About GaijinOS
What GaijinOS is for
GaijinOS helps foreign residents turn life events in Japan into structured next steps, with official sources kept close to the work.
Positioning
Verified action plans for foreign residents in Japan.
What you get
Start from a real situation such as moving, visa renewal, job changes, insurance updates, or residence-card issues. GaijinOS organizes the next steps, deadlines, documents, and source links in one place.
How it works
This is an action system, not a chatbot. The goal is to help you understand what likely matters now, what to verify, and what to do next before you open the next official page.
Privacy and data
GaijinOS is designed to keep sensitive data out by default. It does not ask for My Number, passport numbers, residence card numbers, or document uploads just to make a plan.
