With side jobs becoming more common in Japan, Engineer visa holders also have similar needs. However, there are specific rules under the residence status system.
Reference: Immigration Services Agency of Japan, “Permission to Engage in Activities Other Than Those Permitted”
Basic Rules
No Permission Needed
If the side work falls within Engineer visa activities:
| Case | Permission | Reason |
|---|---|---|
| Engineer work at another company | Not needed | Within Engineer visa scope |
| Freelance Engineer-level work | Not needed | Same scope |
| Translation/interpretation for another company | Not needed | Engineer visa work |
Permission Required
If the side work falls outside Engineer visa activities:
| Case | Permission | Reason |
|---|---|---|
| Convenience store / restaurant part-time | Required | Not Engineer visa work |
| Delivery services (Uber Eats, etc.) | Required | Simple labor |
| Language school teaching | Required | ”Instructor” visa category work |
Prohibited Side Work
| Type | Reason |
|---|---|
| Factory line work | Simple labor |
| Construction site labor | Outside Engineer visa scope |
| Adult entertainment industry | Legally prohibited |
Key Considerations
- Check your employer’s rules — many prohibit side work
- File notifications within 14 days for new contracts
- Side income over ¥200,000/year requires tax filing
- If freelance income exceeds main job, a status change may be needed
