Imagine this: You’re standing under a canopy of cherry blossoms, the scent of spring in the air, your partner’s hand in yours. It’s your dream wedding in Japan! But before you pop the champagne—or the sake—there’s one little thing standing in the way: paperwork.
Welcome to the koseki (戸籍), Japan’s family registry system, where romance meets bureaucracy. If you’re planning a wedding in Japan, understanding the koseki is crucial, especially if one of you is Japanese. But don’t worry—I’ve got you covered with a step-by-step guide that’s both informative and (dare I say) entertaining. Let’s break it down so you can focus on what really matters—celebrating your love in one of the most breathtaking wedding destinations in the world.
What Is the Koseki and Why Does It Matter?
The koseki is Japan’s official family registry, which records births, marriages, divorces, and deaths. Instead of individual records like in many Western countries, Japan organizes records by family units. When two people marry, one partner (usually the wife) is added to the other’s koseki, or they create a new registry together.
Wait—Does That Mean I Leave My Own Family?
Well… in a way, yes. When a Japanese citizen gets married, they leave their birth family’s koseki and start a new one with their spouse. It’s like a symbolic fresh start—legally and emotionally.
For couples where one partner is non-Japanese, only the Japanese spouse has a koseki, but the marriage will still be recorded in Japan’s legal system.
Can Foreigners Have a Koseki?
Short answer: No.
Foreigners do not have a koseki, but they can still legally marry in Japan. If you’re marrying a Japanese citizen, they will need to update their koseki, while you’ll typically provide proof of your single status from your home country—often called a Certificate of No Impediment or an equivalent document.
👉 Pro tip: Check with your embassy in Japan to see exactly what documents you’ll need. Some countries require additional paperwork to recognize a Japanese marriage abroad.
How to Legally Get Married in Japan (Without Losing Your Mind)
So, you’re ready to make it official? Here’s what you need to do:
Step 1: Gather Your Documents
- If one of you is Japanese: A full copy of your koseki tohon (戸籍謄本).
- If you’re a foreigner: A Certificate of No Impediment or an equivalent document from your country.
- A completed marriage registration form (kon-in todoke 婚姻届), available at city halls.
- Identification (passport, residence card).
- Two witnesses (over 20 years old) to sign the form.
👉 Fun fact: No wedding ceremony is required in Japan to be legally married. Just the paperwork!
Step 2: Submit Your Documents
Take everything to the local city hall (shiyakusho 市役所) where the Japanese partner’s koseki is registered. Once everything is approved, your marriage is official!
Step 3: Celebrate!
You did it! Now it’s time to celebrate with some sake, sushi, and—of course—a stunning wedding photoshoot. Speaking of which…
Does the Koseki Affect Your Wedding Plans?
Not really! The koseki is about legal registration, but your actual wedding ceremony can be whatever you want. Whether you’re dreaming of a traditional Shinto wedding, a Western-style chapel ceremony, or a beach elopement in Okinawa, the paperwork won’t dictate the style of your big day.
For Japanese couples:
- One spouse (usually the wife) must legally change their surname to match their partner’s, unless they take special legal steps.
For international couples:
- Some countries require additional steps to recognize a Japanese marriage, so check with your embassy.
