Two different visa categories cover family relationships in Japan, and they're easy to confuse because both are sometimes loosely called "family visas." They have meaningfully different rules, particularly around work rights, so it's worth being clear on which one applies to your situation before anything else.
Two Different Categories, Not One
Spouse of Japanese National (日本人の配偶者等) applies if you're married to a Japanese citizen. It comes with no work restrictions at all — you can work any job, full-time, in any field, exactly as a Japanese national could.
Family Stay (家族滞在) applies if you're the spouse or child of someone holding a work visa (技人国, Business Manager, Specified Skilled Worker Tier 2, and others) rather than a Japanese citizen. This category has real work restrictions, covered in detail below.
Which one applies if your partner has permanent residency?
If your spouse holds Permanent Residency (rather than being a Japanese citizen), the relevant category is Spouse of Permanent Resident (永住者の配偶者等) — a related but distinct status, similar in spirit to the Japanese-spouse category but with its own specific requirements, including a minimum period of marriage and prior residence in Japan.
What Spouse of Japanese National Actually Requires
The core requirement sounds simple — a legally valid marriage to a Japanese national — but the application is genuinely scrutinized, and the burden of proof sits entirely with the applicants. There's no interview; the entire review happens through submitted documents, which makes the documentation itself the whole case.
What immigration is actually screening for
Because this category has no education or work-history requirements — unlike most work visas — it has historically been a target for sham marriage arrangements. As a direct result, immigration scrutinizes the genuineness of the relationship closely: how the couple met, the length of the relationship before marriage, whether marriage took place in both Japan and the foreign spouse's home country as required, cohabitation status, and the Japanese spouse's financial stability. A marriage that's completely genuine can still face real scrutiny if the documentation doesn't tell a clear, consistent story.
Building a credible application
Photos together spanning the relationship, message history showing ongoing communication, records of visits if the relationship was long-distance before marriage, and a clearly-written explanation of how the relationship developed all matter more than people initially expect. A short courtship — getting married within a few months of meeting — doesn't automatically disqualify an application, but it does invite more scrutiny, and having more supporting documentation matters proportionally more in that situation.
The marriage must be valid in both countries
Legal marriage needs to be completed both under Japanese law and under the law of the foreign spouse's home country — registering only in Japan isn't sufficient on its own for many nationalities. Requirements vary significantly by country, so confirm the specific process for your home country well before applying rather than discovering a gap during the visa application itself.
Cohabitation matters, and ongoing
Immigration generally expects the couple to actually live together, and an extended period of separation without a clear, legitimate reason (such as a temporary work posting) can affect both the initial application and especially renewal. This status genuinely depends on the marriage being lived, not just legally registered.
Family Income — What's Actually Required
If the Japanese spouse has low or no income, the application isn't automatically rejected, but it does need to be addressed directly with supporting evidence — savings, financial support from family, or a credible and specific plan (such as a confirmed job offer with a start date) showing the household can support itself without becoming a public burden.
Sham Marriage — A Genuinely Serious Risk, Both Ways
This needs to be stated plainly because the consequences are severe. Sham marriage in Japan is treated as a crime, not just a visa technicality. The foreign spouse risks visa revocation and deportation, typically with a 5-year (sometimes longer, occasionally permanent) re-entry ban. The Japanese spouse, if knowingly participating, can face criminal charges for falsifying a public document (公正証書原本不実記載罪), carrying potential imprisonment or fines. Anyone who arranges or profits from facilitating sham marriages faces even more serious criminal liability.
If you suspect you've been deceived
If you entered a marriage in good faith and later discover it was not genuine on your partner's side, this is a situation to address with an immigration specialist or legal counsel immediately rather than navigating alone — being an unknowing victim is treated very differently from knowing participation, but that distinction needs to be established clearly and early.
Family Stay — The Work Restriction That Catches People Off Guard
If you're on Family Stay status (dependent of a work-visa holder, not a Japanese citizen), the default position is that you cannot work. This surprises people who assume any spouse visa comes with full work rights — it doesn't, and the distinction from the Spouse of Japanese National category above matters enormously here.
The part-time work workaround
Family Stay holders can apply for permission to engage in supplementary activity (資格外活動許可), which — once granted — allows part-time work up to 28 hours per week, the same limit that applies to international students. This isn't automatic; it requires a separate application to immigration. Full-time employment isn't available under this permission regardless of how many hours you'd like to work.
An important exception worth knowing
If the work-visa-holding spouse upgrades to Highly Skilled Professional status with sufficiently high points, their dependent spouse gains the right to work full-time without needing the separate supplementary-activity permission — one of the genuine practical advantages of the points system covered in our Highly Skilled Professional guide.
The Permanent Residency Fast-Track for Spouses
Being married to a Japanese national meaningfully shortens the path to permanent residency compared to the standard 10-year requirement. If the marriage has continued for 3 or more years and you've lived in Japan continuously for at least 1 of those years, you become eligible to apply for PR — a substantially faster timeline than almost any other route, including the Highly Skilled Professional fast-track for most applicants.
This applies even on a different visa status
If you're currently on a work visa (such as 技人国) rather than Spouse of Japanese National status, but you are married to a Japanese national meeting the duration requirements above, the same accelerated PR eligibility applies to you. You don't need to be on the spouse visa specifically to benefit from this — being legally married to a Japanese national for the required period is what matters.
A Few Practical Notes
Family Stay holders' status is directly tied to the principal visa holder's status — if the principal visa is not renewed or is revoked, dependent Family Stay status is affected accordingly. If your relationship circumstances change significantly (separation, divorce), this affects your visa status and needs to be addressed proactively with immigration rather than left unaddressed, since continuing to hold a spouse-based status after a marriage has genuinely ended creates its own complications at the next renewal.
