Changing jobs in Japan is normal and increasingly common — but for foreign workers it is also an immigration event. The rules differ sharply by visa: gijinkoku holders move freely with a notification, SSW workers change within their field through a procedure, and everyone's renewal record remembers how it was done.
Key facts
- Gijinkoku
- Free move + 14-day notification
- SSW
- Same field only, via procedure
- Notice period (law)
- 2 weeks; contracts often say 1 month
- Resignation blocked?
- Employers cannot refuse it
- Renewal impact
- Job continuity is reviewed
Two clocks run when you switch
The labor clock: give notice per your contract (law says 2 weeks; one month is the polite standard), finish the handover, receive your final pay and gensen chōshūhyō (tax slip). The immigration clock: notify within 14 days of leaving and again within 14 days of starting — a five-minute online filing that a surprising number of people forget, and renewals remember.
Strategy differs by visa
- Gijinkoku: the freest movers. Check duty-match for the new role; when in doubt, get the optional eligibility certificate first.
- SSW: movement within your field via a defined procedure — and your 5-year clock keeps running, so move for real improvements, not sideways.
- Dependent/spouse-based: no immigration constraint on the job itself; only the labor clock applies.
How employers read your history
Japanese hiring has softened on job-changing — mid-career mobility is now mainstream — but pattern still matters: 3 jobs in 2 years invites questions; a move every 3–4 years with a clear reason reads as ambition. Prepare the “why” in the same pull-not-push framing as an interview answer.
Common mistakes & warnings
- The 14-day notification to immigration after changing employers is a legal duty separate from anything your employer does — missing it surfaces at renewal time.
- Long unemployment between jobs (as a rule of thumb, over 3 months without active job hunting) can justify revocation for work-visa holders. Line up the next job before leaving when possible.
- If your new duties differ from your current visa category, you need a change of status first, not just a notification — verify before the start date.
Frequently asked questions
Can my employer stop me from resigning?
No. Civil law lets indefinite-term employees resign with 2 weeks' notice regardless of company rules. Withheld final pay or threats about your visa are labor-office matters, not real leverage.
Does changing jobs hurt my permanent residency chances?
Orderly changes with continuous employment and clean notifications do not. What hurts is gaps, missed notifications, or a pattern that looks unstable in the 3 years before applying — see the PR requirements.
Should I use a certificate of employment eligibility when switching?
The shūrō shikaku shōmeisho is optional but useful for gijinkoku moves into different-looking roles — it pre-clears that the new job fits your status, so the risk doesn't land on your next renewal.
