Marriage in Japan.
Are you a New Zealander getting married in Japan? Here is what you need to do.
1. Contact your local office – 区役所 (kuyakusho) and ask them what documents they require.
The New Zealand embassy states that you need a certificate of no impediment (application form here), your local passport, and your foreigner registration card. Depending on where you live, you will also need your birth certificate (not a copy) and translated versions of the above (not passport). You may translate the documents by yourself.
2. Once you have these you need to fill out a 婚姻届 (konintodoke) and have two people (anybody really) sign the document.
3. Your Japanese spouse will need a copy of their Family register (if you are not getting married in their local ward) and some other things (I would tell you, but your spouse can handle all of that anyway)
4. Take it all to the local ward office and hand it in.
Below are copies of the documents you will need if you are a New Zealand citizen and the Marriage Certificate you get afterwards (The big version ~1500yen – there is a smaller one for around 300 yen.). Please note that these have had all personal data erased, and that the Certificate of No Impediment pages have had the Japanese written on them; they do not come with a translation.
