care, food and hospitality work nationwide. It is a floor to build from, not a level to stay at.
Key facts
- Visa unlocked
- SSW (with field exam)
- Main sectors
- Care, food, factory, hotel
- Typical pay
- ¥180–250k/month
- Where jobs are
- Nationwide, not just Tokyo
- Next milestone
- N3 — supervisor track
What N4 actually sounds like at work
You can greet, confirm tasks, read hiragana/katakana and basic kanji signage, and survive a routine shift. What you cannot yet do: handle claims, phone calls or nuance. Employers know this — jobs at this level are structured so that routine is 90% of the day.
The map of N4 work
| Sector | Entry pay (indicative) | Language reality |
|---|---|---|
| Caregiving | ¥180–230k + allowances | Speaking-heavy, fastest learning curve |
| Food service / manufacturing | ¥180–230k | Routine phrases, manual-driven |
| Factory work | ¥200–260k | Least talking, slowest learning |
| Hotel housekeeping / kitchen | ¥180–230k | Guest-facing roles need more |
All are SSW fields — the field exam, not the language test, is usually the harder gate.
Treat N4 as year zero
The single highest-return investment at this level is the next JLPT level. N3 opens team-leader tracks; N2 changes your market entirely — compare what N2 unlocks. Choose a workplace where you must speak, set a test date, and let the visa ladder (SSW (i) → (ii)) climb alongside the language one.
Common mistakes & warnings
- Pay figures are indicative ranges from public sources; night shifts and allowances shift the totals significantly by workplace.
- At N4, you can follow instructions but not negotiate — take a translator or support person for contract signing, and read our employment contract guide first.
- Beware brokers marketing "N4 office jobs". Genuine office hiring below N3 is extremely rare; such ads usually hide dispatch factory work.
Frequently asked questions
Which SSW fields are most accessible at exactly N4?
Caregiving (with its own language add-on), food service, food manufacturing, cleaning and agriculture recruit the most at this level. Construction and manufacturing want the same level plus stronger field exams.
How long does N4 → N3 take while working full-time?
Commonly 8–18 months of steady study. Workplaces where you speak Japanese all day are an accelerator — one reason care work upgrades language faster than line work.
Does N4 help outside SSW?
Yes — many part-time and dispatch employers use it as a screening baseline, and it satisfies the language element some municipalities look for in support programs.
