Japanese subtitling breaks most of the assumptions built into Western subtitle tooling: no spaces between words, a character-per-second budget that means something entirely different, and line breaks that have to respect phrase units a space-based splitter cannot see.

Character counting is not word counting
A Japanese subtitle carries far more meaning per character than a Latin-script one, so raw character limits imported from an English workflow produce cues that are either cramped or wastefully short. Reading speed is a per-project setting in Hello8 precisely so a Japanese track can be tuned against its own budget rather than inheriting a European default.
Transcription quality comes first
Everything downstream depends on the transcript. Japanese runs through our highest-accuracy transcription tier, with speaker diarization, and the original track stays editable alongside the translation so a mis-heard proper noun can be fixed once at the source instead of in every target language.
What's automated and what isn't
Our grammar-aware line breaking covers French and English today. For Japanese, line breaks follow universal rules: punctuation, clause markers and reading speed. The AI Reviewer flags grammar, translation and punctuation issues, and the final read is yours. We'd rather say exactly what is automated than pretend to more.
Frequently asked questions
- Do you handle vertical text or furigana?
- Not currently. Our output is horizontal subtitle text in standard formats (SRT, VTT, ASS). If your delivery spec requires vertical layout, tell us before you start so we can confirm the fit.
