After the Thai amphur wedding, the Japanese spouse must register the marriage at the Japanese Embassy Bangkok or directly with their honseki municipality in Japan within 3 months. The Thai partner then applies at the Embassy for a Spouse of Japanese National (日本人の配偶者等) visa, supported by a Certificate of Eligibility issued by the Immigration Services Agency. Standard processing is 1–3 months; the visa is granted with a 1-, 3-, or 5-year status of residence and full work rights.
The Japanese Embassy Bangkok issues a Konin Yoken Gubi Shomeisho (Certificate of Legal Capacity to Contract Marriage) for Japanese citizens who wish to marry a Thai national in Thailand. The certificate is issued at the Consular Section, 177 Witthayu Road, Pathum Wan, with appointments booked online through the Embassy's reservation system. The fee is THB 600 (the equivalent of JPY 2,500 at the consular rate) and the certificate is issued within 30 minutes of the appointment.
The Japanese spouse must bring a passport, a Koseki Tohon (family register extract) issued within the last 3 months from the honseki municipality in Japan, and proof of residence (Juminhyo). The Koseki Tohon does not need to be apostilled if it is the original issued by a Japanese municipality and presented within the 3-month freshness window — the Embassy stamps the certificate against the Koseki record directly.
Once issued, the certificate is in Japanese and English. NYC's MFA-registered Japanese-Thai translator translates it into Thai (1 business day, THB 1,500), and the translation is legalised at the Thai MFA Department of Consular Affairs. Thailand's Hague Apostille membership (effective 14 December 2024) now allows a single Apostille on the translation instead of the older multi-stamp consular chain, halving the turnaround time.
Under Japanese family law (Civil Code Articles 739 and 741), the marriage of a Japanese national abroad must be reported (todokede) within 3 months. The Japanese spouse can either (a) submit the report (Konin Todoke) in person at any municipal office in Japan or (b) lodge it at the Japanese Embassy Bangkok, which forwards it to the honseki municipality. Either route updates the Koseki Tohon to reflect the new marriage and the Thai spouse's particulars within 2–4 weeks of receipt by the honseki office.
Required documents at submission: the Konin Todoke form (we provide a pre-filled bilingual version), the original Thai Kor.Ror.2 marriage certificate plus its Japanese translation (NYC provides a sworn Japanese translation by a translator registered with both the Thai MFA and the Japanese Embassy), and the Thai spouse's birth certificate plus Japanese translation. The Embassy charges no fee for forwarding to Japan.
Until the Koseki is updated, the Thai spouse cannot be entered as 配偶者 (spouse) on the Japanese spouse's Koseki — and many subsequent steps (visa, Juminhyo registration in Japan, dependent tax status, National Health Insurance dependents, child registration) depend on the updated Koseki. NYC tracks the honseki-side update on behalf of clients and notifies them once the Koseki Tohon reflects the marriage, typically 3–5 weeks after Embassy submission.
The Spouse of Japanese National visa is issued only after the Immigration Services Agency in Japan grants a Certificate of Eligibility (COE). The Japanese spouse — or a designated proxy in Japan — files the COE application at the Regional Immigration Bureau covering their residence in Japan. Processing time is 1–3 months for a complete application. Required documents include: the updated Koseki Tohon showing the marriage, evidence of the Japanese spouse's income (the last 12 months' Gensen Choshu Hyo and Juminzei Kazei Shomeisho), residential evidence (rental contract or property title), passport-style photos, and a written ‘Reason for Sponsoring the Spouse’ in Japanese explaining how the couple met, the relationship timeline, and joint plans in Japan.
Once the COE is issued, the Japanese spouse couriers the original to Bangkok. The Thai spouse books an Embassy visa appointment via the online portal, attends with the COE original, the Embassy visa application form, two photos, and the THB 1,200 visa fee. Standard processing is 5–7 business days; in practice, COE-supported applications are decided within 3 business days.
On arrival in Japan, the Thai spouse is issued a Residence Card (在留カード) at the airport on a 1-year, 3-year, or 5-year status of residence (the duration is determined by the immigration officer based on stability of the relationship and the sponsor's income — first-time applicants typically receive 1 year, with extensions to 3 or 5 years thereafter). The Thai spouse has full unrestricted work rights including employment, self-employment, study, and public-sector roles. After 3 years on a Spouse status (or 5 years including 1 year of marriage), the spouse becomes eligible to apply for Permanent Resident status.
Failing to file the marriage with the honseki municipality within 3 months breaches Article 741 of the Civil Code and triggers a small administrative fine; more seriously, it delays the COE application and therefore the spouse's arrival in Japan.
The Japanese Embassy and the honseki municipality both require translations by a sworn Japanese-Thai translator. Translations by unsworn translators or family members are rejected at honseki — costing 4–6 weeks.
Although there is no statutory minimum, Immigration informally expects the Japanese sponsor's annual income to be at least JPY 2.5–3 million per year for a 2-person household. Below this, the COE is often denied with a generic ‘insufficient sponsorship’ notice.
Sponsor earned JPY 6.8 million p.a. at a Tokyo trading company. NYC handled the Embassy Konin Yoken Gubi Shomeisho, Watthana amphur registration, the post-amphur Konin Todoke submission (via the Embassy back-channel), and the Thai-side Apostille on the Kor.Ror.3 for use in Japan.
Sponsor's pension alone (JPY 1.8 million p.a.) was below the informal threshold. NYC restructured the application to add JPY 12 million in time-deposit savings at a Chiba shinkin bank as supplementary evidence; COE issued on second submission 10 weeks later.
1) Affirmation of Freedom to Marry (single-status affidavit) issued by Japan Embassy (Konin Yoken Gubi Shomeisho); 2) Passport + valid Thai entry stamp / visa; 3) Sworn Thai translation of the affidavit; 4) MFA Department of Consular Affairs legalization of the Thai translation; 5) Thai ID + house registration for the Thai spouse. NYC handles every step under one fixed-price package.
Standard turnaround is 5–10 business days end-to-end (embassy appointment → translation → MFA → district office). Express service in 3 business days is available for an additional THB 3,500.
Any amphur in Thailand can register the marriage. NYC recommends Bang Rak, Watthana, or Pathum Wan in Bangkok — staff are experienced with foreign documents, speak English, and offer same-day appointments. Outside Bangkok, Chiang Mai, Phuket, Pattaya, and Koh Samui are also straightforward.
Yes, but the recognition path is consular legalization (not Apostille). NYC will translate the Thai marriage certificate, get it legalised by the Thai MFA, and then attested at the Japan embassy in Bangkok before you take it home.
Most amphurs in Bangkok and tourist provinces have English-speaking officers, but Thai law requires that both parties fully understand what they are signing. NYC provides a court-approved interpreter (English or your native language) at the district office for THB 2,500.
Our all-in package for Japan nationals starts at THB 9,000 and covers embassy escort, sworn translation, MFA legalization, and amphur booking. Embassy fees (charged directly by Japan Embassy (Konin Yoken Gubi Shomeisho)) and any post-marriage apostille for home-country use are additional.
The Thai amphur registration is the legal marriage under Thai law. There is no separate ‘Embassy wedding’ — instead, the Japanese spouse must report the existing Thai marriage (Konin Todoke) to the honseki municipality within 3 months, either directly in Japan or via the Japanese Embassy Bangkok. Once the Koseki is updated, the marriage is fully recognised under Japanese law without any further ceremony.
Typically 3–5 months end-to-end: 3–5 weeks for the Konin Todoke to update the Koseki, 1–3 months for the Certificate of Eligibility at the Immigration Services Agency in Japan, and 3–5 business days for the visa stamp at the Japanese Embassy Bangkok. Complete and well-evidenced applications with sponsors earning above JPY 4 million p.a. typically resolve in the shorter 3-month bracket.
Yes — the visa grants unrestricted work rights from day one of arrival in Japan. The Thai spouse can take employment in any sector, including teaching, healthcare, public service, and self-employment, without an employer sponsorship change. They can also study at any institution without a separate Student visa. Work is one of the strongest factors Immigration considers when extending the status from 1 year to 3 or 5 years.
永住権 (PR): 3 yrs of marriage + 1 yr continuous residence in Japan as Spouse of Japanese National. 帰化 (naturalisation): 3 yrs of marriage + ≥1 yr spousal residence, ~N4 Japanese and stable income. NYC partners with a Tokyo 行政書士 for both routes.
After your Thai marriage registration, the Kor.Ror.2/3 certificate must still pass MFA Apostille before Japan will recognise your marital status for a spouse visa.
