The clearest Japan first route for many Chinese applicants: school obtains COE, then visa.
Route overview
Status of Residence: Student
Typical timeline / duration: 2-6 months
Important notes
Acceptance by Japanese school/university/language institution; school normally obtains Certificate of Eligibility; applicant submits passport, visa application, photo, COE or copy, and any consulate-specific documents.
Proof of ability to pay tuition/living costs or financial supporter evidence may be requested; exact documents vary by consulate/nationality.
Part-time work requires separate permission to engage in activity other than permitted by status.
State COE-based process and avoid giving one universal checklist because consulates can vary.
