What this document is
This is not an application — it is a notification: free, no photo, quick to do. But it is an obligation for residence-status holders, and Immigration cross-checks the dates on your resignation and new contract against the dates you reported — so file it and keep your record clean.
What it must show
- Holders of 技術・人文知識・国際業務 (and Research · Care · Skilled Labour · Specified Skills · Highly Skilled…) — that is you.
- Leaving the old employer → one notification of 「契約の終了」 within 14 days of the last day.
- Joining the new employer → one notification of 「新たな契約の締結」 within 14 days of the start date.
- Filed neither and already started the new job → report both at once, with the true dates (late is better than never).
- Also required when the company changes name, moves, or is dissolved — same form.
