Apostille corridor & MOFA Japan workflow
Japan joined the Hague Apostille Convention on 28 July 1970 — one of the earliest signatories. Thailand acceded on 30 June 2026 (in force for Thailand 28 February 2027) and Apostilles became enforceable on 25 January 2025. The corridor is now bidirectional single-leg: MOFA Tokyo (or regional Legal Affairs Bureau) issues Apostilles on Japanese documents; MFA Chaeng Wattana issues Apostilles on Thai documents. Embassy of Japan Bangkok and Royal Thai Embassy Tokyo no longer perform legalization for member-state purposes.
MOFA Japan Apostille procedure: documents issued by Japanese authorities (Koseki Tohon family register, Kekkon Juri Shomeisho marriage acceptance certificate, university diplomas) are Apostilled at MOFA Tokyo (Kasumigaseki) or via regional Legal Affairs Bureau (Homukyoku) for notarised private documents. Fee: JPY 0 (free) — Japan's MOFA does not charge for Apostille service. Processing: same-day to 3 business days. NYC coordinates via partner agents in Tokyo, Osaka, Nagoya for Thai families needing Japanese docs Apostilled while resident in Thailand.
Spouse of Japanese National (Nihonjin no Haigusha) visa
The Spouse of Japanese National visa allows a Thai spouse to live and work in Japan without occupational restriction, leading to PR eligibility after 3 continuous years of residence (vs 10 years for standard work visas). Application is processed by the Immigration Services Agency via Certificate of Eligibility (COE, Zairyu Shikaku Nintei Shomeisho) sponsored by the Japanese spouse. COE processing: 1-3 months. Visa stamp at Embassy of Japan Bangkok: 5 business days, fee JPY 3,000 (single) / JPY 6,000 (multiple).
Required Thai documents (all Apostilled by MFA): Marriage Certificate (Kor.Ror.3) + sworn EN translation, Birth Certificate + EN translation, Royal Thai Police Clearance + EN translation (valid 3 months), Household Registration + EN translation. Japan-side: Koseki Tohon (full family register), Question Form (Shitsumonsho) detailing relationship history with photos/messages/travel records, Japanese spouse's tax certificates (Nozei Shomeisho × 3 years) showing minimum JPY 3 million annual income. NYC handles the full Thai-side bundle in 7-10 business days.
HSP point system & Engineer/Specialist visa routes
Highly Skilled Professional (HSP, Koudo Senmonshoku) is Japan's 70-point fast-track visa launched 2012, expanded 2023 to include J-Skip (bypass points if salary JPY 20M+ for academic/business, JPY 40M+ for research). Point categories: academic background (PhD 30pt, Master 20pt, Bachelor 10pt), professional career (10pt per 3 years up to 25pt), annual salary (10-40pt scaling JPY 4M-10M+), age (15pt under 29), JLPT (N1 15pt, N2 10pt), bonus for top global universities (Chulalongkorn, Mahidol on Times Higher Ed list earn 10pt bonus). 70+ points = HSP visa; 80+ points = PR in 1 year.
Engineer/Specialist in Humanities/International Services is the standard work visa for IT engineers, business analysts, marketing, and international affairs roles. Requires: bachelor's degree relevant to job OR 10+ years equivalent experience, employment contract with Japanese company, monthly salary ≥ Japanese national minimum for the prefecture. COE processing 1-3 months. Documents: Apostilled diploma + sworn EN translation, Apostilled transcript, CV, Japanese company's Toki Bo (corporate registry), Kessan Hokokusho (financial statement).

Kekkon Todoke marriage registration at Ward Office
Thai-Japanese marriages registered in Japan require Kekkon Todoke (notification of marriage) at the Ward Office (Kuyakusho/Shiyakusho) of the Japanese spouse's registered domicile (Honseki). This creates a new Koseki entry recording the marriage. The marriage takes legal effect from the date of Ward Office acceptance — NOT from any prior Thai registration. Couples already registered in Thailand must still submit Kekkon Todoke for Japan to recognise the marriage; Thai Kor.Ror.3 alone is not sufficient.
Documents required for Kekkon Todoke (Thai spouse side, all in original + Japanese translation): (1) Birth Certificate + Apostille + JP translation; (2) Single Status Affidavit issued by Royal Thai Embassy Tokyo OR by Amphur in Thailand + Apostille + JP translation; (3) Passport copy; (4) Household Registration + Apostille + JP translation. Japanese spouse side: Koseki Tohon (within 3 months), Hanko (registered seal), valid ID. Ward Office processing: same-day acceptance. After acceptance, Kekkon Juri Shomeisho is issued for subsequent visa applications.
