Good Conduct Requirement for Naturalization｜How Traffic Violations, Criminal Records, and Tax Arrears Affect Your Application
Introduction
One of the conditions for naturalization approval is “good conduct” (Article 5, Paragraph 1, Item 3 of the Nationality Act). However, the specific standards for “good conduct” are not explicitly defined in the law.
This article explains the specific impact of traffic violations, criminal records, and tax/social insurance arrears — issues that frequently arise in practice — on naturalization screening.
What Is the Good Conduct Requirement
Article 5, Paragraph 1, Item 3 of the Nationality Act establishes “good conduct” as a condition for naturalization. This requires that the applicant’s behavior is befitting a member of Japanese society.
The screening is evaluated from three main perspectives.
| Perspective | What Is Checked |
|---|---|
| Criminal/violation history | Existence and severity of criminal penalties and traffic violations |
| Tax obligation fulfillment | Payment status of income tax, resident tax, business tax, etc. |
| Social insurance payments | Payment status of health insurance and pension |
Impact of Traffic Violations
Minor Violations
Minor violations such as parking infractions and seatbelt violations (handled through traffic fines) will not immediately result in rejection if they are few in number.
However, the following are practical benchmarks.
| Period | Violation Count Benchmark |
|---|---|
| Past 5 years | 5 or more may affect screening |
| Past 2 years | 2 or more will trigger careful review |
Tip: If you have many violations, it is recommended to establish a clean record for a period of 1-2 years before applying.
Serious Violations
Drunk driving, driving without a license, and personal injury accidents have a significant impact on the good conduct requirement.
- Fine imposed → Generally 5+ years must pass after completion of penalty
- Imprisonment imposed → Generally 10+ years must pass after completion of sentence
- Suspended sentence → Evaluated based on years elapsed after the suspension period ends
Submission of Driving Record Certificate
Naturalization applications require submission of a 5-year driving record certificate (issued by the Japan Safe Driving Center). Please prepare one issued within the past 2 months.
Impact of Criminal Records
If You Have a Criminal Record
The required waiting period varies depending on the type and severity of the crime.
| Type of Penalty | Required Waiting Period |
|---|---|
| Fine | 5+ years after completion |
| Imprisonment (suspended) | 5+ years after suspension period ends |
| Imprisonment (served) | 10+ years after completion |
Note: Immigration law violations (overstaying, unauthorized activities, etc.) are evaluated particularly strictly. Cases with immigration violations often require 10+ years after resolution.
Points to Watch Even Without Criminal Records
- Arrest records (including non-prosecution) are also considered
- Domestic issues (DV, stalking protection orders) may have an impact
- Connections to antisocial organizations are a major grounds for rejection
Tax and Social Insurance Arrears
Tax Arrears
The most common problem in good conduct screening is tax arrears.
| Tax Type | Subject of Review | Impact Level |
|---|---|---|
| Income tax | Payment status of those with filing obligations | Very high |
| Resident tax | Special/ordinary collection payment status | High |
| Individual business tax | For sole proprietors | High |
| Corporate/consumption tax | For company owners | Very high |
- Outstanding tax at the time of application generally results in rejection
- If there were past arrears, it is advisable to wait 1-2 years after full payment
- Late payment tax records are also reviewed
Social Insurance Arrears
National Health Insurance and National Pension payment status are also checked.
- Payment records for the most recent 2 years are subject to review (may expand to 5 years)
- Employees enrolled in company social insurance typically have no issues
- If there are periods of non-payment, please make retroactive payments before applying
Tip: It is common to forget to switch to National Pension when changing jobs or starting a business. Please check your enrollment history at the pension office.
Measures When Concerned About Good Conduct
- First, accurately assess your current situation — Obtain driving record certificate, check tax certificates, inquire about pension enrollment history
- Resolve issues first — Clear all outstanding payments, wait after violations
- Use the Legal Affairs Bureau’s pre-consultation — Confirm screening prospects for your individual situation
- Consult a specialist — When there are unfavorable factors, application strategy is especially important
