About Japanese subtitling
Japanese subtitling does not scale down from European rules
Japanese subtitling does not work the way European language subtitling does. Japanese is written with three systems used together: kanji, hiragana, and katakana, and a single kanji can carry what English needs several words to say. Text contracts sharply against English in character count.
That sounds convenient until you look at reading speed. Japanese is also written without spaces between words, so line breaks follow their own conventions rather than falling at a convenient gap.
At GoLocalise, we work with native Japanese subtitlers and every file passes linguistic and technical QA before delivery.


Which do you need?
Open captions, closed captions or SDH
Three different deliverables that people often ask for by the wrong name. Here is the short version.
Open captions
Burnt inSubtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and it fixes the line breaks and the typography at delivery.
- Always visible
- Breaks and rendering fixed at delivery
- Delivered as a finished video file
Closed captions
SwitchableA separate file the viewer can turn on and off, and that can carry several languages at once. The standard for YouTube, Vimeo and the streaming platforms.
- Viewer controls them
- Multiple languages from one video
- Indexed by search engines
SDH
AccessibilitySubtitling for the deaf and hard of hearing: dialogue plus speaker IDs and the sound effects and music cues that carry meaning.
- Speaker identification
- Non-dialogue audio described
- Meets accessibility requirements
Subtitles or captions? The two terms are often used interchangeably. Strictly, subtitles translate the dialogue for viewers who can hear the audio, while captions are same-language and add speaker labels and sound cues for viewers who cannot. We produce either — translated Japanese subtitles or same-language Japanese captions and SDH — in whichever form your platform and audience require.
What we subtitle
Japanese subtitling for every kind of content
Japanese subtitling spans corporate, eLearning, streaming and entertainment work, and the politeness level shifts between them. These are the formats we handle most.
Corporate & training video
Internal comms, onboarding and product training subtitled for global teams and LMS delivery.
eLearning & online courses
Timed, readable subtitles for course platforms, MOOCs and instructional video.
Documentary & factual
Festival, broadcast and streaming documentaries, including interview clean-up and on-screen text.
Advertising & social
Burnt-in captions for muted autoplay on Instagram, TikTok, YouTube and paid social.
Streaming & OTT
Platform-spec subtitle and caption files for VOD, OTT and broadcast delivery.
Accessibility (SDH & closed captions)
Same-language SDH and closed captions to meet WCAG and accessibility requirements.
Events, webinars & conferences
Recorded talks, town halls and webinars captioned for on-demand viewing.
E-commerce & product video
Short product and explainer videos captioned to lift conversion and reach.
How can we help you?
Your project manager has everything covered
One point of contact from brief to delivery, and both a linguistic and a technical check on every file.
Brief review
We review your video, your audience, and the level of formality the content calls for.
Template and translation
Where needed, we create an English subtitle template first, then send it to a native Japanese subtitler.
Timing and quality checks
Subtitles are timed against the video and checked for reading speed in characters per second rather than words, line length, kinsoku line-breaking, and format compliance.
Delivery and display check
Files delivered in the format you need, checked to render with the kanji and kana intact.
Our standards
The specs we work to
Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Japanese unless your style guide says otherwise.
Maximum per line
Full-width; 11 when set vertically
Maximum on screen
Half-width characters count as half
Reading speed
Seven in SDH — kanji carry more per character
Minimum duration
Seven seconds maximum
If Japanese is shorter than English, why does timing still matter? Because reading speed is measured in what a viewer can absorb, not in characters saved. Kanji carry more meaning per character and take longer to process than Latin letters, so the comfortable characters per second rate is lower. A line that looks short can still be too fast to read, which is why Japanese subtitling standards differ from European ones rather than simply scaling down.
Deliverables
Professional subtitle formats
We adapt your existing translations into subtitle format or create subtitles from scratch, in Japanese, English or any other language. And if the project needs a timed script or a plain document instead, we deliver that too.
Standard text-based
Compatible with most platforms and players.
Broadcast & professional
For broadcasters, post houses and streaming delivery specs.
Burnt-in video
A finished file with the Japanese subtitles baked into the picture.

Japanese specifics
Politeness levels, and where a line can break
Japanese encodes the relationship between speakers through politeness levels — plain, polite and honorific forms each carry meaning. In subtitling that has to track what is actually happening on screen, scene by scene, rather than follow a single house setting applied across the whole file regardless of who is speaking to whom.
In practice: colleagues, strangers and friends do not address one another the same way, and flattening that across a file removes information the dialogue is conveying. For corporate and instructional content a consistent polite register is usually right; for drama or dialogue-driven material, it should follow the speakers.
The other decision is where a line can break. Without spaces, Japanese follows typographic conventions rather than looking for a gap: established rules govern which characters may not begin or end a line, and a subtitler applies them the way an English subtitler avoids splitting a noun from its article. Software that breaks on character count alone gets this wrong.

Most common questions
If Japanese is shorter than English, why does timing still matter?
Because reading speed is measured in what a viewer can absorb, not in characters saved. Kanji carry more meaning per character and take longer to process than Latin letters, so the comfortable characters per second rate is lower. A line that looks short can still be too fast to read, which is why Japanese subtitling standards differ from European ones rather than simply scaling down.
How are line breaks handled without spaces between words?
By following Japanese typographic conventions rather than looking for a gap. There are established rules about which characters cannot begin or end a line and where a break is acceptable within a phrase, and a subtitler applies them the way an English subtitler avoids splitting a noun from its article. Software that breaks purely on character count gets this wrong constantly.
What level of politeness should the subtitles use?
Whatever the relationship on screen implies. Colleagues, strangers, and friends do not address one another the same way in Japanese, and flattening that across a file removes information the dialogue is conveying. For corporate and instructional content, a consistent polite register is usually right; for drama or dialogue-driven material, it should follow the speakers.
Do you produce SDH and closed captions in Japanese?
Yes. Alongside standard subtitles, we produce files that include sound effects, music cues, and speaker identification for deaf and hard of hearing viewers, formatted to the specification your platform or broadcaster requires.
How quickly can a Japanese subtitling project be delivered?
For a short video, 24 to 48 hours is typical. What moves that is whether a Japanese transcript already exists, the length of the finished cut, and how many output formats you need. The timeline is agreed with your project manager before work begins.
How much does Japanese subtitling cost?
Japanese subtitling is charged by the running minute of video, from £20. Setting the politeness level and breaking lines to Japanese typographic rules are part of the work; the figure also follows running time, transcription, SDH or burnt-in delivery, and the count of output formats. Every project is priced individually, backed by the Price Match Promise.
Can you work from our existing Japanese transcript or SRT?
Of course. An existing transcript or SRT becomes our spotting file, re-breaking any line where a tool has split the text at a point Japanese typography does not allow. Otherwise we transcribe the Japanese audio first. The same two-stage QA, linguistic and technical, covers every file.
Can we drop your Japanese subtitle files straight into our edit?
All the usual ones. You get SRT, VTT, STL and TTML that keep the Japanese character set and the line breaks intact into Premiere Pro, Final Cut Pro, DaVinci Resolve and the major online editors — or burnt into the picture as a finished MP4/MOV.
What do you need from us to quote Japanese subtitling?
Less than people expect: the video, or a link to it, its running time, which platform or broadcaster it is going to, and the date you need it by. A rough cut is fine — we would rather quote on what exists than wait for picture lock and lose a week of your schedule. 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.
What if we find a cheaper Japanese quote somewhere else?
Send it over. Our Price Match Promise covers like-for-like work, and because our quotes are itemised you can see exactly what is being compared — which is usually where the gap turns out to be, in a revision pass, a licence or a delivery format that the cheaper figure quietly left out. If it really is the same work for less, we match it.
