Same-day delivery is available for documents under 1,500 words at rush rates (contact us for a quote).

- Will Thai Immigration and MFA accept your translations? +
Bangkok Translation prepares certified Japanese translations for Thai Immigration, the Ministry of Foreign Affairs, and the Japanese Embassy in Bangkok. Our official translation services include a certification statement, company seal, and translator details where required. If an authority raises a translation-quality issue, we correct and re-certify the document at no charge.
- Do you translate Japanese to Thai directly? +
We offer direct Japanese-to-Thai translation using native Thai speakers with JLPT N1/N2 certification, or native Japanese speakers with Thai language proficiency. For complex legal or technical documents, we can also provide trilingual Japanese-Thai-English versions for accuracy and international usability.
- What is a koseki tohon and do you translate it? +
Koseki tohon is the Japanese family registry—an official government document that records births, deaths, marriages, divorces, and family relationships. It's required for marriage registration in Thailand, visa applications, and many legal processes. We regularly translate koseki tohon and understand its formatting, including historical kanji variants and registry-specific terminology.
- Do I need MFA legalization for my Japanese documents? +
It depends on where you are submitting the documents. Some Thai government offices accept certified translations without MFA legalization, while embassies and certain official processes may require MFA-legalized translations. We can advise based on your destination office and handle the MFA process if needed (usually 3-5 business days; contact us for current fees).
- Are your translators native Japanese speakers? +
For Japanese-to-English and Japanese-to-Thai work, we use native Japanese speakers with English or Thai proficiency, or qualified Thai/English linguists with advanced Japanese ability. Each document is reviewed by a second qualified linguist before delivery.
- What if the embassy rejects my translated document? +
If an authority raises a translation-quality issue, we re-translate or re-certify at no additional charge. Rejections for reasons outside the translation — missing originals, expired certificates, incomplete applications, or changed office requirements — are not covered, but we will help you identify the next step.
