Why You Might Need to Get Wedding Documents Translated

Since Japan requires official documents in Japanese, you’ll need to have them translated before submission.

If your home country’s documents are not in Japanese, they must be translated before submission to local government offices. 

Common documents that require translation include:

• Marriage Certificate – for legal recognition in Japan or your home country. You may need to translate into your language to understand.
• Certificate of No Impediment (CNI) or Affidavit of Competency to Marry – to prove that you are single and that you are qualified to marry (i.e.: the age). This needs to be translated into Japanese.
• Passport or ID – for identity verification of yourself. This needs to be translated into Japanese.
• Birth Certificate (if your partner is Japanese) – to confirm the identity and nationality of your partner.

If your country does not provide a certificate of No impediment to the Affidavit of Competency to Marry, you will need to create an alternative document with a Japanese translation.

Without accurate translations, your marriage registration may be delayed or rejected. You can still translate yourself, but choosing a professional and reliable translation service can help you to release some burden.

• Accuracy and Experience – Look for providers experienced in legal and marriage-related translations to avoid errors.
• Turnaround Time – Some translations take a few days, while others may take weeks. Choose a service that fits your timeline.
• Cost and Transparency – Prices vary based on document type and urgency. Be sure to get a clear quote before proceeding.

Step-by-Step Process for Wedding Documents Translation 

If you need to get your wedding documents translated, follow these steps:

1. Check the required documents
2. Select a translation service 
3. Submit your documents to your translator or translation agency
4. Wait until the translation is completed
5. Submit the documents to the authorities
6. Review if it needs re-submission
7. Receive approval 

💡 Take Note: When submitting your translation documents, you may need a stamp (inkan or hanko) from the translator. In Japan, this stamp is used as a form of verification to confirm identity. If you are the translator, you can submit the document with your stamp. However, finding a Japanese stamp with your name may be difficult, and you might need to ask for customization to create your stamp.

For this reason, it may be more convenient to work with an agency or a freelance translator who already has a Japanese stamp. If you’re unsure whether a stamp is required in your area, check with your local city hall.

DIY Translation: Pros and Risks

Translating the wedding documents yourself saves costs, but this also comes with some risks. If certification is required, professional service is the safest option to avoid delays or rejections.

Pros:

• Cost Savings – You will translate it on your own, so it will be free of charge
• Faster Process – Only you are involved, so the translation can be completed faster

Cons:

• Rejection – You might get rejected due to the translated documents
• Legal Inaccuracies – You might miss information that is legally required
• Time-Consuming – You may need to resubmit a few times until it is accepted
