Bringing Your Spouse or Family to Japan: Dependent Visa Basics
Updated: 2026-09-03
Quick answer
Hi, I'm Miya. If you're already living in Japan and want your spouse or child to join you, the usual path is the dependent status — kazoku taizai in Japanese. It's a separate procedure from registering a marriage or renewing your own status, so it helps to think of it on its own terms.
The short version: you, as the resident here, apply first in Japan for a document called the Certificate of Eligibility, and then your family member uses it to apply for their visa at a Japanese consulate abroad. It takes some patience and paperwork, but it's a well-worn road, and I'll sketch out the shape of it below.
What the dependent status covers
The dependent (kazoku taizai) status is for the spouse or child of someone who already holds a longer-term working or study status in Japan. The idea is that your family lives here with you, dependent on your residence, rather than each needing their own work-based status. Whether a particular family relationship qualifies depends on your own status and situation, so it's worth confirming your case rather than assuming.
This is different from statuses meant for spouses of Japanese nationals, and different again from a work status a family member might pursue on their own. Because those distinctions matter, I always suggest checking your specific circumstances against the official Immigration Services Agency guidance before you start gathering anything — it saves a lot of backtracking later.
The Certificate of Eligibility route
For most families the process runs through the Certificate of Eligibility, often shortened to COE. As the sponsor already in Japan, you apply for the COE at your regional immigration office on behalf of your family member. It's essentially immigration confirming in advance that the relationship and your circumstances fit the status, which makes the later visa step much smoother.
Once the COE is issued, you send it to your family member abroad, and they take it to a Japanese embassy or consulate to apply for the actual visa. After that comes the trip to Japan and receiving a residence card on arrival. Doing the COE first is what turns a potentially uncertain application into a clear, sequential one.
Documents you'll commonly need
Expect to show three broad things: proof of the family relationship, proof of your situation as the sponsor, and proof of where everyone will live. Relationship proof often means official records such as a marriage or birth certificate; sponsor proof usually touches on your employment and income; and residence proof covers your home in Japan. The exact combination depends on your status and family setup.
I'm being deliberately general here because document lists get updated and vary case by case, and I don't want you preparing the wrong thing. Please confirm the current, complete list officially through the Immigration Services Agency or your regional immigration office. This is planning guidance from me, not legal advice — when in doubt, the official source wins.
Rough timeline and a little patience
Realistically this is a multi-step, multi-week process rather than something you finish in an afternoon. The COE application takes time to review, then there's mailing it abroad, the consular visa step, and finally travel — each stage has its own waiting. Planning backwards from when you'd like your family to arrive helps you start early enough.
So my honest advice is to build in buffer and keep gentle track of where each step stands. Things move at their own pace, and that's normal. If you begin assembling documents while you still have time, the waiting feels far less stressful than racing a deadline you set too tight.
Staying connected keeps it all moving
Almost every part of this quietly runs through your phone: scanning and emailing documents, booking the immigration office and consular appointments, and receiving notifications about your application's status. Keeping an active Japanese number as the sponsor means none of those threads go quiet while you're mid-process, and messages don't slip past you.
And once your family lands, a Japanese number for each family member makes settling in so much easier — signing into apps, verifying accounts, and staying reachable. With Rakuten Mobile you only need the residence card, and if the phone supports eSIM it can be ready in about 15 minutes with no store visit. Check the official page for current conditions, and I'll gladly help with the mobile part.
