These are the actual causes based on real rejection cases. Most rejections are preventable — and most stem from compliance issues the applicant wasn't aware of at the time they accumulated.
Rejection #1 — Most Common
Residence tax (住民税) arrears
ISA electronically cross-checks municipal tax records for every PR application since 2024. Even a single year with outstanding 住民税 is flagged. Most common during job transitions or freelance periods when tax filing was missed.
Fix: Pay all arrears, obtain payment certificates, prepare written explanation for the gap year.
Rejection #2
Pension enrollment gaps
The gap between leaving one employer's shakai hoken and enrolling with the next employer — or in national pension — is the most common source. A 1-2 month gap during a job change is the most frequently seen issue.
Fix: Pay outstanding national pension. For older gaps beyond 2-year limit, apply for exemption. Document all periods.
Rejection #3 (post-April 2027)
Holding a 1-year or 3-year visa at application time
From April 2027, applicants must hold a 5-year visa grant. Currently receiving 1-year grants means compliance issues must be resolved before reaching the 5-year grant — adding years to the PR timeline.
Fix: Identify why you receive short grants. Resolve the underlying issue. Work toward 3-year, then 5-year grants over subsequent renewals.
Rejection #4
Missing 14-day job-change notifications
Required within 14 days of any employment change. Many foreign residents are unaware this rule exists. During PR review, officers check the notification history for all employer changes during the entire Japan residency period.
Fix: File all missing notifications immediately via oishi.moj.go.jp. Include explanation letter in PR application. Late is far better than never.
Rejection #5
Income gaps or sharp unexplained drops
An extended period of unemployment or a sudden large income decrease without explanation raises financial stability concerns. Officers review the full income history across all years in Japan, not just recent years.
Fix: Prepare written explanation for gap/drop period. Document savings, partner income, or other financial stability during the period. Ensure current income is stable and sufficient.
Rejection #6
Activity mismatch or conduct issues
Working outside permitted visa activities — even in the distant past — is reviewed during the full residency history check. Repeated traffic violations, past immigration violations, or inconsistencies between declared and actual activities are flagged.
Fix: Disclose all history honestly. Document the timeline and any corrective actions. Consult a specialist before applying if any conduct concerns exist.
