Japanese document translation requires name checks against the passport and prior Japanese records, followed by the recipient’s certification requirements.
Common Japanese translations: birth/marriage/divorce certificates, degree/transcripts, employment letters, financial proof, POAs and corporate documents. Used for Japanese work visas (SSW, Engineer, HSP), university applications, marriage registration in Japan, or language school admissions.
Before work begins, confirm the recipient’s current certification, name-format and furigana rules against the passport and prior Japanese records.
Thai names are transliterated to katakana phonetically. We use Modified-Hepburn for names and verify against existing Japanese documents (ARC, Zairyu Card) for consistency. Katakana spelling errors are a top cause of visa rejection.

The Japanese SSW visa requires Japanese-translated: health certificate (Japanese form), JLPT result, skill assessment, birth certificate, CID. All documents must clear MFA + Embassy of Japan. We provide complete packages.
Marriage registration at Japanese ward offices requires Japanese-language Affirmation of Marital Status from the Royal Thai Embassy in Japan, with related document translations. We coordinate with the Thai Embassies in Tokyo and Osaka for streamlined processing.
Japan is an Apostille member, but Thailand will issue Apostilles from 28 February 2027 — until then Thai documents require MFA legalisation followed by the destination embassy. Some Japanese agencies (e.g., the Immigration Bureau) may have additional requirements, which we verify per case.
Japan records civil status in the family register (戸籍謄本 / 戸籍全部事項証明書), which carries births, marriages, divorces and children in one document. Translate every entry, not only the part that seems relevant: a Thai district office reads the whole register to confirm single status or earlier marriages.
A Japanese municipal office (市区町村役場) registering a marriage usually wants Japanese translations of the Thai documents with the translator named. Requirements vary between offices, so check with the office where you will file.
Japanese records often use era years such as 令和 (Reiwa) or 平成 (Heisei). Convert them clearly to the Gregorian year; likewise convert Buddhist Era years on Thai documents when translating into Japanese.
Thai names appear in katakana, which allows several spellings. Reuse the katakana already on earlier Japanese records such as the residence card (在留カード). Name seals (印鑑) should be identified in the translation by whose seal they are.
Japanese nationals have no stand-alone birth certificate; birth, marriage and children are recorded in a single family register (戸籍謄本, koseki tōhon). When a Thai–Japanese couple marries at a Thai district office, the office usually asks for the koseki with a Thai translation, and the Japanese spouse must then report the Thai marriage to the Japanese embassy or a municipal office in Japan within the period Japanese law sets.
Japanese documents use era years — Reiwa 6 (令和6年) is 2024 CE and 2567 BE. Getting the conversion wrong by one year throws ages and marriage dates out of line with every other document, so we show both BE and CE with the original era year in brackets.
Thai names in Japanese documents are written in katakana, which can be romanised several ways. Before translating, we ask which katakana spelling appears on the residence card (在留カード) or earlier Japanese records so the name does not drift between offices.
Notarial Services Attorneys in Thailand must hold a licence from the Lawyers Council of Thailand under the 2003 Notarial Services Regulation.

Read full text →Japanese authorities accept names only in katakana matching the passport reading. Guessing kanji for a Thai name without supporting documents creates mismatches and rejection.
The Japanese family registry (koseki) must be translated in full, including transfer history and marginal notes; translating only the main section leads ward offices to refuse it.
Japanese documents carry overlapping page seals and pagination marks; the translation must note each one or the set is treated as incomplete.
Each Japanese ward office has slightly different forms and translation rules; we confirm with the destination office before translating to avoid resubmission.
