About Japanese translation
Japanese translation, where the register decision comes first
Japanese is written with three systems used together: kanji for most content words, hiragana for grammar and native vocabulary, and katakana for loanwords and emphasis. The balance between them is an editorial choice rather than a fixed rule, and it changes how formal, technical, or approachable a text feels.
Japanese expresses the relationship between writer and reader through keigo, and the level chosen affects verb forms throughout the document rather than a handful of pronouns. A corporate announcement, a software interface, and a consumer campaign each call for a different level, and getting it wrong reads as either presumptuous or oddly stiff.
There is a practical dimension too. Japanese usually contracts against English, sometimes substantially, and it is written without spaces between words, so line breaking follows its own rules. Layouts sized for English rarely translate across without adjustment.
At GoLocalise, we work with native Japanese translators matched to the subject matter, and every text is reviewed by a second linguist before delivery.

How can we help you?
Your project manager has everything covered
One point of contact from brief to delivery, and a second linguist on every text before it reaches you.
Brief review
We review your source material and your audience, and agree up front the decisions this language forces before anyone starts translating.
Linguist assignment
Your project goes to a native Japanese translator with experience in the relevant field.
Translation and review
The text is translated and then checked by a second native linguist for accuracy, consistency, and register.
Delivery and consistency check
Files are delivered in the format you need, with the choices agreed at the brief applied consistently from the first line to the last.
Areas of expertise
What we specialise in
From corporate video and eLearning to documentary, advertising and subtitles — always audiovisual, with the register decision taken before a word is written.
Corporate and brand video
Company films and internal communications, written to fit the shot rather than overflow it.
eLearning and training video
Course modules and training films, with terminology kept consistent across the programme.
Documentary and interviews
Factual programming and interviews, where the register shifts between speakers and has to survive the move.
Advertising and social video
Campaigns and short-form video, cut to land inside the time available.
Subtitles and captions
Frame-accurate subtitles kept within a comfortable reading speed.
Voice over and dubbing scripts
Scripts timed to the original, ready for a native voice in the booth.
Built for video and audio
Getting Japanese right on screen
Japanese brings its own on-screen considerations, and its writing system makes subtitling a discipline of its own.
Character limits, not just CPS
Japanese subtitling works to character-count limits and its own line-break rules (kinsoku), mixing kanji, hiragana and katakana — we spot to those conventions, not English ones.
Compact but dense
Japanese reads compactly on screen, but density and pacing need care so captions stay readable against fast cuts.
Politeness levels (keigo)
Japanese encodes formality, so we set the register — polished for corporate, warmer for consumer — for both voice-over scripts and captions.
Timed, not dumped
We deliver spotted subtitle files and two-column voice-over scripts timed to the original — never a loose document that still needs spotting.
Deliverables
How your Japanese translation arrives

Most common questions
How much does Japanese translation cost?
Japanese translation is priced per word or per character for text and per minute for audiovisual, depending on volume, subject and turnaround. Send your files for a free, itemised quote, backed by our Price Match Promise.
Are your Japanese translations done by native linguists?
Yes. Native Japanese linguists translate at the right level of politeness (keigo) and a second reviews every text, so it reads naturally for your audience.
Can you deliver Japanese subtitles and voice over too?
Yes — Japanese translation, subtitling to Japanese conventions and voice over from one team, so your whole project stays consistent.
Do you subtitle Japanese to Japanese conventions?
Yes. We spot to Japanese character-count limits and line-break rules (kinsoku), mixing kanji, hiragana and katakana correctly — not English characters-per-second norms.
What level of formality should my Japanese translation use?
It depends on the relationship the content implies. Business correspondence and official announcements call for a formal register, product interfaces and consumer marketing generally use a politer neutral form, and internal material can sit lower still. The choice affects the whole document rather than a few phrases, so we confirm it at the brief stage.
Will the Japanese version be shorter than my English text?
Usually, in character count. That sounds convenient and creates its own layout problems: text sized for English can look sparse, and headings lose their visual weight. Japanese also breaks lines differently, since it is written without spaces. Send us the working files and we will flag where the design needs adjusting.
Can you translate for both Japanese and other Asian markets at once?
We can run them together, but they are separate translations rather than adaptations of each other. Japanese, Korean, and Chinese are unrelated languages with different scripts, grammar, and conventions, despite being grouped commercially. Where a project covers several, we manage them centrally so terminology stays aligned across versions.
Can machine translation handle Japanese?
It is one of the weaker pairs with English. The grammar is structured very differently, subjects are routinely omitted and inferred from context, and politeness levels are applied inconsistently by machine output, which frequently produces text that is comprehensible but reads as unmistakably foreign. Our Japanese translations are produced by native linguists and reviewed by a second.
How quickly can a Japanese translation project be delivered?
Most short documents are delivered within 24 to 48 hours. Word count, subject complexity and turnaround all move the date, and your project manager will confirm the timeline at the start.
What do you need from us to quote Japanese translation?
Less than people expect: the document, script or subtitle file, its word count, what the text is actually for, and the date you need it by. A draft is fine — we would rather quote on what exists than wait for a final version that eats your deadline. A named project manager comes back with an itemised quote, normally within four working hours.
How quickly will we hear back, and who will we be dealing with?
More than half of enquiries get a reply within thirty minutes during office hours (Monday to Friday, 9am to 6pm UK time), and the itemised quote normally follows within four working hours. After that you have one dedicated project manager who owns the job from brief to final file — not a ticket queue, and not a different name on every email. If it is easier, call +44 207 095 5730 and ask for them by name.
We are still pitching and the budget is not signed off. Can we still get a Japanese quote?
Yes, and it is one of the commonest reasons people get in touch. Tell us it is for a pitch and you get a figure you can put in front of your own client, itemised so it stands up to being picked apart, with no obligation and no follow-up sales calls if the pitch goes elsewhere. If it lands, the quote still holds and we already know the project.
