COE 不交付と大使館のビザ拒否の違い
About nine in ten failures happen before you ever visit VFS: Immigration in Japan declines to issue the COE. The school is notified with a reason category. Embassy refusals after a COE are less common and usually come from a poor interview, a document mismatch discovered at the embassy, or new information (such as a previous refusal that was not declared).
10の理由とそれぞれの対策
| Reason | What Immigration saw | Fix before reapplying |
|---|---|---|
| 1. Sponsor's funds not credible | Large balance deposited recently; income on paper cannot produce that saving | 6–12 months of steady statements; income proof matching the balance; 3 years' tax; explain any large transfer (land sale deed, FDR maturity) |
| 2. Sponsor relationship unclear | Uncle/aunt/cousin sponsor without proof of relationship or reason to pay | Relationship certificate from local government; a letter explaining why this relative pays; prefer a parent sponsor where possible |
| 3. Inconsistent documents | Name spelling, date of birth or parents' names differ across SSC/HSC certificates, NID and passport | Correct the record at the education board / NID office first, or attach an affidavit explaining the variation |
| 4. Unexplained study gap | Years between HSC and now with no employment or study record | Employment certificate, trade licence or affidavit for every period; an SOP that tells the story honestly |
よくある質問
Can I reapply for a Japan student visa after a COE rejection?
Yes. There is no waiting period or ban after a normal refusal. Fix the stated reason with documents and apply for the next intake, usually 3–6 months later. Fraud-related refusals are different and can carry a multi-year ban.
Does Immigration tell me the exact reason for refusal?
Immigration gives the school a reason category (for example, 'doubts about ability to pay expenses'), not a detailed letter. The school or your institute can usually request clarification at the Immigration office.
Will I get my money back if the COE is refused?
Tuition is not yet paid at the COE stage, so you lose only the school's application/screening fee and translation costs. Check your institute's written refund policy for its service charge before paying anything.
Is a bank loan accepted as proof of funds?
Generally no — Immigration wants to see genuine family savings supported by income. A loan that appears as a sudden deposit is a common reason for refusal.
