Translate English subtitles to Japanese
Upload an English subtitle file. The source and target languages are already fixed for this workflow.
A direct English-to-Japanese subtitle workflow
Skip language selection and focus on producing natural, readable Japanese subtitles from an existing English track.
Keep the existing timing
Imported cues remain the timing reference, so the workflow can focus on text instead of rebuilding timestamps.
Review natural Japanese, politeness and line breaks
English often states subjects and pronouns that natural Japanese can omit. Review です/ます versus plain style, names and loanwords in katakana, and line breaks so each cue reads naturally rather than literally.
Export for your platform
Use SRT, VTT, ASS or SBV depending on your editor, player or publishing workflow.

Translate English subtitles to Japanese – FAQ
Do I need to select English and Japanese manually?
No. English is fixed as the source and Japanese as the target on this page.
Will the subtitle timing change?
The imported subtitle cues remain the timing basis. The workflow focuses on translating the subtitle text.
How should politeness, names and Japanese line breaks be handled?
Match the scene and audience: choose an appropriate です/ます or plain style, avoid unnecessary pronouns carried over from English, check proper-name and loanword transliteration, and adjust Japanese line breaks for readability while keeping the cue timing.
What about ASS styles or VTT metadata?
Complex styling, positioning or player-specific metadata should be checked after translation. Keep the original file as a reference when these details matter.
