About this language pair

English and Japanese: one pair, two directions

From English into Japanese you translate for business partners, clients and authorities abroad; from Japanese into English for UK authorities, banks and employers. In both directions a native specialist translator with domain experience works on your text.

Where an authority asks for a certified translation, we bring in a sworn translator. The translation carries the required declaration, signature and stamp, and we arrange the Apostille or consular legalisation your destination country demands.

Translation from English to Japanese

Translation from English to Japanese: we deliver in the right mix of Kanji, Hiragana, and Katakana per document type. Technical texts lean on Katakana for loanwords and specifications, while legal texts use Kanji-heavy notation. Our Japanese translators tune the honorific layer (keigo: sonkeigo / kenjōgo / teineigo) to the hierarchy between sender and Japanese recipient. Sectors we regularly serve: automotive supply chain (Toyota, Honda, Nissan), robotics (Fanuc, Yaskawa), pharma (PMDA submissions), and cross-border M&A.

Translation from Japanese to English

Translation from Japanese to English: for UK subsidiaries of Japanese multinationals, Home Office casework, family reunification, M&A due diligence reports, and patent documentation. We use correct Hepburn-Romaji transliteration for Japanese proper names where the English context requires it, and deliver certified via ITI/CIOL-registered translators where required.

In practice

How such a project runs

A company opens a branch abroad: website, employment contracts and product documentation go from English into Japanese, while incorporation documents and bank records travel the other way. One project manager guards terminology and planning in both directions, and confirms per document whether certification or legalisation is required.

How does Ecrivus handle the three Japanese scripts in a translation?
Our Japanese translators deliver in the mix of Kanji, Hiragana, and Katakana that the document type requires. Technical texts lean on Katakana; legal on Kanji-heavy notation; consumer communication balances all three.
How is the honorific level (keigo) determined?
We tune sonkeigo (respect for the addressee), kenjōgo (humility for one's own party), and teineigo (neutral-formal) to the hierarchy between sender and Japanese recipient. For contracts and business correspondence this matters: an incorrect level reads as impolite to the recipient.
Will my Japanese translation be accepted by the Home Office or UK courts?
Yes, when certified: for UK Home Office, courts, and councils Ecrivus delivers certified Japanese translations via ITI/CIOL-registered translators.
Which document types are standard for English ↔ Japanese?
M&A documentation, due diligence reports, technical specifications (automotive, robotics), patents, annual reports, family records, and immigration documents.
How quickly will I receive a quote?
On working days you receive a response within 30 minutes. The lead time is confirmed in the quote based on document type, volume, and required certification.
