Translation / 翻訳

Documents Japan will accept, in English you can read.

Certified translation of official documents, both into and out of Japanese. Family registers, certificates, licences, contracts, medical records — translated in Kumamoto, with notarization arranged when you need it.

Send us your document Most official documents ready in three business days

A translation that gets rejected at the counter has cost you two trips.

Immigration offices, city halls, banks, universities and embassies each have their own expectations for how a translated document should look and what has to accompany it. We translate to those expectations, attach a certificate of translation at no extra charge, and tell you in advance if notarization is likely to be required.

Every translation is done by a native speaker of the target language who understands the subject, then read against the original. Machine output is not sent to clients.

Services

What we do.

Certified document translation

Official and personal documents translated and issued with a certificate of translation, signed and stamped by Adastra, at no extra charge.

Notarization

Where an authority requires a notarized translation, we prepare the supporting documents, attend the notary public's office and post the result to you.

Native-speaker translation

A native speaker of the target language translates; a native speaker of the source language resolves ambiguity in the original before it is finalised.

Business & legal documents

Contracts, company registration papers, financial statements, technical specifications and manuals, handled by translators with the relevant background.

Websites, print & subtitles

Site and app copy, brochures, menus, maps and video subtitles. We can also deliver print-ready files rather than loose text.

Advice, not just translation

If a phrase will not land with a Japanese reader — or a Japanese phrase will not land in English — we say so and propose the alternative.

Official documents

Flat rates for official documents.

Everything else is quoted per project — send us the file and you will get a price. USD figures are an approximate guide only, converted at ¥150 = $1; yen amounts are authoritative.
