Japan to Canada Spousal Sponsorship
Last updated: January, 2026
Japan is one of the simplest countries when it comes to Canadian spousal sponsorship requirements. There are no extra IRCC forms, no military declarations, and no country-specific questionnaires.
However, Japanese civil documentation is unique, and incorrect or incomplete family registry documents are the #1 cause of delays.
With accurate documentation and well-organized evidence, applicants can move through the sponsorship process smoothly and confidently. If at any point you feel unsure about a document or a specific step, our consultants are available to guide you and help avoid costly delays.

Country-Specific Documents
For Japanese applicants, the Koseki (family registry) is the core of the application. IRCC relies on it to verify identity, marriage history, and family composition.
You must include:
✓ Koseki Tohon (Full Family Registry Extract) and, if applicable:
✓ Kaiseigen Koseki Tohon
(used when the original registry was reorganized due to marriage, divorce, adoption, or a family line split)
Important details:
- Must be complete, showing all current and historical family members
- Must be accompanied by a certified English or French translation
- Must include a copy of the original Japanese document
This is the most frequently mishandled item—accuracy here prevents almost all delays.
Success Factors
Japan has a highly reliable civil registry system, which IRCC trusts. When:
- the Koseki is complete,
- translations are certified, and
- all forms match the details recorded in the registry…
applications tend to move efficiently and with minimal issues.
