A Japanese status of residence is permission for a defined activity. When the activity changes, you usually need a change of status, not only more months on the old label: Extend stay keeps the same category.
When is a change required?
Typical triggers include graduating and starting a covered job, switching from Dependent to your own work status, moving from study to designated activities, or other ISA-listed paths. Starting paid work on a status that forbids it without permission creates illegal-work risk even if your card still looks valid.
File at the Regional Immigration Services Bureau for your address, or through the online residence application system when you meet My Number Card and MyNaPortal requirements. Permission fees commonly mirror extension pricing (often JPY 6,000 at the counter, JPY 5,500 online when granted). Standard processing often runs about one to two months. Do not begin the new activity until permission is issued unless ISA guidance for your case says otherwise.
What evidence usually matters?
Each status has its own checklist. Work routes want employer contracts, company registration extracts and tax history. Family routes want marriage or dependency proof. Student-to-work packs mix graduation papers with the new job file. Passport, current residence card and a matching municipal address trail sit underneath: Register address and Apply for residence.
After permission, update health insurance and pension routes if your employment category changed: Choose health insurance. Banks and employers may ask for the new card: Open a bank account. Japanese-only counters are common: Bureaucracy without Japanese.
Common misconceptions
Assuming an employer offer letter alone changes your status fails. ISA must grant the change before the new activity is lawful.
Assuming every Temporary Visitor can switch in-country also fails. Many long-stay routes still need Certificate of Eligibility logic or outbound reapplication; read the page for your target status.
Summary
Treat a new activity as a change-of-status file with status-specific evidence. Wait for permission, then refresh the residence card, insurance and bank records to match.
