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.

Reach Japanese-speaking audiences with professionally subtitled marketing and social media content.
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.
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.
Our grammar-aware line-breaking engine currently models French and English. For Japanese, segmentation uses universal rules based on punctuation, clause markers, and reading speed, and the AI Reviewer plus a human pass carry the quality. We would rather tell you which part is automated than claim a depth we do not have.
